Competition horses develop the disease very early as a result of intensive training at a young age. As part of a large collaborative project between the Swedish University of Agricultural Sciences (SLU) and Sahlgrenska University Hospital (SU), researchers at Chalmers have been involved in developing a new method to enable early diagnosis of osteoarthritis in horses.</b></p><div>“Osteoarthritis is a chronic joint inflammation where the disease process is slow and difficult to diagnose at an early stage. But to be able to treat it, it is important to identify the early stages”, says Eva Skiöldebrand, professor of general pathology at the Swedish University of Agricultural Sciences (SLU) with a focus on osteoarthritis in horses and humans.<br /><br /></div> <div>“Together with professors Stina Ekman at SLU and Anders Lindahl at SU, our research group has developed biomarkers, or more specifically, identified new neoepitopes* that are generated when protein from articular cartilage and underlying subchondral bone (bone under articular cartilage) is broken down by inflammation, which is the hallmark of the disease. The research group has been able to verify the biomarkers in serum and synovial fluid in horses with varying degrees of osteoarthritis and studied the effect of training and the effect of circadian rhythm, which is a major research breakthrough, says Eva Skiöldebrand.<br /><br /></div> <div>The use of biomarkers allows the disease to be detected earlier and the occurrence of serious injuries to be prevented – and the effectiveness of drugs for the treatment of osteoarthritis can be evaluated.</div> <div><br /></div> <div><strong>Early diagnosis with saliva test</strong></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Health/Udda%20format/Artros_bild_450x350.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />One person who has played a large part in a related research breakthrough at the end of 2021 is Moa Lord, a former biotechnology student and now a research assistant in materials physics at Chalmers. <span style="background-color:initial">Together with the research group at SLU and SU, she has developed a new method for quantifying biomarkers in saliva in horses, under the supervision of professor Eva Skiöldebrand, Susanne Nyström, PhD in molecular biology, BMA at SU, and Magnus Karlsteen, associate professor of materials physics at Chalmers and responsible for Chalmers' initiatives in equine technology.</span></div> <div><br /></div> <div>“We wanted to develop a method that could easily fit into the daily horse keeping. Saliva sampling is a non-invasive sampling method in contrast to synovial fluid samples and blood samples, which means that you can take more samples without creating discomfort in the horse. Detection and quantification of the biomarker in saliva enables an easier way to monitor how the biomarker is affected by training and surfaces, and detection of early signs of disease”, says Moa Lord.<br /><br /></div> <div><strong>Self-developed bit for horses</strong></div> <div>To facilitate saliva sampling, Chalmers has refined the method by producing a special bit for horses.</div> <div>“When we discovered that we could use saliva to measure the biomarker, we wanted to investigate how the biomarker changes during a training session when the strain on the joint increases. That is why we at Chalmers have designed and constructed a bit with space for sampling tubes. The bit collects the saliva while riding or driving the horse. This enables us to collect samples in a simpler way and that the training session can be completed without a major interruption to take a sample”, says Moa Lord.<br /><br /></div> <div>“This bit and the ability to detect the biomarker in saliva is the basis for a completely new diagnostic method, there is no one who has done something similar before. The current test tubes in the saliva collection bit work well. But we are working for the long-term goal of implementing an electronic graphen sensor e in the bit, which can provide continuous measurement values of the biomarker and test results directly on site. This would enable the horse owner from home to consult with a veterinarian and follow the development of the disease and act by working preventively to eliminate incipient disease”, says Magnus Karlsteen.<br />​<br /></div> <div>“Considering that a large number of competition horses develop osteoarthritis, the bit is important for the preventive work. Being able to measure the biomarker in saliva means that we can measure the effect of training when the horse runs and rides on different surfaces and at different paces. Then you can tailor training programs that will not harm the joints and hopefully it can result in fewer horses developing the disease”, says Eva Skiöldebrand.<br /><br /></div> <div><strong>Continued funding of the project</strong></div> <div>Moa Lord’s project &quot;Can we use saliva to detect osteoarthritis in the horse?&quot; has been part-financed by the Health Engineering Area of Advance at Chalmers. At the beginning of 2022, The Swedish Association for the Protection of Animals granted funding to investigate the presence of pain biomarkers in the saliva of horses. “The presence of pain biomarkers in saliva can provide an enormous amount of information about the horse's pain status and we are incredibly grateful for this research money”, says Eva Skiöldebrand.<br /><br /></div> <div>“The success of this research project is fantastically gratifying and hopeful for the diagnosis and prevention of osteoarthritis in horses, but also in humans in the future”, says Martin Fagerström, Co-Director of Health Engineering Area of Advance at Chalmers.<br /><br /></div> <div><strong>Joint commitment to horse welfare</strong></div> <div>The collaboration between Eva Skiöldebrand, SLU, and Magnus Karlsteen and Moa Lord at Chalmers has, among other things, its background in a common interest in equestrian sports and a strong commitment to horse welfare. Their paths have, among other things, been crossed at the Chalmers fence, an event in connection with the World Cup competitions in horse jumping in Gothenburg, with Magnus Karlsteen as responsible.</div> <div><br /></div> <div><strong>Reinforced focus on sports technology</strong></div> <div>According to the International Horse Sports Confederation, Chalmers is world leading in equestrian technology.<br /><span style="background-color:initial"><br />From 1 August 2022, Chalmers will be the first national sports university in Sweden to become a competence centre for sports technology.

