Lina Korsgren has now started to use the invention in her training:<br />&quot;The handle is a little thicker than a regular handle, but I just see it as an advantage because then you do not have to hold the pole as hard. 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. Power measurement is really such a next step. I am absolutely convinced that we will make her even stronger.&quot;</div> <div><br /></div> <div><br /><br /></div> <div><span><em><br />Johan Högstrand, CEO of Skisens AB, and skier Lina Korsgren </em><br /><em>with the ski poles whose handle is based on Chalmers </em><br /><em>technology. Photo: Mattias Reck</em></span><br /></div> <br />The background to the handle is a master's thesis, which was supervised in 2016 by Dan Kuylenstierna, associate professor at the Microwave Electronics Laboratory at the Department of Microtechnology and Nanoscience – MC2 – at Chalmers, and postdoctoral student Szhau Lai at the same department.<br />&quot;Szhau Lai, who had recently defended his thesis, showed a keen interest in sensors and embedded electronics. 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="https://student.portal.chalmers.se/en/chalmersstudies/tracks">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, dan.kuylenstierna@chalmers.se <br /><br /><a href="https://www.svt.se/sport/langdskidor/vasaloppsvinnaren-tar-hjalp-av-ny-teknik">See the feature on SVT Sport</a> (in Swedish) &gt;&gt;&gt;<br /><br /><a href="https://skisens.se/en-produkten">Read more about powermeters for cross-country skiing</a> &gt;&gt;&gt;Thu, 02 Jul 2020 10:00:00 +0200https://www.chalmers.se/en/news/Pages/five-years-with-the-chalmers-fence.aspxhttps://www.chalmers.se/en/news/Pages/five-years-with-the-chalmers-fence.aspxThe 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. We want to be able to offer riders and trainers a static tool that with the help of collected data, could detect a downward trend in the horse's performance at an early stage, which could be an indication of an injury for example. By quickly identifying a negative signal, the horse's well-being and a possible veterinary cost can be positively affected,” says Elin Lorin, one of the students behind the study.</div> <div> </div> <div><br /></div> <div> </div> <div>She and her fellow student Niklas Westman are now getting help from Chalmers Innovation Office to develop the Master thesis into an eventual Startup. Several students who have been active in the Chalmers fence group are today entrepreneurs within the field.</div> <div> </div> <div><br /></div> <div> </div> <div>The technical aspects of the Chalmers fence are also being developed within the Chalmers educational investment Tracks.

As the Chalmers fence now celebrates its five-year anniversary, two new steps are taken – the technology used will for the first time be based on machine learning, and the previous measurement technology from the fence will move into the Swedish Equestrian Federation&#39;s educational facility Strömsholm.</b></p>​<span style="background-color:initial">The way a horse jumps over a fence differs between both individuals and equipage. Some horses jump off too early or too late, giving the highest point before or after the fence. In an optimal jump, the highest point is just above the fence, meaning the horse used just the right technique and amount of energy for its leap.</span><div><br /></div> <div><strong>First time with machine learning</strong><br /><span style="background-color:initial"></span><div>For this year's fence, the group of students will, for the first time ever, use the Image Processing technique, where a computer is trained through machine learning to detect the horse's hooves in a filmed leap and thereby calculate the coordinates for the highest position in the jump over the fence.</div> <div><br /></div> <div>“This involves some technical difficulties. In previous years, the Chalmers fence has measured one variable at a time. We are measuring both the highest point in a vertical path from the ground, and where that point relates to the fence in a horizontal direction,” says Anna Skötte, student and project manager for the Chalmers fence 2020.</div> <div><br /></div> <div>The Chalmers fence project is run by Chalmers students in collaboration with Gothenburg Horse Show, with the aim of using new smart technology to broaden the knowledge of the horses' jumping technique and thereby provide scientific evidence for sustainable training and competition of horses, as well as breeding. Like last year, the competing riders in the Gothenburg Horse Show are invited to the Chalmers exhibition stand in Scandinavium's foyer to see their own measuring results.</div> <div><br /></div> <div><strong>Swedish Equestrian Federation will use the technology​</strong></div> <div>The Chalmers fence project takes yet another new and important step as the combined experience from five years of measurements at the Gothenburg Horse Show will moves into the Swedish Equestrian Federation's riding house Strömsholm. The national team leaders in the Equestrian Association Federation have made a wish list for more developed scientific technology, and Chalmers University of Technology has been asked to engage, together with the Swedish University of Agricultural Sciences and the National Horse Industry, and further develop the connected riding house at Strömsholm and supplement with cameras and sensors for biomechanics, among other things.</div> <div><br /></div> <div><strong>What does this collaboration mean for the equine industry and equestrian sports in Sweden?</strong></div> <div>“In the horse world we have a lot of commonly accepted truths that we have not been able to test scientifically.

