News: Signaler och system related to Chalmers University of TechnologyMon, 03 Jul 2017 11:34:00 +0200 that takes research across boundaries<p><b>​It takes cross-disciplinary collaboration to solve the research challenges of the future. In an initiative from the new Electrical Engineering department, the teams behind six promising, pioneering research projects  that reach across organisational boundaries have now been given the opportunity to take their plans forward.</b></p><div>​The management group of the department of Signals and Systems (S2) devised this initiative in autumn 2016. On 1 May this department is being merged with the Electric Power Engineering and High Voltage Engineering divisions to form the department of Electrical Engineering (E2). This initiative has a long-term focus and will continue as a strategic project until 2019.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ett%20initiativ%20som%20tar%20forskningen%20över%20gränserna/Anders_Karlstrom_DSC_3415_300px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Anders Karlström, Head of Department, says: “We have a lot to gain from thinking outside divisional and departmental boundaries. It’s just the first step towards what I hope will be an ongoing process of encouraging new research initiatives.”</div> <div> </div> <div>There was a good response to the call for proposals that went out at the beginning of the year. No less than eleven project concepts were submitted. After assessment, six were selected and were allocated an internal grant of SEK 0.5 million each, for use during 2017.</div> <div> </div> <div>Karlström continues: “The project proposals are highly promising and of a high quality, so we decided to accept more of them than we had intended at the outset. The idea is that the researchers have six months’ funding to enable them to produce results that are interesting enough that they can then seek external funding for further development work on the projects. Another objective is for this initiative to work as a catalyst for a new way of working and thus enhance integration within the new department.” </div> <div> </div> <div>Preparations are already under way for the new call for proposals in September, for the next cross-boundary project in 2018. </div> <div> </div> <div>“It will be exciting to see the proposals. The researchers’ creativity in putting forward cross-boundary initiatives has so far exceeded my expectations,” he says.</div> <div> </div> <h4 class="chalmersElement-H4">Communications technology provides medical benefits</h4> <div>Thomas Eriksson (Communication Systems) and Christian Fager (Microwave Electronics at MC2) have collaborated for many years in the communication field. Eriksson’s research is geared to signal processing and communications whereas Fager focuses on the hardware side, specialising in areas such as circuit design and measurement techniques. When the call for proposals went out at the beginning of the year they firmed up their previously rather vague plans to expand their area of research to the field of medicine. Eriksson and Fager joined forces with Andreas Fhager, a researcher in biomedical electromagnetics, to submit a project proposal combining their respective specialist fields. <br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ett%20initiativ%20som%20tar%20forskningen%20över%20gränserna/kollage.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><br /></div> <div><br /><br /><br /><em>Andreas Fhager, Thomas Eriksson and Christian Fager are starting a cooperation between medical engineering and communications technology.</em><br /><br />&quot;If we transfer established technology from the communication field to the technology platform we are using in the medical research area, this may open the door to a number of exciting new applications,” says Andreas Fhager. “I also see significant advantages from gaining access to systems that are faster, smaller, cheaper and lighter.&quot; <br /><br /></div> <div>“We are aiming to reduce the measuring time and improve the calibration technology for microwave measurements. For instance, we use what are known as Stroke Finder helmets which help to diagnose stroke patients,” says Thomas Eriksson. “As a result of our experiences in the communication field we believe it is possible to perform real-time measurements if we develop the measuring equipment by using several rapid wideband antennas.”<br /><br /></div> <div>Such rapid and reliable microwave measurements could be used to monitor a patient’s pulsating heartbeat, for example. If the technology could also be simplified to such an extent that it could be provided in medical centres and ambulances, this would bring significant advantages in diagnosing patients and assessing the medical care they require. <br /><br /></div> <div>“Applying your research to a new field, which is also so close to people and where there is a clear link to the benefits for the patient, is an enjoyable and exciting challenge”, says Christian Fager. <br /><br /></div> <div>“It’s also important for us to have the opportunity to learn from one another and enhance our understanding of our respective research fields. We represent three strong research teams at Chalmers and by joining forces we have the potential to develop something really good,” he stresses.<br /><br /></div> <div>The project is a long-term one but it needs initial help in order to establish a concept for further work. The plan is to use the funds in 2017 for a temporary post-doctoral appointment to allow a simple demonstration of the technology to be carried out. The project team believes there is a good chance of producing results fairly rapidly, which would then allow it to take the project forward with external funding.