Chalmers' test method is currently being used to produce balls for the World Cup.</b></p>​Shuttlecocks used in major competitions such as the Olympics and the World Cup have long been made of goose feathers. The aerodynamic properties have been considered superior to those shuttles made of synthetic material, especially in smash and net games, but that is changing. <h2 class="chalmersElement-H2">Challenges with traditional shuttlecocks </h2> <div>Shuttles made of goose feathers require a large amount of needlework and are made in Asia, often under doubtful working conditions. The feathers are harvested, cleaned and sorted according to length and angle, then they are fixed in a shuttlecock which is tested with many manual operations during all manufacturing steps. The shuttlecocks also require careful handling. They must be stored in regulated humidity and temperature to maintain their performance. Another problem is that they have a relatively short life in games. Manufacturers are now looking for alternatives with shuttles made of synthetic material. </div> <h2 class="chalmersElement-H2">Manufacturers in need of scientific tests </h2> <div>The test methods used for shuttlecocks uses professional players who have smashed the shuttlecocks a certain number of times and they have also tested games by the net to assess ball paths. The method works acceptably for shuttlecocks, but when synthetic balls were to be tested, one began to realize that the methods were too subjective. A more scientific approach was desired. </div> <div><br /> </div> <div><img class="chalmersPosition-FloatRight" alt="Christer Forsgren" src="/SiteCollectionImages/Institutioner/M2/Nyheter/Christer_Forsgren_170x220.jpg" style="margin:5px" />BWF started looking for solutions and talked to the company that tests shuttlecocks for them, Polyfor AB. It’s run by former elite player Christer Forsgren. He studied chemical engineering at Chalmers and has been active for seven years as an adjunct professor of industrial materials recycling at the Department of Chemistry and Chemical Engineering. Through his company, he has tested and approved balls for BWF for about 35 years. For Christer Forsgren, the contact with Chalmers was his first choice. </div> <div><br /> </div> <div>“Research in fluid dynamics and Chalmers' investment in sports technology is a good combination for developing test methods&quot; says Christer Forsgren. </div> <div><br /> </div> <div>The contact with Chalmers resulted in a research project that BWF decided to fund. </div> <h2 class="chalmersElement-H2">Tests in Chalmers’ Laboratory of Fluids and Thermal Sciences </h2> <div><img class="chalmersPosition-FloatRight" alt="Valery Chernoray" src="/SiteCollectionImages/Institutioner/M2/Nyheter/Valery%20Chernoray_I0A5484_170x170px.jpg" style="margin:5px" />Valery Chernoray is a research professor at the Department of Mechanics and Maritime Sciences and led the project with testing, that was performed by Satheesh Kaviladhikarakunnathu Puthanveeti, a former masters student at Chalmers. Valery says that they figured out and tested many different variants of test methods. They summarized everything in a report that BWF now uses to show that Chalmers' methods work, are objective and based on science and research. </div> <div><br /> </div> <div>“We have developed reliable methods for testing two performance characteristics that interest BWF. One is smash resistance or shot resistance which can be described as durability during repeated smashes and tumbling which is about performance in net games” says Valery Chernoray. </div> <div><br /> </div> <div>The rig built at Chalmers can simulate smashes up to 200 km / h. A professional racket is mounted on a carbon fibre arm that is driven by springs that are pulled up with a winch. The shuttles are held in place using a thin plastic tube and vacuum. The smashes are then filmed with a high-speed camera.</div> <div> </div> <div><img class="chalmersPosition-FloatRight" alt="​Shuttlecock and racket" src="/SiteCollectionImages/Institutioner/M2/Nyheter/badminton%20test.jpg" style="margin:5px;width:304px;height:231px" />&quot;With help from the films, we first check that the shuttle is smashed in a correct way and then we calculate the smashing speed. After each smash, we photograph the ball and measure how far the ball has flown to see if the damage to the ball has affected the performance. After ten smashes, the shuttles are packed and sent to RISE, Sweden’s research institute​, for material testing&quot; says Valery Chernoray. </div> <div><br /> </div> <div>For tumbling, they use a stationary ball and an angled racket that moves along an angled path. The test shuttles are filmed with a high-speed camera and the images are processed to calculate how many times the balls tumble. </div> <h2 class="chalmersElement-H2">The manufacturers work in the direction of synthetic shuttlecocks </h2> <div>All major manufacturers such as Yonex and Mizuno are now working intensively towards synthetic shuttles and