News: Informations- och kommunikationsteknik related to Chalmers University of TechnologyTue, 12 Sep 2017 17:49:01 +0200 project that sets the standard for 5G in vehicles<p><b>​The development of 5th generation mobile broadband systems, 5G to replace today&#39;s 4G, is in full swing. Chalmers is part of a two-year project that brings together industry and academia to develop a common global standard for future vehicle communication.</b></p>​“It's about using telecommunications to increase traffic safety and transport efficiency through connected and collaborative systems”, says Professor Erik Ström, Head of Communication and Antenna Systems at the Department of Electrical Engineering. “Today's wireless mobile system is not powerful enough to be used for vehicle communication, where safety always must be put first.”<br /><br />For traffic safety applications, very high demands are imposed on the reliability of the data being transmitted. In some cases, more than 99.999 percent of the transmitted information must also be delivered to the recipient.<br /><br />“In addition to the demands of high reliability, it is also crucial that data communication is fast and not delayed”, he continues. “In order to be traffic-safe, transmission times have to be as short as 5 milliseconds in certain use cases. This is very challenging.”<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Projektet%20som%20sätter%20standarden%20för%205G%20i%20fordon/Erik_Strom_200x280px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><strong>Creates consensus among competitors</strong><br />In the project, competitors like Ericsson, Nokia and Huawei side by side, along with vehicle manufacturers like Volvo Cars and PSA, work out the common prerequisites for the 5G system and a global standard for vehicle communication.<br /><br />The work is about creating consensus and to agree on matters that need to be standardized. The telecom industry requires a common system platform to start from, when the manufacturers in the next step separately develop their products for the market.<br /><br />&quot;I am very pleased that we at Chalmers are taking part in setting the standard”, says Erik Ström. “It is an important and highly sought-after network to participate in, including both industry and other universities. We contribute, among other things, with knowledge from our fundamental research on positioning and wireless systems. In total, we expect the project to involve 46 month´s work for our researchers.”<br /><br />A part of the project is about vulnerable road users, such as pedestrians and cyclists. When the 5G technology is available in each person's mobile phone, data collection for example about position, direction and speed could be used to further enhance traffic safety in different situations.<br /><br />The project started in June 2017, and Chalmers made the first part-delivery in early September. By mid-2019, selected technology components will be demonstrated and project results incorporated into the 5G standard. The overall goal of 5GCAR is that vehicles connected with 5G technology will be out on the roads from 2020.<br /><br /><strong>Renewed confidence</strong><br />&quot;We are very pleased to, once more, been given the confidence to use our research in the development of technology that enables 5G in vehicles&quot;, says Erik Ström. “For us, this is the second project within 5GPPP. We have long and fruitful partnerships in the past with Ericsson and Volvo Cars and other 5GCAR partners.”<br /><br /><br /><strong>Facts about 5GCAR</strong><br /><ul><li>5GCAR stands for &quot;Fifth Generation Communication Automotive Research and Innovation&quot;.</li> <li>The project is funded by the EU and has a budget of EUR 8 million.

She is being interviewed in the new issue, in which her latest scientific paper – co-written with colleagues at Chalmers and Hewlett Packard Enterprise in the U.S – is published as well.<br /><br /><img src="/SiteCollectionImages/Institutioner/MC2/News/vcsel_array_350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Ewa Simpanen's research is about increasing the wavelength for low-cost laser and fiber technology to meet the growing needs of optical interconnects in the massive data centres – operated by giant service providers like Facebook and Google – that underpin our Internet-enabled world. <br />“The purpose of this work is to develop high-speed, longer wavelength those while still using the GaAs-based material systems as it enables the fabrication of VCSELs which are superior to those based on other material systems in terms of speed, efficiency, manufacturability, and cost”, says Ewa Simpanen.<br /><br />In the June issue of Electronics Letters she and her colleagues present a VCSEL design operating at 1060 nanometer, equal to one millionth of a metre.