Scientists at Chalmers and Xi&#39;an Jiaotong University, China now present a new way of taking this promising concept closer to large-scale application. An interlayer, made of a spreadable, ‘butter-like’ material helps improve the current density tenfold, while also increasing performance and safety.​​​​​​​​</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/350x305/Shizhao_Xiong_350x305.jpg" class="chalmersPosition-FloatRight" alt="Porträtt av forskaren Shizhao Xiong " style="margin:5px;width:170px;height:150px" /><div>“This interlayer makes the battery cell significantly more stable, and therefore able to withstand much higher current density. What is also important is that it is very easy to apply the soft mass onto the lithium metal anode in the battery – like spreading butter on a sandwich,” says researcher Shizhao Xiong at the Department of Physics at Chalmers.</div> <div><br /></div> <div>Alongside Chalmers Professor Aleksandar Matic and Professor Song's research group in Xi'an, Shizhao Xiong has been working for a long time on crafting a suitable interlayer to stabilise the interface for solid state battery. The new results were recently presented in the prestigious scientific journal Advanced Functional Materials.</div> <div><br /></div></span><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/solidstatebatterilabb750x.jpg" class="chalmersPosition-FloatLeft" alt="Bild från batterilabbet på Fysik på Chalmers." style="margin-top:5px;margin-bottom:5px;margin-left:10px;height:263px;width:350px" /><span style="background-color:initial"><div>Solid state batteries could revolutionise electric transport. Unlike today's lithium-ion batteries, solid-state batteries have a solid electrolyte and therefore contain no environmentally harmful or flammable liquids.</div> <div>Simply put, a solid-state battery can be likened to a dry sandwich. A layer of the metal lithium acts as a slice of bread, and a ceramic substance is laid on top like a filling. This hard substance is the solid electrolyte of the battery, which transports lithium ions between the electrodes of the battery. But the ‘sandwich’ is so dry, it is difficult to keep it together – and there are also problems caused by the compatibility between the ‘bread’ and the ‘topping’. Many researchers around the world are working to develop suitable resolutions to address this problem.</div> <div><br /></div> <div>The material which the researchers in Gothenburg and Xi'an are now working with is a soft, spreadable, ‘butter-like’ substance, made of nanoparticles of the ceramic electrolyte, LAGP, mixed with an ionic liquid. The liquid encapsulates the LAGP particles and makes the interlayer soft and protective. The material, which has a similar texture to butter from the fridge, fills several functions and can be spread easily.</div> <div>Although the potential of solid-state batteries is very well known, there is as yet no established way of making them sufficiently stable, especially at high current densities, when a lot of energy is extracted from a battery cell very quickly, that is at fast charge or discharge.

Researchers from Chalmers University of Technology and the University of Gothenburg studied the construction of an eight km stretch of road in detail and calculated how much emissions can be reduced now and until 2045, looking at everything from materials choice, production technology, supply chains and transport.</b></p><div><span style="background-color:initial">“We identified several low hanging fruits, and if we address those first, it will become easier and cheaper to make bigger emission reductions in the future,” says Ida Karlsson, PhD student at Chalmers, and participant in the Mistra Carbon Exit project.</span></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>The researchers evaluated opportunities for reducing emissions in an eight kilometre stretch of the Swedish highway 44 between Lidköping and Källby, which was finished in 2019. It was one of the Swedish Transport Agency’s first projects in which a complete climate calculation was made. All the materials and activities involved in its construction were calculated for their total climate impact – energy and materials used in the construction and what emissions these contribute to.<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“We used the contractor Skanska's climate calculation as an input for breaking down emissions by materials and activities and then analysed how much they could be reduced.

What alternatives are available, and how might those alternatives develop until 2045?” explains Ida Karlsson.  </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>The climate calculation showed that the contractor would be able to reduce emissions by 20 percent compared to the Swedish Transport Agency's reference values.