With the boat Linnea, built with a balsa wood core with flax and a cashew nut-based epoxy, the team won the entire competition in Palermo, Sicily.</b></p><div dir="ltr"><div dir="ltr"><p style="text-align:left">​Since August last year, masters students from the Naval Architecture and Ocean Engineering program have not only designed and built the sailing dinghy Linnea, but also made all the analyses and calculations that underlie the boat. 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. The boat would probably overturn from just lying unmanned in the water.”</p> <p></p> <h4 class="chalmersElement-H4">Dramatic competition</h4> <p></p> <p>The Chalmers Formula Sailing team managed to hold top positions throughout the competition. One of the races suddenly became quite dramatic when the boat’s tiller broke. Lars explains that it did not withstand a hit from above and that it was due to a construction flaw. </p> <p>“To sail without a tiller is virtually impossible, but Fritiof laid down across the aft and steered the rudder – which is very heavy and hard to turn – using only his hands. The sailors still managed to score third in the race. You could really tell that they are elite sailors!”</p> <p>Fortunately, the team managed to fix the tiller over the night, just in time for the next race and all in all they won the entire competition. Adam Persson, PhD student, has been the group's supervisor throughout the project, from creating the design to completing the boat. He explains how they won first place.</p> <p>“The boat is built to be as adapted as possible to the wind conditions where we were going to sail. Together with talented sailors, we were faster than the other teams.” </p> <p></p> <p></p> <p></p> <h4 class="chalmersElement-H4">The team is looking forward</h4> <div>The win, he says, was celebrated traditionally by throwing the crew in the pool. Adam continues to say that the competition feels very successful and that the point of a contest like this is getting to compare with other universities and to continuously raise the bar.</div> <p></p> <p>“The win is really a testament to the hard work we put into this project. It shows that with an engineering approach you can make a very good boat. We are of course very pleased with the sailing and we can’t wait for next year’s competition.”</p> <p><br /></p> <p>Read more: <a href="/en/news/Pages/Organic-boat-building.aspx">&quot;Organic boat building in a nutshell&quot;</a>. </p> <p>Learn more about the <a href="/en/centres/sportstechnology/research/sports/sailing/Pages/Formula-Sailing.aspx">project Chalmers Formula Sailing</a>.</p> <p>Learn more about Chalmers investment in sports technology, <a href="/en/centres/sportstechnology/Pages/default.aspx">Chalmers Sports &amp; Technology</a>.<br /></p> <p><br /></p> <p><strong>Text:</strong> Sophia Kristensson<br /></p>Tue, 25 Sep 2018 14:00:00 +0200https://www.chalmers.se/en/news/Pages/Organic-boat-building.aspxhttps://www.chalmers.se/en/news/Pages/Organic-boat-building.aspxOrganic boat building in a nutshell<p><b>​A dinghy with a core made of balsa wood, flax and a cashew nut based epoxy. 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="https://www.youtube.com/watch?v=XZWEhMJZuNU">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.

By using a carbon fibre  composite with added graphene, the hull is made stronger and lighter. Hydrofoils are added to lift the boat, decreasing drag and allowing greater speeds. After tests performed in SSPAs towing tank, the dinghy was ready to be tried out at sea for the first time.</b></p>​A relatively new occurrence within the sailing world is to mount hydrofoils on small sailing dinghies. 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="https://www.youtube.com/watch?v=UokOO60dsMU">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="mailto:christian.finnsgard@chalmers.se">christian.finnsgard@chalmers.se</a>Fri, 07 Apr 2017 00:00:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/-Police-horses-contribute-to-research-in-physics.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/-Police-horses-contribute-to-research-in-physics.aspxPolice 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. In some cases, i<span><img class="chalmersPosition-FloatLeft" alt="Jennie_Björn_Åsa_Vigo_270x170_IMG_0045.jpg" src="/en/departments/physics/news/Documents/Jennie_Björn_Åsa_Vigo_270x170_IMG_0045.jpg" height="187" width="298" style="margin:5px" /></span>t might be possible to decrease the area of surgery, since we could know the extent of the defected area”, says Åsa Hinton.  </div> <div>The <span>thermoelectric <span style="display:inline-block"></span></span>sensors attached to the hooves measure the thermal conductivity and makes it possible to see the structure of a healthy hoof capsule. 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, mia.hallerodpalmgren@chalmers.se</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.