<br />“We have limited the wavelength extension to 1060 nm since the long-term reliability of GaAs-based VCSELs may be compromised if extending the wavelength beyond ∼1100 nm”. It is a longer wavelength than the current GaAs standards, located at 850 and 980 nm, to reduce chromatic dispersion and attenuation in the fiber, which is crucial for reaching the longer ranges of data centers. We have tried to find a sweet spot with the wavelength in between, explains Ewa Simpanen for Electronics Letters.<br /><br />VCSEL means vertical-cavity surface-emitting laser.<br /><br />Text and photo: Michael Nystås<br /><br />Caption: <br />A microscope image of an array of VCSEL devices on chip; newly fabricated and ready for characterisation.<br /><br /><a href="">Read the article in Electronics Letters</a> &gt;&gt;&gt;<br /><br />Source: Electronics Letters, Volume 53, Issue 13, 22 June 2017, page 819<br />DOI:  10.1049/el.2017.2117 , Print ISSN 0013-5194, Online ISSN 1350-911X<br />Tue, 08 Aug 2017 09:00:00 +0200, sustainable data processing with hyper effective memory compression<p><b>​A new technology for memory compression developed at Chalmers has proved capable of saving up to two thirds of memory and bandwidth with retained performance. The technology is now finding its way to the market through ZeroPoint Technologies AB,  a startup company founded by professor Per Stenström and his former PhD student Angelos Arelakis.</b></p><img src="/SiteCollectionImages/Institutioner/DoIT/News/Angelos.jpg" class="chalmersPosition-FloatRight" alt="Angelos Arelakis" style="margin:5px" />When Angelos Arelakis began his doctoral studies with Per Stenström at Chalmers in 2010, they sat down to discuss possible topics for the dissertation, and the potential of memory compression came up. Per Stenström suggested &quot;a simple experiment to get things on the road&quot;, and the results of those tests were far beyond all expectations. The research that has followed has now evolved into a promising business concept. <br /><br />Usually the subject of memory compression is about compressing data to be stored or transported without processing. In modern computers arithmetic operations are performed in the CPU, which means that data must be fetched from memory when calculations are to be made, traffic that costs both time and energy. The new technology developed at Chalmers handles active data, while it's being processed. <br /><br />&quot;The benefit of the technology is increased memory capacity, but also increased CPU and memory throughput, which basically will lead to improved performance without affecting the physical size of the memory, or the energy consumption,&quot; says Angelos Arelakis. <br /><br />He left Chalmers earlier this year to become chief system architect at ZeroPoint Technologies AB, the company he founded with Per Stenström in 2015, with the goal of commercializing the technology he developed as a PhD student. The company aims to release its first product on the market in 2017, and as the technology can be applied to all types of data, the potential customers are companies that deal with everything from smartphones to major computer centers. Already in the early research results, Per Stenström anticipated future commercial opportunities, and the first patent application was filed in 2012. Since then, six more applications have been submitted, and the first patent has been granted. <br /><br />Solutions that improve storage capacity through different compression systems and methods are already on the market, some are even fast enough to also provide improved memory capacity. What's unique with the technology from Zeropoint is the combination of speed, intelligent compression and generality. Because the compression algorithms are implemented in hardware logic rather than in the software, they become extremely fast, and the software developers can continue as usual without the need for any adjustments. The company has evaluated various applications in collaboration with several international IT companies. <br /><br />&quot;There is no golden business model, you need to do trial and error. We have taken different applications to some potential customers, and they need to verify that the technology works. If it doesn't make sense, it's not meaningful to proceed. The product we are closest to launching now is a licensed IP core,&quot; says Angelos Arelakis. <br /><br />ZeroPoint Technologies AB has received start-up contributions from, among others, Chalmers Ventures and Qamcom, to take the product to the market. Angelos Arelakis has also been awarded a scholarship from <em>King Carl XVI Gustaf's 50th birthday foundation for science, technology and the environment</em> to further develop his research. The company currently employs about 8 people, but recruits continuously for new positions.