the synthetic shuttles produced today are much better than a few years ago and are considered very good by both professional players and test teams. </div> <div><br /> </div> <div>“They are still a bit too fragile and can only handle two to four powerful smashes from the strongest elite players. But they could already be approved for, for example, Junior World Cup games” says Valery Chernoray. </div> <div><br /> </div> <div>Christer Forsgren explains the two shortcomings in today's synthetic shuttles. One is smash resistance. The shuttle becomes soft and does not return to its original shape fast enough, which is why it does not brake enough in the air for the smash to be returned. The second limitation is tumbling at nets. If the player hits the impact part, the cork, with the racket a little crooked, the shuttle can start to tumble, which makes it difficult to hit the shuttle towards the baseline with a controlled hit. But Christer Forsgren is hopeful that the synthetic shuttlecocks will be used. </div> <div><br /> </div> <div>“I'm a little doubtful about if there will be synthetic shuttles for the Olympics in Paris 2024, but I think there will be synthetic shuttles in the Olympics in Los Angeles 2028” says Christer Forsgren.​</div> <h2 class="chalmersElement-H2">Read more</h2> <div><a href="/en/departments/m2/news/Pages/The-world%27s-fastest-ball-game-to-become-synthetic.aspx">The world's fastest ball game to become synthetic​</a></div> <div><a href="/en/departments/m2/news/Pages/The-world%27s-fastest-ball-game-to-become-synthetic.aspx"></a><a href="/en/departments/m2/simulator-labs/labs/chalmerswindtunnels/Pages/default.aspx">Chalmers Laboratory of Fluids and Thermal Science​</a><br /><a href="/en/centres/sportstechnology/Pages/default.aspx">Chalmers Sports &amp; Technology​</a><br /></div>Tue, 13 Oct 2020 14:00:00 +0200 boat of cashews won in Italy<p><b>​Chalmers’ students continue to perform at the top in the student sailing competition 1001VelaCup in Italy. The regatta was cancelled this year due to Corona but was replaced with a design competition that Chalmers team won.</b></p>​Around 30 students from different grades and educational tracks have since the autumn semester 2019 been involved in the project of designing a racing boat with the final goal 1001VelaCup in Italy. Far into the spring, it was still uncertain whether there would be any sailing in Italy. The idea was to also build the boat, but then the news came. The regatta was cancelled and replaced with a design competition. <div><br /></div> <div>A total of 20 universities were invited to the competition. In competition with six other university teams from Germany and Italy, Chalmers' team submitted drawings, technical detailed descriptions, photos, information about construction processes and more, as well as a report of almost 200 pages. The submitted material was assessed on the three aspects innovation, thoroughness and presentation. </div> <h3 class="chalmersElement-H3">An extreme design </h3> <div>According to Lars Larsson, professor at Mechanics and Maritime Sciences and supervisor of Chalmers Formula Sailing, the construction was by far the most extreme construction in the competition. The boat sails on foils, which lift the hull out of the water. </div> <div><br /></div> <div>“The real challenge was to achieve stability in the flying condition. The boat becomes extremely unstable there. Through a newly developed method with separate flaps on the starboard and port sides and an advanced mechanical control system, the boat could be made as stable as without foils&quot; says Lars Larsson. </div> <div><br /></div> <div>The boat is built according to the R3 class rule which limits the boat in length, beam, sail area and that it must be naturally renewable or made of recyclable materials. In Chalmers' case, a high-performance dinghy for two sailors built from a bio-composite consisting of flax fibres, balsa wood and a thermoset plastics based on cashew nuts. </div> <h3 class="chalmersElement-H3">From start to finish </h3> <div>Chalmers Formula Sailing has been conducted within one of Chalmers' Tracks courses. This means that the students are given the conditions to create cross-border competencies according to their own wishes. Fabian Myrheim Ebbesson is in his final year of his master's degree in Naval Architecture and Ocean Engineering. He was Chalmers Formula Sailing's team leader and is very pleased with both the design and the training element. </div> <div><br /></div> <div>&quot;It feels very good to get the recognition from the judges of the 1001 Vela Cup. It’s a confirmation that our performance is of a high standard, not only in technical development but also in the presentation of the work performed. In this project, we had the opportunity to really get acquainted with a complex problem and drive the development from an idea to finished drawings&quot; says Fabian Myrheim Ebbesson. </div> <div><br /></div> <div>This was the third year Chalmers participated in the competition.