</div> <div> </div>Thu, 27 Apr 2017 12:00:00 +0200 project on imaging biomarkers for drug safety assessments<p><b>​The Innovative Medicines Initiative (IMI) has approved the 5-year project TRISTAN focusing on validation of translational imaging methods as potential imaging biomarkers.</b></p>​<span><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/New%20project%20on%20imaging%20techniques%20in%20drug%20safety%20assessment/tristan_300px.jpg" alt="" style="margin:5px" /></span>TRISTAN (Translational Imaging in Drug Safety Assessment) is a public-private partnership supported by the Innovative Medicines Initiative (IMI) and involving 21 organisations including academics centres, research organisations, small and mediumsize enterprises (SMEs), imaging and pharmaceutical companies.<br /><br />TRISTAN is a significant investment in imaging research in West Sweden. Other West Sweden collaborators in addition to Chalmers include Västra Götalands Region, Sahlgrenska Academy and Antaros Medical, who are all working to avoid toxicity in humans during drug development.<br /><br />The objective of the project is to validate or qualify translational imaging methods as potential imaging biomarkers. The imaging biomarker qualification will be specifically addressed in three areas with a high unmet medical need: the assessment of liver toxicity, lung toxicity and the bio-distribution of biologics. The in-kind contributions to the project of around EUR 12 million by the industrial partners are complemented by IMI-funding in a total budget of EUR 24 million. TRISTAN is led by Bayer and coordinated by the European Organisation for Research and Treatment of Cancer (EORTC), who also leads one imaging biomarker qualification study for cancer drug induced interstitial lung disease. <br /><br />Imaging techniques are firm components of today’s medical practices, just as the use of biomarkers has become commonplace in pre-clinical and clinical research. However, imaging biomarkers are not widely used in the drug discovery process although they could advance drug safety evaluation, both for pre-clinical and clinical development. Imaging biomarkers have the potential to improve translatability of pre-clinical (animal) data to healthy volunteers and patients and thus could help avoid late stage attrition of development programmes. In addition, functional diagnostic imaging methods used as biomarkers would offer the possibility to confirm drug toxicity mechanisms in humans, including the potential to determine drug-drug interactions. <br /> <br />Data relevant for validation of methods addressed in the project and aggregated data will be made publicly available in compliance with data privacy laws. Significant interactions with existing imaging biomarker initiatives as well as with regulatory authorities will have a strong impact on the future value of imaging biomarker procedures. To sustainably offer access to the validated imaging biomarkers, the three project SME partners are planning to offer respective biomarker imaging services commercially. <br /><br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/New%20project%20on%20imaging%20techniques%20in%20drug%20safety%20assessment/Tristan_IMG_7682_340px.jpg" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><em>“We are very proud of being a partner in the TRISTAN consortium and that our MRI-models are used to find biomarkers to better predict toxicity in humans in drug development&quot;, says Paul Hockings, Adjunct Professor at Chalmers University of Technology and at MedTech West</em><em>, and Per Malmberg, researcher in Analytical Chemistry at Chalmers University of Technology.</em><br /> <br /><strong>About Imaging Biomarkers </strong><br />An imaging biomarker is a functional radiographic imaging procedure utilising imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Positron Emission Tomography (PET). In research and development, imaging biomarkers are used as characteristics to objectively measure biological processes, pathological changes, or pharmaceutical responses to a therapeutic intervention. They have the advantage of remaining non-invasive and being spatially and temporally resolved. Imaging biomarkers have the potential to improve translatability of animal data to healthy volunteers and patients, thereby helping to improve our understanding of drug mechanisms, interactions and metabolic processes. <br /><br /><strong>About the Innovative Medicines Initiative (IMI) </strong><br />The Innovative Medicines Initiative (IMI) is working to improve health by speeding up the development of, and patient access to, innovative medicines, particularly in areas where there is an unmet medical or social need. It does this by facilitating collaboration between the key players involved in healthcare research, including universities, the pharmaceutical and other industries, small and medium-sized enterprises (SMEs), patient organisations, and medicines regulators. IMI is a partnership between the European Union and the European pharmaceutical industries, represented by the European Federation of Pharmaceutical Industries and Associations (EFPIA). Through the IMI 2 programme, IMI has a budget of EUR 3.3 billion for the period 2014-2024. Half of this comes from the EU’s research and innovation programme, Horizon 2020. The other half comes from large companies, mostly from the pharmaceutical sector; these do not receive any EU funding, but contribute to the projects ‘in kind’, for example by donating their researchers’ time or providing access to research facilities or resources. <br /><br />The research leading to these results received funding from the Innovative Medicines Initiatives 2 Joint Undertaking under grant agreement No 116106.