The discovery is published in the scientific journal Nature Communications.</b></p><div><img src="/SiteCollectionImages/Institutioner/MC2/News/saroj_nature_prm_pic_1_665px.jpg" alt="" style="margin:5px" /><br />Spin as the information carrier can result in electronics that are significantly faster and more energy efficient. It can also lead to more versatile components capable of both data calculation and storage. </div> <div> </div> <div>Just over two years ago, the same research group at Chalmers University of Technology demonstrated that graphene, which is an excellent electrical conductor, also has unsurpassed spintronic properties.</div> <div> </div> <div>The super-thin carbon mesh proved capable of conveying electrons with coordinated spin over longer distances and preserving the spin for a longer time than any other known material at room temperature.</div> Although the distance is still on the scale of a few micrometres and the time is still measured in nanoseconds, this in principle opened the door to the possibility of using spin in microelectronic components. <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/saroj_prasad_dash_350x305.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" />“But, it is not enough to have a good motorway for the spin signal to travel on. You also need traffic lights so the signal can be controlled,” says Associate Professor Saroj Dash, leader of the research group.</div> <div>“Our new challenge became finding a material that can both convey and control the spin. It is hard, since both tasks normally require completely opposite material properties,” he explains.</div> <div> </div> <div>Like many other researchers in the hot field of graphene, the Chalmers researchers therefore chose to test a combination of graphene and another thin, so-called two-dimensional material, with contrasting spintronic properties. <br /></div> &quot;Our material of choice was molybdenum disulphide, MoS2, due to its low spin lifetime steaming from high spin-orbit coupling,&quot; states André Dankert, postdoc researcher in the group. <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/andre_dankert_2017_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />André Dankert (to the right) and Saroj Dash designed an experiment where a few layers of molybdenum disulphide were placed on top of a layer of graphene in a type of sandwich, referred to as a heterostructure. With this, they could identify in detail what happens to the spin signal when the electron current reaches the heterostructure:</div> <div> </div> <div>“Firstly, the magnitude of the spin signal and lifetime in graphene is reduced tenfold just through the close contact with molybdenum disulphide. But, we also show how one can control the signal and lifetime by applying electrical gate voltage across the heterostructure,” explains Saroj Dash.</div> <div>This is because the natural energy barrier that exists between the material layers, called the Schottky barrier, reduces when the electrical voltage is applied. With this, the electrons can quantum mechanically tunnel from the graphene into the molybdenum disulphide. This causes spin polarisation to disappear; the spin becomes randomly distributed.</div> <div> </div> <div>Opening or closing a “valve” in this manner by regulating a voltage is similar to how a transistor works in conventional electronics. Nonetheless, Saroj Dash is a little hesitant to call the device a spin transistor.</div> <div>“When researchers proposed on future spin transistors, they often imagined something based on semiconductor technology and so called coherent manipulation of electron spin. What we have done works in a completely different way, but performs a similar switching task,” he says.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/saroj_nature_prm_pic_2_665px.jpg" alt="" style="margin:5px" /><br />“This is the first time that anyone has been able to demonstrate that the gate control of spin current and spin lifetime works at room temperature – which naturally increases the possibilities for different applications in the future,” says Saroj Dash. </div> <div> </div> <div>Although it is too early to predict what these would be, Dash points out that a component based on this principle might be extremely versatile because it contains magnetic memory elements, semiconductors and graphene, as well as having the capability of performing spintronic switching.</div> <div>“It points to a multifunctional component that can handle both data storage and processor work – in a single unit.”<br /><br />Text: Björn Forsman<br />Photo of Saroj Prasad Dash: Oscar Mattsson<br />Photo of André Dankert: Michael Nystås<br /></div> <div> </div> <h4 class="chalmersElement-H4">Facts: Molybdenum disulphide, MoS2</h4> <div>Molybdenum disulphide is a semiconducting substance that many have come in contact with, since it is the active ingredient in a certain type of lubricant sold at your local filling station.</div> <div>With its layered structure, molybdenum disulphide has similarities to graphite, which is made up of several layers of graphene that stick together. However, when it comes to spintronics the materials are each others' opposites. Molybdenum disulphide does not allow any polarised electron current to pass through whatsoever. The spin signal meets a sudden death since the electrons quickly return to their natural, random blend of up-spin and down-spin.</div> <div> </div> <h4 class="chalmersElement-H4">Facts: Spin and spintronics</h4> <div>Spin is a quantum mechanical property of electrons and other elementary particles. The spin is either directed up or directed down.

A first example that we will consider is a simple robot that is controlled by the human but it can autonomously avoid obstacles.<br /><br /><strong>How is it possible to control a robot by using the power of thought?</strong><br />The “power of thought” results in myoelectric signals that reflect the human intention of motion. By measuring, processing, and decoding these signals, the human intention could be send as a control command to the robot.<br /><br /><strong>In which applications could this be used?</strong><br />There is a variety of relevant applications related to partial automation such as assistive devices like exoskeleton (an external, artificial skeleton that protects and helps the person to move) or powered wheelchairs where the control is shared between a motor impaired human user and the device.  <br /><br /><strong>What are the main challenges you are confronted to?</strong><br />The most important challenge is to make a system that the human user can accept both in terms of performance and ease of use. <br /><br /><strong>This project is a part of an initiative to encourage interdisciplinary research.