It is positive with less strain on the elbows, but otherwise it feels just as usual&quot;, she tells SVT Sport.<br /><br />The data from the handles is sent to software for analysis down to fractions of a single poling. It makes it possible to adjust the really small details of the ride. Lina Korsgren's trainer, former elite cyclist Mattias Reck, says on SVT Sport:<br /><div>&quot;Lina is already incredibly good, but that means if she is to get even better, there are little things you can work on.

Through the Area of Advance Materials Science and Chalmers Sports &amp; Technology he was given the opportunity to work with sensor solutions and underwater communication for swimming. The idea behind the ski power meter came as a spin-off from this work&quot;, says Dan Kuylenstierna.<br /><br />Johan Högstrand, who studied automation and mechatronics, was one of the students. The group ou students also included Henrik Gingsjö, Jeanette Malm, Theo Berglin, Mathias Tengström and Marcus Bengths.<br /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/dan_2015_350x305.jpg" alt="Photo of Dan Kuylenstierna." class="chalmersPosition-FloatRight" style="margin:5px" />After the end of the thesis work, the students continued to develop the handle with support from Vinnova. In 2017, they took the victory in the business development competition Chalmers Ventures Startup Camp. This helped them to establish the company Skisens AB, with Johan Högstrand as CEO. Dan Kuylenstierna is co-owner and co-founder:<br />&quot;With the large variations in the skiing conditions, power measurement is necessary to estimate performance. It is our conviction that in the long term it will be more important for skiiing than it currently is in cycling. The great importance of technical skills in cross-country skiing also makes it important to measure in the field under realistic conditions&quot;, says Dan (picture to the right).<br /><br />One who early snatched up the rumor about the company is the former coach of the Swedish national biathlon team (Svenska Skidskytteförbundet), Wolfgang Pichler. Pichler immediately said that &quot;power measurement is a revolution for skiing&quot; and got the team to invest in a collaboration with Skisens. Dan Kuylenstierna emphasizes the importance of this work and sees it as crucial for the company’s position today.<br />&quot;People like Wolfgang, who dare to invest in what is new even if the benefit lies several years into the future, are extremely valuable&quot;, he says.<br /><br />Now the company has arrived at a product that opens to a wider market with more partners. Recently, they have thus started to collaborate with Lina Korsgren's team, Team Ramudden, where Mattias Reck is hired as head coach via the company Guided Heroes.<br />&quot;It's very exciting to have the opportunity to apply my experience and knowledge in a new sport. In ski sports you often only have heart rate monitors, but with power meters in the sticks you can see how hard you press in every second, it gives completely new opportunities&quot;, says Mattias Reck in a press release.<br /><br />Dan Kuylenstierna is also Deputy Director of <a href="/en/centres/sportstechnology">Chalmers Sports &amp; Technology</a>, a venture that links academic research and sport in a number of projects. In the fall, he will lead the new course &quot;Digitalization in Sports&quot; within the framework of Chalmers new training venture <a href="">Tracks</a>, together with Moa Johansson at the Department of Computer Science and Engineering.<br />&quot;We have got 22 applicants who will work in groups of five on different challenges from the world of sports&quot;, concludes Dan Kuylenstierna.<br /><br />Text: Michael Nystås<br />Photo of Johan Högstrand and Lina Korsgren: Mattias Reck<br />Photo of Dan Kuylenstierna: Michael Nystås<br /><br /><strong>Contact:</strong><br />Dan Kuylenstierna, Associate Professor, Microwave Electronics Laboratory, Department of Microtechnology and Nanoscience – MC2, Chalmers University of Technology, <br /><br /><a href="">See the feature on SVT Sport</a> (in Swedish) &gt;&gt;&gt;<br /><br /><a href="">Read more about powermeters for cross-country skiing</a> &gt;&gt;&gt;Thu, 02 Jul 2020 10:00:00 +0200 Chalmers fence – five years of innovation<p><b>In a short time, Chalmers has become a leading part of the field of equestrian sports technology. In 2016, the Chalmers fence was launched during the annual Gothenburg Horse Show. Chalmers’ collaboration with the show has since then been about bringing theory and practice together, to decode the optimal jumping kinematics, and contribute with more sustainable horses and training methods.</b></p><div>Chalmers investment in equestrian sports technology has proven to be successful. The world of sport is always looking for new ideas and serves well as a testing arena for developing new technical solutions and materials. This research field is also giving Chalmers students the opportunity to combine leisure interests with studies.