This sound transmission through bones is an important part of osseoperception – sensory awareness of the patient’s surroundings provided by their prosthesis. This discovery sheds new light on the tactile and auditory perception of humans and can be used to develop improved prostheses.</b></p>​How can we help amputees regain tactile sensations and other natural feelings while grasping an object or walking on uneven ground?<br /><br />An international group of researchers in Sweden and Italy offers a new answer. They have demonstrated for the first time that patients with implanted osseointegrated prostheses (ones attached directly to the skeleton) are able to perceive external stimuli better by hearing through their limb implants.<br /><br />The investigation was conducted jointly in Sweden by Chalmers University of Technology, Sahlgrenska University Hospital, and the University of Gothenburg; all collaborating closely with Scuola Superiore Sant’Anna in Italy.<br /><br />In a recent paper in <em>Nature Scientific Reports,</em> the researchers presented a discovery that opens up new scenarios for developing novel artificial limbs. Even though the transmission of sound through skull bones is a well-known phenomenon, widely studied by Professor Bo Håkansson at Chalmers who was a participant in this study, it was not clear whether this also occurs through bones in the arms and legs and thus contribute to osseoperception – “feeling” arising from the mechanical stimulation of an osseointegrated prosthesis.<br /><br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Hearing%20and%20touch%20mediate%20sensations%20via%20osseointegrated%20prostheses/Max-Ortiz-Catalan_S8A7544-1_180px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br />“Until now, the consensus was that the sense of touch played the primary role in osseoperception for patients with artificial limbs fixated into their skeletons”, says Max Ortiz Catalan, head of the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers and supervisor of the research.<br /><br /><br /><br />Francesco Clemente, who conducted the experiments as a visiting PhD student at BNL from the Biorobotics Institute of Scuola Superiore Sant’Anna, comments:<br /><br />“Using four different psychophysical tests, we have demonstrated that even subtle sensory stimuli can travel through the body and be perceived as sound. This hearing increases the individual’s sensory awareness, even in patients with osseointegrated implants in their legs.”<br /><br />These results show that osseointegration, which allows for stable mechanical attachment of robotic prostheses directly to the skeleton through a titanium implant, improves patients’ functionality, comfort, and ability to perceive the world around them.<br /><br />The researchers tested twelve patients with various degrees of amputation, both upper and lower limb amputees. All tests indicated that patients could perceive mechanical vibrations applied to their titanium implants, through hearing as well as touch. In particular, and synchronously with the vibrations in their arms or legs, patients reported audible sound. During the experiments, the researchers found that subjects with osseointegrated prostheses could perceive very small stimuli and react more quickly to them due to additional perception by hearing.<br /><br />“In practice, the stimuli received by the patients are perceived more strongly and carry more information because they are composed of two modalities; touch and hearing,” says Max Ortiz Catalan. “This is an important step forward in understanding the osseoperception phenomenon and, more generally, the tactile and auditory perception of humans. This discovery may offer a new starting point for implementing novel prostheses that provide enriched sensory feedback to the user.”