So far, the terahertz (THz) frequency has not been optimally applied to data transmission, but by using graphene, researchers at Chalmers University of Technology have come one step closer to a possible paradigm shift for the electronic industry.</b></p><div>Over 60 young researchers from all over the world will learn more about this and other topics as they gather in outside of Gothenburg, Sweden, to participate in this week's summer school Graphene Study, arranged by Graphene Flagship.</div> <div> </div> <div>It is the EU's largest ever research initiative, the Graphene Flagship, coordinated by Chalmers, who organises the school this week, 25-30 June 2017. This year it is held in Sweden with focus on electronic applications of the two-dimensional material with the extraordinary electrical, optical, mechanical and thermal properties that make it a more efficient choice than silicon in electronic applications. Andrei Vorobiev is a researcher at the Terahertz and Millimetre Wave Laboratory at the Department of Microtechnology and Nanoscience - MC2 - as well as one of the many leading experts giving lectures at Graphene Study. He explains why graphene is suitable for developing devices operating in the THz range:</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/andrei_vorobiev_MC2_S8A0112-2_220x180.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“One of the graphene’s special features is that the electrons move much faster than in most semiconductors used today. Thanks to this we can access the high frequencies (100-1000 times higher than gigahertz) that constitutes the terahertz range. Data communication then has the potential of becoming up to ten times faster and can transmit much larger amounts of data than is currently possible”, says Andrei Vorobiev (to the right).</div> <div> </div> <div>Researchers at Chalmers are the first to have shown that graphene based transistor devices could receive and convert terahertz waves, a wavelength located between microwaves and infrared light, and the results were published in the journal IEEE Transactions on Microwave Theory and Techniques. One example of these devices is a 200-GHz subharmonic resistive mixer based on a CVD graphene transistor integrated on silicon that could be used in high-speed wireless communication links.</div> <div> </div> <div>Another example, taking advantage of graphene’s unique combination of flexibility and high carrier velocity, is a power detector based on a graphene transistor integrated on flexible polymer substrates. Interesting applications for such a power detector include wearable THz sensors for healthcare and flexible THz detector arrays for high resolution interferometric imaging to be used in biomedical and security imaging, remote process control, material inspection and profiling and packaging inspection.</div> <div> </div> <div>“Analysis show that flexible imaging detector arrays is an area where THz applications of graphene has a very high impact potential. One example of where this could be used is in the security scanning at airports. Because the graphene-based terahertz scanner is bendable you’ll get a much better resolution and can retrieve more information than if the scanner's surface is flat,” says Vorobiev.</div> <div> </div> <div>But despite the progress, much work remains before the final electronic products reach the market. Andrei Vorobiev and his colleagues are now working to replace the silicon base on which the graphene is mounted, which limits the performance of the graphene, with other two-dimensional materials which, on the contrary, can further enhance the effect. And Vorobiev hopes that he will be able to inspire the students participating in Graphene Study to reach new scientific breakthroughs.</div> <div> </div> <div>“In the last fifty years, all electronic development has followed Moore's law, which says that every year more and more functions will being applied on ever smaller surfaces. Now it seems that we have reached the physical limit of how small the electronic circuits can become and we need to find another principle for development. New materials can be one solution and research on graphene is showing positive results. Working with graphene-related research is about breaking new ground which involves many difficult challenges, but eventually our work can revolutionise the future of communication and that's what makes it so exciting,&quot; says Andrei Vorobiev.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/graphene-mixer-2_750px.jpg" width="676" height="507" alt="" style="margin:5px" /><br /><em>The sandglass shaped 40 μm wide graphene field-effect transistor, seen in the middle of the image, could be a key component in future high-speed wireless communication links. </em><span style="font-family:&quot;helvetica neue&quot;,helvetica,arial,sans-serif;font-size:13px;letter-spacing:normal;text-align:left;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;display:inline !important;float:none"><em>Illustration: Michael A.

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.