</div> <div> </div> <div><br /></div> <div> </div> <div>“The Chalmers fence is something the students work with in addition to their own studies, it is an opportunity to participate in a project that really makes a mark outside campus,” says Anna Karlsson-Bengtsson, Vice President of Education and Lifelong Learning at Chalmers University of Technology.</div> <div> </div> <h2 class="chalmersElement-H2">​​​<span>From idea to crowded arena</span></h2> <div> </div> <div>The Chalmers fence is a &quot;smart showjumping fence&quot; and every year a new technical solution is created to measure another kinematic aspect of the jumps. The results are presented to the large audience in Scandinavium on the jumbotron during the ongoing competition at the Gothenburg Horse Show.</div> <div> </div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/MagnusKarlsteen_textbild200x250.jpg" class="chalmersPosition-FloatLeft" alt="magnus karlsteen" style="margin:5px;width:150px;height:186px" />“I really want to point out that this project is the result of many enthusiasts' ideas and struggles. Many people at Chalmers have been involved over the years, not least horse-interested students,” says Magnus Karlsteen, adding that it is not only equestrian people involved in the projects. Many do it for the technical challenge and the community around it, says Magnus Karlsteen, who is responsible for the Chalmers Fence and Chalmers Equestrian sports projects.</div> <div> </div> <div><br /></div> <div> </div> <div>Magnus Karlsteen went to riding school for one summer as a 6-year-old, but he &quot;has hardly ever seen a horse since then&quot;. Nevertheless, Chalmers’ research into equestrian sports has attracted considerable attention in the equestrian world, which is much larger than most people can imagine. According to the Swedish Equestrian Federation, half a million Swedes are involved in the sport and it is Sweden's third largest youth sport (for 7–25-year olds). There is a significant equestrian sports industry with everything from suppliers of horse feed and veterinarians to product developers and trainers.</div> <div><br /></div> <div> </div> <div>Chalmers often organises public seminars, where different stakeholders are invited to share the latest in different research areas. When the first meeting regarding equestrian sports was organised in 2012, it turned out that the demand for research within the field was enormous.</div> <div><br /></div> <div> </div> <div>“At a certain equestrian technology meeting we received several hundred interested people. The interest was almost as great as when the Nobel laureates visits campus,” says Magnus Karlsteen.</div> <div><br /></div> <div> </div> <div>A few years later, in 2015, Chalmers met representatives from Gothenburg Horse Show for the first time and the Chalmers fence, which was originally initiated by the former Vice President Maria Knutson-Wedel, began to grow from idea to reality.</div> <div> </div> <div><br /></div> <div> </div> <div>“The collaboration with Chalmers is part of Gothenburg Horse Show's work to support development. Equestrian sport has been given new scientific information which supports our work on horse training and competition”, says Tomas Torgersen, director for the Gothenburg Horse Show.<span style="background-color:initial"> </span></div> <div> </div> <h2 class="chalmersElement-H2">Opportunity to combine interests with studies</h2> <div> </div> <div>Although the investment has only been going for five years, there are already examples of horse-interested Chalmers students who have gained interest in the engineering profession after seeing the Chalmers fence and visiting Chalmers’ booth during the competition in Scandinavium.</div> <div> </div> <div><br /></div> <div> </div> <div>Chalmers student Anna Skötte, project manager for the fence group 2020, is interested in both horses and technology and thinks that the Chalmers fence shows how well it works to combine these two interests.<img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/Annaskotte_textbild_hinder.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:200px;height:196px" /><br /><br /></div> <div> </div> <div><span style="background-color:initial">“</span><span style="background-color:initial">The days we spent in Scandinavium were extremely exciting, even though they also were very busy. The most fun thing was that everyone involved and even the audience experienced the fence measurements as interesting and successful! Also, the fact that I got to know so many different people both from Chalmers and the outside world has been very valuable,” says Anna Skötte.</span></div> <div> </div> <h2 class="chalmersElement-H2">​&quot;We forgot that horses have tails”</h2> <div> </div> <div>Technical problems and time issues are a part of the everyday life of an engineer, something that the Chalmers students who have been involved in the Chalmers fence have gained practical experience of. </div> <div><br /></div> <div>Magnus Karlsteen talks about one of the most memorable incidents over the years. During a test run a few days before the show, the participating horse had an unusually long tail. The fence had been jumped before and everything had worked well, but now the technology caught the lowest point of the tail, instead of the hooves, as the measuring point over the fence. In the computer, it looked like every bar was falling down, when in reality it was only hairs from the tail that rubbed the bars.