<br /><br />Read the article in <span><em>Nature Scientific Reports:<br /><span style="display:inline-block"></span></em></span><span></span><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Touch and Hearing Mediate Osseoperception</a><br /><br /><strong>For more information, please contact:</strong><br />Max Ortiz Catalan, Department of Signals and Systems, Chalmers University of Technology, Sweden.<br />Tel: +46 70 846 10 65, <a href=""></a><br /><br /><strong>Facts about the research</strong><br />The investigation was conducted jointly in Sweden by the Signals and Systems Department at Chalmers University of Technology, the Centre for Advanced Reconstruction of Extremities at Sahlgrenska University Hospital, and the Institute of Neuroscience and Physiology at the University of Gothenburg; all collaborating closely with the Biorobotics Institute of Scuola Superiore Sant’Anna in Italy.<br /><br />Read more about the Biomechatronics and Neurorehabilitation Laboratory (BNL) at Chalmers:<br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />BNL website</a><br /><a href="" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Chalmers BNL on Facebook</a><br /><br />Thu, 06 Apr 2017 07:00:00 +0200 vehicles a game changer for European manufacturing industry<p><b>​How will work environment, skills requirements and labour market be affected by the automotive industry&#39;s shift to manufacturing electric vehicles?

Electric vehicle technology is one of the “game changers” that are considered to have great impact on the labour market, when the automotive industry moves from the production of vehicles with conventional fuels to electric vehicle manufacturing.<br /><br />Representatives from West Swedish industry and academia, Region Västra Götaland and the Swedish Energy Agency recently met the study's project group, for a detailed discussion of how electric vehicles and vehicle production may affect where the jobs will be found and what skills will be in demand in ten years time. The meeting was preceded by literature studies and expert interviews, including an interview with the Swedish Electromobility Centre that hosted the meeting.<br /><br />Markus Lindström from Technopolis Group is one of those responsible for the study:<br /><br /><strong>What have you talked about today?</strong><br />– We have talked about the prospects for the electric vehicle industry, specifically in Västra Götaland and in Sweden in general. We have talked about new tasks, what knowledge will be in demand, potential changes in the work environment and the various parties’ roles during the transition phase.<br /><br />– The discussion confirmed that electric vehicle technology will affect the future of manufacturing mainly outside of the actual production, for example in systems development.<br /><br />Were any particular areas highlighted?<br />– We got a deeper discussion of battery manufacturing, and specific examples of how both industrial companies and Swedish Electromobility Centre works with education to meet the future need of knowledge and skills.<br /><br /><strong>Can you see any specific challenges for Sweden?</strong><br />– Yes, it is a challenge for Sweden that the country lacks some skills related to information and communication technology.<br /><br />According to the project's literature study, electric vehicle manufacturing is expected to affect the work environment considerably less than the other four game changing technologies. Generally speaking, we can look forward to tasks that involve more cooperation, flexibility and creativity, and fewer physical routine tasks. The study also estimates that in-service training will be needed in areas such as law and business management.<br /><br /><br /><strong>ABOUT THE STUDY</strong><br />The study &quot;The impact of game-changing technologies in the European manufacturing sector&quot; is carried out by Technopolis Group on behalf of Eurofound. The study is part of the program &quot;The future of manufacturing&quot;, launched by the European Parliament and the European Commission (DG GROW).