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 much appreciated Initiative seminar on Digitalisation<p><b>​We summarize our two-day seminar and describe how the Area of Advance ICT are planning for continued work forward.</b></p>​ <br />With 330 participants over two days and a total of 34 speakers, we can proudly summarize the initiative seminar on Digitalisation as a success. The evaluation showed that the participants were satisfied or very satisfied and they particularly emphasized the wide range of prominent speakers who gave different perspectives on the current theme – opportunities and challenges of digitalisation.<br /><br />Our participants also represented a wide range. About 30 percent came from industry or private sector, slightly less than ten percent from the public sector and half of the participants were from Universities or research institutes. The remaining ten percent were students from Chalmers and University of Gothenburg.<br /><br />Chalmers DigiLab, a workshop for school children, which was arranged parallel to the seminar at Chalmers conference center, received 120 children over the two days. Twelve Chalmers students tutored the children under project management from Steve Cook, Norconsult.<br /><br /><strong>What do we take with us from our two days?</strong> A common message from the presentations was that the digitalisation process is here in its full speed. Many technologies exist today and many new are appearing, many of them developed at Chalmers. The question is how to apply and combine these technologies to obtain the best results?  The consequences of digitalisation will be enormous. The society has to deal with it.<br /><br />The seminar was a starting activity of a new initiative Digitalisation@Chalmers. The Area of Advance ICT has initiated an analysis on concrete digitalisation activities, and needs from industry and public sector, mapping them to Chalmers activities in research. The analysis will show the potential for Chalmers advances in the digitalisation process, for the future research, and research education. This will lead to new activities supported by ICT: preparation for new interdisciplinary projects and involvement in new national and international activities.<br /><br /><img src="/en/areas-of-advance/ict/events/digitalisation/PublishingImages/IvicaCrnkovic_250px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><br /><br />Ivica Crnkovic<br />Director of Chalmers Area of Advance Information and Communication Technology<br /><br /><br /><a href="" target="_blank">Read the summary from one of our prominent speakers, Ulrich Sendler &gt;&gt;</a><br /><br /><br />Links:<br /><a href="">All the presentations were filmed and are available here &gt;&gt;</a><br /><span><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/education/chalmers_digilab_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></a><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"></a></span><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/programme.aspx">The presentation slides &gt;&gt;</a><br /><br /><a href="">Photos from the days &gt;&gt;</a><br /><br /><a href="/en/areas-of-advance/ict/events/digitalisation/Pages/for-schools.aspx"><br />Video from Chalmers DigiLab &gt;&gt;</a><br /><br /><a href="">Photos from Chalmers DigiLab &gt;&gt;</a><br /><br /><br />Fri, 07 Apr 2017 08:00:00 +0200 and touch mediate sensations via osseointegrated prostheses<p><b>​ A new study has found that people with a prosthesis attached directly to their skeleton can hear by means of vibrations in their implant. 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 Area of Advance Workshop on Smart Cities initiated by Building Futures<p><b>​On March 8th 2017 AoA directors and profile leads from Building Futures, Energy, Transport and ICT came together to discuss the concept &quot;Smart City&quot; and identify challenges which can be tackled by joint research initiatives at Chalmers.</b></p>​Smart City has been one of the buzzwords that gained a lot of attention in recent years, yet there is little consensus about what a Smart City actually is or should be.

The main question here is how functionality and resilience in growing cities can be assured? To many the answer seems to be “by making them smarter”. But how exactly do we make it happen? What technologies are needed and which city dimensions are affected? And finally, how can Chalmers’ Areas of Advance contribute to addressing this important challenge? <br /><br />The purpose of the mapping process initiated by Building Futures in November was to find answers to the above questions and to identify a structured way to utilize the concept of Smart Cities at Chalmers. AoA Building Futures director Henriette Söderberg explains that “often researchers are not aware of the fact that their projects directly contribute to the wide domain of Smart Cities. Our goal is to make the Smart City debate tangible for our researchers.”<br /><br />After laying the groundwork through literature review, several interviews with stakeholders from research, industry and the public sector were conducted. With respect to the <a href="/en/areas-of-advance/Pages/default.aspx">challenge-driven character of the Areas of Advance</a> 144 different Smart City challenges in 9 dimensions were collected and visualized on a large map. <br /><br />The Smart City challenge map was the point of departure for the AoAs workshop held on the 8th of March 2017. As a result of the workshop, five possible fields of action for the Areas of Advance were identified:<br /><br /><ul><li>Cyber security</li> <li>Circular economy</li> <li>Multimodal transport</li> <li>Virtual cities</li> <li>New urban planning</li></ul> <br />In the weeks to come, further strategic discussions within the Areas of Advance will take place and concrete next steps on how to anchor the Smart City topic at Chalmers will be taken. <br /><br /><img src="/en/areas-of-advance/buildingfutures/news/Documents/Workshop%208%20mars%202.jpg" alt="Workshop 8 mars 2.jpg" style="margin:5px" /><br /><br /><br />Fri, 31 Mar 2017 17:00:00 +0200