</div> <div><br /></div> <div> </div> <div>“It was eventually solved by having students manually reviewing each point of the kinematics before the results were posted on the jumbotron in the arena. It is an example of what a good training in problem-solving the project gives the students – they get an invaluable experience of real working life,” says Magnus Karlsteen.</div> <div> </div> <h2 class="chalmersElement-H2">Old truths questioned through new knowledge</h2> <div> </div> <div>The Chalmers fence has questioned a long-lived myth in the world of equestrian sport. The old truth says that the horse's takeoff point  is as far ahead of the fence as the fence is high. But when the students' results of the Chalmers fence in 2017 were analysed by Chalmers researcher Kristina Wärmefjord, it was confirmed that the horses jump off considerably further away than that. There is even a formula for this, which reads &quot;1.3x obstacle height + 0.2&quot;. The measurements showed that on a 1.50 fence, the horse's hooves are on average 2.15 meters from the fence in the take-off.</div> <div> </div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/Chalmershindret_200x250px.jpg" alt="showjumping" class="chalmersPosition-FloatLeft" style="margin:5px" />The results from Gothenburg Horse Show have over the years also confirmed knowledge that previously was mostly based on the riders' gut feeling, for example that more experienced horses and riders manage to maintain a more even rhythm and speed – before, over and after the fence. In classes with young riders or young horses, the numbers were much more varied than in the world elite jumping classes.</div> <div> </div> <div>Worldwide interest </div> <div> </div> <div><br /></div> <div> </div> <div>Chalmers has collaborations with several stakeholders both in Sweden and abroad regarding equestrian sport technology. There are collaborations with the Swedish breeding association SWB, and research applications are in progress together with the International equestrian committee, Fédération Équestre Internationale (FEI). There is also a collaboration with Sahlgrenska University Hospital and with the Swedish University of Agricultural Sciences (SLU). During the European Championships in Gothenburg 2017, Chalmers students also participated in the production of obstacles for the competitions in driving, and through a design competition Chalmers students developed no less than four of the jump fences at the Ullevi stadium. There are also examples of Chalmers projects in trotting and horse racing.</div> <div> </div> <div><br /></div> <div> </div> <div>A collaboration with the Swedish School of Textiles in Borås has resulted in development of the possibility to measure ECG, heart rate and breathing with smart textiles through the horses’ fur – the list of impacts in different areas can be long. Chalmers’ equestrian technology has established contacts within equine research in Australia. Among other things, several students were invited to present their horse racing project in the Australian city of Wagga Wagga in 2018.</div> <div> </div> <div><br /></div> <div> </div> <div>“The students are given a unique opportunity to create a network – internally at Chalmers, in the corporate world, in the horse sector and in various research areas around the world. We are constantly contacted by new stakeholders,” says Magnus Karlsteen.</div> <div> </div> <div><br /></div> <div> </div> <p class="chalmersElement-P">Ireland is another great horse nation that has shown interest in Chalmers’ equestrian technology. During Gothenburg Horse Show this year, the fence group was contacted by the head of the Ireland national team. The Chal​mers students received an invitation to visit Ireland and set up the Chalmers fence at the prestigious Dublin Horse Show in the summer of 2020 – though the collaboration has unfortunately been postponed due to the coronavirus crisis. <span style="background-color:initial;color:rgb(51, 51, 51)"> </span></p> <p></p> <p class="chalmersElement-P"> </p> <div><h2 class="chalmersElement-H2"><span>The next step: </span><span>comme</span><span>rcialisation</span><span></span><span> and entrepreneurship</span></h2></div> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The work of taking the technology from the Chalmers fence to the next step in a commercialisation process is done in various ways, including, in the spring of 2020, a master’s thesis titled &quot;Development and testing of a concept for analyzing kinematics in show jumping&quot;.</p> <div> </div> <div><br /></div> <div> </div> <div>“We believe that video analysis is a way forward for equestrian sport technology.