The name Electrical Engineering brings clarity to in which field we operate and where our strengths are. This is also in line with how our research area often is named in the academic world, not least internationally.<br /><br /><strong>What does this change mean?</strong><br />– About 50 colleagues will join us when forming the new research division Electric Power Engineering. All in all, E2 will consist of about 200 persons. In total this gives us very good conditions to become a strong team with prominent competence within the field of electrical engineering – no matter if it involves electricity, electrical signals, optical signals or microwaves etc. We bring together knowledge of software and hardware. This widens our scope, which will be of great value in many applications of research. <br /><br /><strong>Which advantages do you think that the new department will bring?</strong><br />– I see many advantages. We can deepen the cooperation that already exists and benefit even more from it, at the same time we open up for new ventures across boundaries. Jointly we can cope with the challenges in society of today, for example the growing demands concerning efficient systems for communications and electrifying. I am convinced that we by interacting via different skills can reach many fruitful forms of collaboration, not least among our doctoral students. In addition, we now are able to communicate more distinctly towards financiers and other external partners. The department of Electrical Engineering is going to play an important role in Chalmers´ comprehensive strategic aim concerning education, research and utilisation. <br />Fri, 10 Mar 2017 09:00:00 +0100 helmet yields fast and safe evaluation of head injuries<p><b>​Results from a clinical study demonstrates that microwave measurements can be used for a rapid detection of intracranial bleeding in traumatic brain injuries. A recently published scientific paper shows that health care professionals get vital information and can quickly decide on appropriate treatment if patients are examined using a microwave helmet.</b></p>​The study demonstrates a new health care application for microwave measurements. Previously, microwave measurements have been used to distinguish stroke caused by bleeding in the brain from stroke caused by cloth.<br /><br />The new study shows that the technology also applies to patients affected by traumatic brain injury, which is the most common cause of death and disability among young people. This type of injuries are often caused by traffic accidents, assaults or falls. An estimated 10 million people are affected annually by traumatic brain injuries.<br /><br />The study compared 20 patients hospitalized for surgery of chronic subdural hematoma – a serious form of intracranial bleeding – with 20 healthy volunteers. The patients were examined with microwave measurements which were compared to traditional CT scans. The results show that microwave measurements have great potential to detect intracranial bleeding in this group of patients.<br /><br />“The result is very promising even though the study is small and only focused on one type of head injury. The microwave helmet could improve the medical assessment of traumatic head injuries even before the patient arrives at the hospital”, says Johan Ljungqvist specialist in neurosurgery at the Sahlgrenska University Hospital. “The result indicates that the microwave measurements can be useful in ambulances and in other care settings.”<br /><span><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/MikaelPersson_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></span><br />Further studies of acute head injury patients are ongoing and planned in Sweden and abroad.<br /><br />“Microwave technology has the potential to revolutionize medical diagnostics by enabling faster, more flexible and more cost-effective care”, says Mikael Persson, professor of biomedical engineering at Chalmers University of Technology. “In many parts of the world microwave measurements systems can become a complement to CT scans and other imaging systems, which are often missing or have long waiting lists.”<br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/Mikael_Elam_200px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br />“It is challenging to develop a new clinical methodology, from early tests to a device for clinical use in a hyperacute clinical environment where routine care of patients cannot be delayed.

Elna Holmberg from Swedish Electromobility Centre was one of the invited experts at a round table talk about sustainable transport.</b></p>​How can people be encouraged to choose sustainable means of transport? This was one of the key questions when experts from state, region, industry and academia gathered for a round table discussion at Volvo Truck Experience Center with the Governor General of Canada David Johnston, in the presence of King Carl Gustaf and Prince Carl Philip.<br /><br />Elna Holmberg, Director of Swedish Electromobility Centre, was one of the invited experts, along with Mats Viberg, First Vice President of Chalmers University of Technology, Anna Johansson, Minister of Infrastructure and Martin Lundstedt, President and CEO of Volvo Group, among others.<br /><br /><strong>What did you talk about at the round table?</strong><br />“We talked about the importance of collaboration to implement the transition to sustainable transportation. We discussed congestion problems, new forms of ownership and different ways to get a higher utilization of vehicles. There is a lot going on right now, and we can learn from each other.”<br /><br /><strong>Did you bring up any particular issue?</strong><br />“I talked about the academy as a neutral party for producing knowledge. I emphasized the importance of informing society, both of the effects that increased greenhouse gas emission have - especially on health - and of the opportunities and the knowledge that grows and matures in the academic world.”<br /><br />“I also stressed the need to reduce the costs of electric vehicles. This can be done, for example, through collaborative research and demonstration projects. I believe in people’s ability to interact and create innovations that will solve the climate and congestion problems.”<br /><br />The meeting at Volvo Truck Experience Centre was part of the program when the Governor General of Canada David Johnston and his wife Dr Sharon Johnston payed a state visit to Sweden on 20-23 February 2017.<br /><br />Text: Emilia Lundgren<br />Photo:<br /><br /><a href=""><em>Swedish Electromobility Centre</em></a><em> is a national Centre of Excellence for hybrid and electric vehicle technology and charging infrastructure.