These require both time and large investments and include, for example, production of steel, cement, concrete and asphalt without carbon dioxide emissions, as well as fossil-free or electric vehicles. Solutions are being developed and implemented, but climate-saving technologies and choices exist already today. Ida Karlsson wants to highlight four of these:</div> <div> </div> <div> </div> <div> </div> <div>• Transport optimisation</div> <div> </div> <div> </div> <div> </div> <div>• Recycling and reuse of excavation masses, asphalt and steel</div> <div> </div> <div> </div> <div> </div> <div>• Material efficiency and design optimisation</div> <div> </div> <div> </div> <div> </div> <div>• Replacement of cement clinker as a binder in concrete</div> <div><br /></div> <div> </div> <div> </div> <div> </div> <div>“If you were to optimise the transportation of materials, excavation masses and waste, for example, large gains could be made. We could be better at transport logistics in Sweden. In addition to transporting materials and waste to and from a road construction site, many movements also take place within projects,” she explains. </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>The study ‘Reaching net-zero carbon emissions in construction supply chains - Analysis of a Swedish road construction project’ was published earlier this year in the journal Renewable and Sustainable Energy Reviews, and was written by Ida Karlsson together with colleague Filip Johnsson of Chalmers and Johan Rootzén, at the Gothenburg School of Business, Economics and Law.</div> <div> </div> <h2 class="chalmersElement-H2"> </h2> <div> </div> <h2 class="chalmersElement-H2">Biomass an important issue</h2> <div> </div> <div> </div> <div> </div> <div>Biomass plays an important role in both the short and long term. Many industries need biomass to reduce their emissions. It can be used for example as a fuel in the production of asphalt, cement and steel, for electricity production or as a vehicle fuel. Already today Sweden imports 95 per cent of the raw materials needed for transport biofuel because it is cheaper than using domestic material. It is hardly a sustainable solution when more and more countries import biomass. Ida believes that we need a coherent national strategy for biomass production and use.<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“Where there are fossil-free alternatives, such as electrification, these should be used. But then the politics must clearly steer towards such a development. Otherwise, the biomass will simply go to the one who pays the most and not to where it would have the best use.”</div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Further areas for improvement</h2> <div> </div> <div> </div> <div> </div> <div>Another area for improvement could be the recycling of asphalt, explains Ida Karlsson.<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“The legislation for this has recently changed but new, more efficient ways of working are not yet fully implemented. There are also different technologies to choose from depending on the quality of the tarmac, how heavy the vehicles which travel the route are and so on. Recycling requires energy but can still reduce emissions considerably, since asphalt is largely made up of bitumen, a variant of crude oil.” <br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>Concrete is another major source of emissions. In Sweden, cement clinker is used as a binder in infrastructural concrete, but in other countries, materials such as slag from steel production or fly ash from coal-fired power plants is used as partial replacement of cement clinker, reducing emissions considerably.</div> <div> </div> <div> </div> <div> </div> <div>“Here we must dare to recognise the long positive experiences from its use in other countries, like Norway, and adopt these techniques and measures even if they have not been used before in Sweden.”</div> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2"> </h2> <h2 class="chalmersElement-H2">Time to take a clear path forward</h2> <div> </div> <div> </div> <div> </div> <div>Ida Karlsson calls for clear plans, first until 2030, then onwards to 2045 as well.</div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“If you already know what you want in 2030, you can make demands today. And then companies can also know that ‘OK, if we have to be able to meet these requirements by 2030, then we have the opportunity to invest in technology to achieve that’. Because large investments will be needed to change production and haulage operations. Then you have to make sure that there are requirements, needs, incentives and not least that there is climate neutral electricity available.”<br /></div> <div> </div> <div> </div> <div> </div> <div> </div> <div>“The transformative solutions - electrification, carbon capture, carbon-free steel and concrete - require time and significant investment. But if we have already picked the low hanging fruits, the cost increase for the transformative solutions need not be so great. That is why the low-hanging fruits are so important to get started with, because they make it easier cut emissions further in the future, at a lower cost.”</div> <div> </div> <div> </div> <div> </div> <div> </div> <div><div><strong>For more information, contact:</strong></div> <div>Ida Karlsson</div> <div>PhD student, Department of Space, Earth and Environment, Chalmers University of Technology</div> <div><a title="mail" href="mailto:ida.karlsson@chalmers.se"><span>ida.karlsson@chalmers.se​​</span>​</a><br /></div> <div>+46317726517</div></div> <div> </div> <div> </div> <div> </div> <div><br /> </div> <div><strong>Text: </strong>Christian Löwhagen </div>Mon, 18 May 2020 00:00:00 +0200https://www.chalmers.se/en/news/Pages/Autumn-semester-will-start-both-on-campus-and-remotely.aspxhttps://www.chalmers.se/en/news/Pages/Autumn-semester-will-start-both-on-campus-and-remotely.aspxAutumn semester will start both on campus and remotely<p><b>In order to reduce the risk of spreading the coronavirus further, teaching in the autumn will be carried out with a mixture of remote and campus-based education.