In previous years, the Chalmers fence has measured one variable at a time.

The Chalmers Formula Sailing team has built the boat of 70 % organic material, and at the end of September, the students went to Palermo, Sicily to participate in the sailing competition. Their participation was possible thanks to funding from the Chalmers University of Technology Foundation.</p> <p style="text-align:left">Besides the team from Chalmers, the competition consisted of student teams from seven Italian universities and one German, all of which have built boats with the same restrictions regarding material. During six races, two elite level sailors in the Olympic 49er class, Fritiof Hedström and Otto Hamel, who are students at Chalmers, sailed the unique boat. </p></div></div> <p>“It is an extreme boat”, says Lars Larsson, Professor of Marine Technology and supervisor of Chalmers Formula Sailing. “It has a large sail plan for its size, and most people who would try to sail it would capsize immediately.

One of the races suddenly became quite dramatic when the boat’s tiller broke.

Adam Persson, PhD student, has been the group's supervisor throughout the project, from creating the design to completing the boat.

That’s what eight students at Chalmers are working with this winter. Formula Sailing is a boat building project where 70 percent of the boat core has to be made of biomaterials. In September they will compete in Italy – and during ‘Båtmässan’ they will display the dinghy.</b></p><p>​Since August last year, the students have been designing and building the unusual race dinghy. All the boat builders are all students at the master’s programme Naval Architecture, after studying mechanical engineering their first three years at Chalmers.In an on-campus workshop, the students are laminating the balsa wood boat core with flax and cashew nut based epoxy. Erik Ericsson, one of the students in the project, has been in charge of choosing materials.<br />– We have chosen a core that is a softer and weaker material, balsa wood. And on each side of that core you have a laminate with several layers of flax/bioepoxy. That provides structure with stiffness and strength, says Eriksson. <br />– Epoxy is basically a form a glue that glues together the flax fibers with the core, says Simon Granli who’s also a part of the project group. <br />Eric Eriksson admits the chosen lamination won’t be as good as carbon fiber or glass fiber would be – but those are materials the rules of the competition won’t allow them to use. Based on the flax/cashew nut epoxy’s stiffness to its weight ratio, it’s one of the best possible choices from the organic world. <br />– The weight is important! The less the dinghy weighs, the faster is goes, says Granli. </p> <p><br /></p> <p><strong>Competing in Italy this fall</strong><br />Each year, boats representing universities all over the world compete in a three-day race. Last year, the competition was held in Palermo in September. The two main supervisors at Chalmers then attended the races to see and learn. Most likely the venue will be the same in 2018 and the time will again be late September. <br />During the summer, the Chalmers students will practice sailing the dinghy, and prepare for the competition. The rules state that the sailor of the boat must be a student from the same university as the design and building team, and the recruitment of this person who will be sailing is under way at the time of writing.<br /><br /><strong>Exhibition at Båtmässan</strong></p> <p>From the 3rd to 11th of February, Chalmers Formula Sailing will be exhibiting the sail dinghy at the boat fair, Båtmässan, at Svenska Mässan in Gothenburg, in booth number F04:21 (GKSS).</p> <p><br />See the <a href="">video</a></p> <p>Read more about the <a href="/en/centres/sportstechnology/research/sports/sailing/Pages/Formula-Sailing.aspx">Chalmers Formula Sailing project</a></p> <p><span id="ms-rterangepaste-end" style="display:inline-block"><br /></span></p> <strong>FACTS ABOUT THE COMPETITION:</strong><br />Conceive, Design, Implement and Operate are the keywords of the innovative so called CDIO initiative, where the student competition Formula Sailing is included.