The next step, towards a terabit level, requires new technology. At Chalmers, a unique Massive MIMO testing environment is being built, a project in which Ericsson are pleased to be involved.</b></p>​In simple terms, future wireless communication requires two improvements: higher frequency spectrum and new antenna systems. Chalmers has the skills to achieve both – organised through two research centres, Chase and GigaHertz Centre, both funded by Vinnova. Through collaboration in the project MATE, they are jointly developing a test bed for Massive MIMO antenna technology.<br /><br />Björn Johannisson, research manager at Ericsson, is impressed with how the project has succeeded.<br />“It’s not always easy to create collaborative projects of this kind. The researchers need to get along, the partners have to find mutual interests, and the practical parts needs to be addressed. I’m impressed with how it has succeeded, and we see a great value in our collaboration with Chalmers,” he says.<br /><br /><img src="/en/centres/chaseon/PublishingImages/News/BjornJohannisson-quote_350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />MIMO, or “multiple input-multiple output”, is a technology that improves transfer capacity by adding a large number of antennas in both transmitters and receivers, making it possible to transmit multiple data streams simultaneously. Future systems may involve hundreds, or even thousands, of antennas.<br />“It means that you transmit several streams of information that mix in the air and must then be separated at the receiving end. We are currently developing technology to handle this effectively, but in the MATE project we also want to enable higher frequencies, which adds to our challenge. This requires collaboration because the signal processing must be adapted to the properties of the hardware.”<br /><br />Chalmers and MATE are at the forefront of the research, Johannisson claims.<br />“There are a number of test beds developed at companies, but this is one of the first being created for high frequencies in an academic environment. Which is important to us since the academic research is more transparent, and we want the technology to become globally acknowledged.”<br /><br />To Ericsson, the technology is interesting for the next generation of mobile systems, 5G. Massive MIMO will, however, have a significantly wider area of use than simply mobile phones – everything from connected cars and production environments in factories to small gadgets with communication features. Within the MATE project, a rough draft of how it will work has been drawn up, but many issues remain to be resolved regarding the precise design of the technology.<br /><br />“The test bed that is soon completed will be an important platform for further work. When Chase continues in ChaseOn, we will collect measurement data in order to test algorithms and to provide insights into how high-performance antenna systems can be designed,” concludes Johannisson.<br /><br />Text: Lars Nicklason<br />Photo: Henrik Sandsjö<br /><br /><br /><img src="/en/centres/chaseon/PublishingImages/News/MATE_350px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:150px;height:225px" /><br /><br />More about the MATE project:<br /><a href="/en/projects/Pages/Massive-MIMO-test-bed.aspx">Massive MIMO test bed, project start</a><br /><a href="/en/areas-of-advance/ict/news/Pages/test-bed-for-multi-antenna-systems.aspx">Short interview with Thomas Eriksson at the start of the MATE project</a> (Feb 2015)<br /><br />Fri, 10 Feb 2017 09:00:00 +0100 cells on the agenda for Swedish Electromobility Centre<p><b>​The interest in fuel cell technology is growing worldwide.

This will mainly be ensured by the antennas of tomorrow.</b></p>​ <br />If you are at home watching a film and the TV picture suddenly freezes, it’s probably not a disaster. But in the future, if you are driving towards a junction, in which a cloud-based automated driving application optimally guides you and other vehicles through the junction at full speed – well, in that situation communication must always work,” says Mikael Nilsson at Volvo Cars.<br /><br />Of course, it will be a while before this becomes a reality, but other new communication applications are already being developed that demand a very high level of reliability.<br /><br />Volvo’s Road Friction Information is one example. The idea is that cars ahead share information about road conditions to nearby vehicles through the cloud, for example about icy or slippery conditions, which is intended to make the surrounding cars to take precautions in time. In such circumstances, a stable link can mean the difference between life and death. The same applies to E-call, the service for automatic electronic emergency calls from cars to emergency call centres that will become standard in all new cars in Europe by 2018.<br /><br /><img class="chalmersPosition-FloatRight" src="/en/centres/chaseon/PublishingImages/News/ChaseOn-Volvo-citat2_270px.jpg" alt="" style="margin:5px" />What happens if a car flips over and the antenna on the roof breaks?<br />“Within Chase we have examined various concepts for how to best position antennas on cars,” says Nilsson.<br /><br />The aim has also been to develop the antennas of tomorrow.<br />“You can build better receivers, switch to better cables between the antenna and the receiver, but that is much more expensive than building better antennas. They will be the most crucial element that affects the performance of the communications system.”<br /><br />Within ChaseOn, Volvo aims at developing an antenna concept that supports new 5G technology. It requires higher frequencies, which in turn demands more of the antenna’s performance and position.<br /><br />“We also plan to develop antennas that are compatible with cars made of materials such as carbon fibre and plastic, which lack a ground plane.”<br /><br />For Volvo Cars, the Chase collaboration has also had what Mikael Nilsson describes as “softer values”.<br />“It is important for us to be part of research hubs, to be visible in these contexts, for instance at conferences around the world at which Chalmers’ researchers participate. It gives us a good reputation and spark enquiries about new projects and collaborations. This exchange between Volvo and universities is perhaps the most important of all.”<br /><br /><img src="/en/centres/chaseon/PublishingImages/News/Chaseon-Volvo-MikaelNilsson_750px.jpg" alt="" style="margin:5px" /><br /><em>Mikael Nilsson, Technical Expert Wireless Communication at Volvo Cars</em><br /><br /><br />Text: Lars Nicklason<br />Photo: Henrik Sandsjö<br /><br /><br /><img class="chalmersPosition-FloatRight" src="/en/centres/chaseon/PublishingImages/ChaseOn_Logo_220x120px.jpg" alt="" style="margin:5px" /><strong>Antenna systems research centre ChaseOn</strong><br />ChaseOn is a continuation of the very successful Chase centre.

Over 200 000 people worldwide have this type of hearing aids that uses the skull bone to transmit sound vibrations to the inner ear via so-called bone conduction.<br /><br />The Bone Conduction Implant (BCI) is a new type of hearing aid with several improved features developed by <span>researchers at Chalmers´ department of signals and systems, in collaboration with </span><span><span>Senior Physician <span style="display:inline-block"></span></span></span><span>Måns Eeg-Olofsson and his team at the ENT department, Sahlgrenska University Hospital.</span> The first patient received the BCI implant in December 2012 in Gothenburg, and it is today worn by 16 patients in a clinical study.<br /><br /><strong>Milestone celebrated </strong><br />Recently, a milestone was reached on the way to the goal of launching the BCI to the market in the future. The bone conduction implant has been kept “listening” to radio in an age-acceleration test chamber that accelerates the exposure time with a factor of approximately six times. <br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/Bo_Håkansson_320px.jpg" alt="" style="margin:5px" /><br />“The performance of the implant has been verified and monitored corresponding to ten years of normal usage time for patients who are using the hearing aid for eight hours on a daily basis”, says Professor Bo Håkansson, originator of the bone conduction hearing aids and a pioneer in the field with 40 years´ research experience.