Chalmers and SSPA wanted the challenge to do this on “the world´s least advanced sailboat” – the optimist dinghy. The main question and problem for the students and the researchers of this project has been: can an optimist foil and how will this be done? <br /> <br />The optimist dinghy has, since it was conceived in 1947, become one of the world’s most popular sailing dinghies, with over 150 000 boats registered. The boat, only 2.3 metres in length and with a sail area of 3.3 square metres, is normally limited to speeds below 4 knots. <br /> <br />However, by building the boat in carbon fibre and graphene, and fitting it with hydrofoils lifting the hull out of the water, the hydrodynamic resistance can be reduced dramatically. <br /> <br />The hydrofoils, constructed and tested at SSPA, allowed the optimist dinghy to sail as fast as the wind in the recently conducted sea trials, achieving a maximum boat speed of 12 knots in only 12 knots of wind.<br /><br />Watch a video about <a href="">the premiere of the foiling optimist</a><br /><br /><strong>For more information, please contact:</strong><br />Christian Finnsgård, +46- 31 772 9156, mobile +46-730729156, <a href=""></a>Fri, 07 Apr 2017 00:00:00 +0200 horses contribute to research in physics<p><b>Recently, fifteen police horses in Gothenburg have contributed to science. They have supported the development of a new method to detect damages in the hooves by using thermoelectric sensors. In the future, hopefully, this technique can be an attractive alternative to other diagnostic tools, for example X-rays. </b></p><div>​“Some injuries in the hoof capsule of the horses can be difficult to detect, for example cracks or infections in the tissue between the hoof wall and the hoof bone. By measuring the heat transport in the hoof it might be possible to detect damages that cannot be observed in other ways”, says Jennie Sköld, Master's student of science engineering physics at Chalmers.<br /><img class="chalmersPosition-FloatRight" alt="sensorer_satts_pa_hasten_170x270_IMG_0038.jpg" src="/en/departments/physics/news/Documents/sensorer_satts_pa_hasten_170x270_IMG_0038.jpg" style="margin:5px" />In this research project she combines two of her major interests: physics and horses. She temporarily moved from Värmland to Gothenburg to fulfill this dream. Together with team members from Chalmers Sports and Technology, University of <span>Gothenburg <span style="display:inline-block"></span></span>and different collaborators from the industry she is making the first studies on live horses.</div> <div>“It’s nice to be part of such a diverse team with unique competence. My experience with horses has really helped me a lot – it’s not necessarily easy to put sensors, wires and equipment on a horse and convince it to stand still”, says Jennie Sköld, scratching today’s collaborator – Viggo – on the back. </div> <div> </div> <div>The horse accepts the procedure, rests his head on the shoulder of his friend and farrier, Björn Berg, and enjoys the candy that he gets from Åsa Hinton, the project’s veterinary. </div> <div> “This is totally harmless for the horse. If this method works out the way we hope it will, hopefully we can detect a stress reaction in the hoof capsule before the problem gets too severe.

The sensors are developed by a spin-off company from Chalmers – Hot Disk <span> – </span>and the application for horses is brand new. To develop it and make it more user friendly they are working on a prototype that can <span>easily <span style="display:inline-block"></span></span>be put on the hoof.</div> <div> </div> <div>After more than 40 hours in close cooperation with the horses, Jennie Sköld and her supervisor Besira Mekonnen Mihiretie, start to see patterns of how a signal from a healthy hoof capsule looks. In the future the patience of the police horses might help other horses to stay in good health. </div> <div> </div> <div><img class="chalmersPosition-FloatRight" alt="Jennie_Susanne_Viggo_340x296_IMG_0091.jpg" src="/en/departments/physics/news/Documents/Jennie_Susanne_Viggo_340x296_IMG_0091.jpg" style="margin:5px" />The horses in the police cavalry in Gothenburg have been selected for various reasons. They are healthy, held and trained in the same way, most of them are of the same breed and they have the same farrier.<br /></div> <div>“On top of that they are used to strange things, but to take part in a research project is a completely new experience. Of course we want to support this”, says Susanne Johansson, division manager at the police cavalry in Göteborg. </div> <div> </div> <div>“I really hope that this results in a better way for farriers and veterinaries to take care of the horses”, says Jennie Sköld.</div> <div> </div> <div>Text: Mia Halleröd Palmgren,</div> <div> </div> <h4 class="chalmersElement-H4">About the research</h4> <div><img class="chalmersPosition-FloatLeft" alt="sensorer_270x170_IMG_0110.jpg" src="/en/departments/physics/news/Documents/sensorer_270x170_IMG_0110.jpg" height="134" width="214" style="margin:5px" />A non-invasive method for the detection of damage and changes in equine hoof walls.