<br /><br />The long term endurance test shows that the life span of the implant is longer than the desired minimum time for implants in the human body, often considered to be ten years.<br /><br /><br /><br /><br />“Once a month, for twenty months, we have monitored the implant performance at different frequencies”, says PhD-student Karl-Johan Fredén Jansson, who is responsible for these validations, which also is an important part of his coming doctoral thesis. “We are pleased to note that we during this time haven’t seen any impairment in the implant function.”<br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/Karl-Johan-Freden-Jansson_320px.jpg" alt="" style="margin:5px" /><br /><strong><br />Simulating conditions in the human body</strong><br />The test chamber was constructed about two years ago by the student Helga Jóna Harðardóttir, who started the project during her master thesis project at Chalmers.<br /><br />To simulate the real conditions in the human body, the temperature in the test chamber is kept at 37 degrees Celsius. The Swedish national radio P1 has proved to be the best radio channel to use in the test, since the broadcasts resemble a good mix of the sounds you are exposed to during an ordinary day at work, comprising both spoken words and other sounds.<br /><br />The researchers can whenever they want connect and listen how the sound would be perceived inside of the head of the patient using the implant, through a so called skull simulator.<br /><br /><strong>Valuable meetings with patients </strong><br />Evaluations are also done concerning how the patients in the study experience the life with their new hearing aid and they regularly come to Chalmers to do follow-up visits and hearing tests.<br /><br />”So far we have received good responses from the participants and haven’t had any serious complications”, says Professor Bo Håkansson. “To meet grateful patients, who feels a higher quality of life, gives us a very strong motivation to carry on with our work.”<br /><br /><strong>Heading for long term goal</strong><br />In the meantime the implant continues to “listen” to radio in the test chamber. The aim is to collect more data, which gives information about how the implant reacts if the hearing aid is used for more years and over eight hours on a daily basis.<br /><br />The long term goal is to get CE-mark in the EU and approval from the US Food and Drug Administration, FDA. Important information to qualify for these requirements, concerns for example safety issues towards the patient, technical function and hearing rehabilitation. These are essential steps on the way of launching the BCI as a new hearing aid for general use in healthcare, and to offer improved hearing rehabilitation for more people.<br /><br />Text: Yvonne Jonsson<br />Photo: Oscar Mattsson<br /><br /><br /><strong>This is how the Bone Conduction Implant (BCI) works</strong><br /><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/BCI-implantat+processor_i_hand_320px.jpg" alt="" style="margin:5px" />The implant is slightly less than six centimeters long. By a surgical procedure, it is implanted in the skull bone under the skin at a position behind the ear. Sound is transmitted wirelessly from an externally worn sound processor to the implant by an induction link, comprising one transmitter coil in the sound processor and one receiver coil in the implant. The patient can easily attach or remove the sound processor from the head as it is magnetically attached over the implant. <br /><br />The audio signal is transmitted to a tiny quadratic loudspeaker anchored to the bone near the auditory canal. The speaker generates sound vibrations which reaches the sensory organs of the cochlea, and is further by the brain interpreted as sound.<br /><br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Ny%20unik%20benförankrad%20hörapparat%20klarade%20långtidstest/BCI_320px.jpg" alt="" style="margin:5px" />In comparison with the convention Bone Anchored Hearing Aid (BAHA), the wireless link keeps the skin intact because there is no titanium screw needed through the skin.  <br /><br />Thanks to a new type of transducer technique, the BCI transducer can be made small, but as powerful as a BAHA, and at the same time avoid complications related to a titanium screw through the skin.<br /><br />Illustration: Boid/Chalmers<br /><br /><br /><br /><br /><br /><a href="/en/departments/e2/research/Signal-processing-and-Biomedical-engineering/Pages/Biomedical-signals-and-systems.aspx">&gt; Read more about research in biomedical signals and system</a><br /><br />Fri, 27 Jan 2017 00:00:00 +0100 call for WASP Industrial PhD students<p><b>Wallenberg Autonomous Systems and Software Program (WASP) is now offering up to 17 industrial doctoral student positions at the five partner universities.