The theory predicts when a phase crystal can arise, explaining previous numerical results, and is presented in an article recently published in the scientific journal Physical Review Research.</b></p><div>Quantum mechanical states are described by a complex-valued wave function, which similar to a wave has both an amplitude and a phase. In contrast to a classical wave, the amplitude and phase of the wave function are related to purely quantum mechanical phenomena which lack an analogue in classical physics.</div> <div> </div> <div>“A perfect example is superconductivity, which is a quantum-mechanical state that arises in certain materials due to electron pairing. The pairs have a quantum-mechanical wave function with an amplitude corresponding to the pair density, and a phase which is related to the pair momentum. The pairs move like an inviscid fluid through the material, with zero electrical resistance”, explains Patric Holmvall (below to the left), researcher at the Applied Quantum Physics Laboratory at MC2, and the lead author of the article.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/pholmvall_350x305.jpg" alt="Picture of Patric Holmvall." class="chalmersPosition-FloatLeft" style="margin:5px" />The researchers’ study shows that in certain superconductors with pathological edges that destroy superconductivity, the kinetic energy can change sign and become favorable as it “heals” the destroyed superconductivity. </div> <div>“We find that the phase crystallizes and form a periodic pattern, which in turn creates a checker-board pattern of circulating currents and spontaneous magnetic fields”, says Patric Holmvall.</div> <div> </div> <div>Currents and magnetic fields usually only enter superconductors under external influence and perturbations, but now arise spontaneously. This is an example of spontaneous pattern-formation, where inhomogeneities which usually cost energy instead heal a destroyed system. </div> <div>“We have derived the conditions for phase crystallization and use a microscopic theory to show that these conditions are satisfied in for example the material YBCO. Our theory combines and explains a number of theoretical studies reaching all the way back to the 1990s, in particular our previous numerical results, which were recently published in Nature Physics and Nature Communications”, says Patric Holmvall.</div> <div> </div> <div>The researchers' studies show that phase crystals represent a unique class of inhomogeneous ground states. </div> <div>“To derive the conditions for phase crystallization, we had to generalize the commonly used Ginzburg-Landau theory, to take into account non-local interactions. Since this theory is used not just to study superconductivity, but also in, for instance, biological physics and liquid crystals, we think that new interesting phenomena might be discovered within these disciplines through a similar generalization”, says Patric Holmvall.</div> <div> </div> <div>The new study has several connections to previous research at Chalmers. Patric Holmvall gives examples of the beautiful patterns found in liquid crystals, the organization of cells and bacteria in thin films, or structural coloration and iridescence in plants and animals, the latter caused by so-called photonic structures. These exemplify how surface interactions can trigger spontaneous pattern formation.</div> <div> </div> <div>In addition to Patric Holmvall, the Chalmers professors Mikael Fogelström and Tomas Löfwander, as well as Anton Vorontsov at Montana State University in the US, have co-authored the article “Phase crystals”.

Furthermore, an analysis of the free energy shows that it is mainly the phase rather than the amplitude which drives and characterizes the phase transition, in contrast to the traditional picture in superconductivity.</div> <div> </div> <h3 class="chalmersElement-H3">FACTS ABOUT SUPERCONDUCTORS</h3> <div>The superconducting ground state is characterized by the pair wave function, with an amplitude proportional to the pair density, and where variations in the phase are proportional to both the pair momentum and the electromagnetic potential. For a given system, the wave function assumes the amplitude and phase with the lowest free energy. Since pairs with a finite momentum (i.e. finite variations in the phase) lead to a kinetic energy, the ground state normally assumes a uniform phase without variations.

However, the content of dietary fibre and bioactive compounds, such as lignans, differ between cereals.  In a new study, researchers from Chalmers University of Technology show that wholegrain rye lowers serum LDL-cholesterol compared to wholegrain wheat.

In a new study, recently published in <em>The American Journal of Clinical Nutrition</em>, effects on metabolic parameters and risk factors was assessed between wholegrain wheat and rye for the first time, in subjects with so-called metabolic syndrome. People with metabolic syndrome have increased risk of cardiovascular disease and have elevated risk factors such as high blood pressure, high levels of blood cholesterol, obesity or abdominal obesity.</span></p> <div> </div> <h2 class="chalmersElement-H2"><span>​Lignan supplements to rye diet<br /></span></h2> <div> </div> <p class="chalmersElement-P">There is a difference of dietary fibre quality in wholegrain wheat and rye, and the cereals also have different contents of bioactive compounds. Rye has the highest content of both dietary fibres and bioactive compounds. For example, wholegrain rye is rich in lignans, so-called phytoestrogens, which are substances that are similar to the hormone oestrogen. </p> <div> </div> <p class="chalmersElement-P"> </p> <div> </div> <p class="chalmersElement-P">Various studies have shown that lignans have protective effects against the risk of developing hormone-dependent cancers, such as breast cancer and prostate cancer.

We added more lignans to the subjects' rye diet than any other study has done so far, and we measured the highest levels ever detected of enterolactone and enteradiol in humans. Despite this, we saw no effects on glucose turnover and metabolic risk factors.

Interestingly, only one of three enterotypes, (i.e. the sets of microorganisms found in the gut), was linked to lowering cholesterol levels.

This gave Green Cargo the clear sign to use stronger locomotives, with just a few restrictions from the Swedish Transport Administration.</b></p>​In the short term, it means millions of Swedish crowns in savings. In the longer term, it strengthens the competitiveness of train transport and enables the transfer of transport from road to rail. This means reduced carbon dioxide emissions for heavier transport. <div><br /></div> <div>The classification of railway vehicles affects the distances they can operate. The freight train operator Green Cargo needed to install locomotives with greater traction to get a reasonable economy in their freight transport. This meant that heavier locomotives with three-axis bogies would have to operate lanes that were normally operated by lighter, two-axis locomotives. However, the Swedish Transport Administration could not allow the heavier three-axis locomotives to traffic the lanes if the safety could not be guaranteed. The situation was so critical that it became a standing point at the meetings between the Swedish Transport Administration's Director General and Green Cargo's CEO. </div> <div><br /></div> <div>The classification of Green Cargo's three-axis locomotive meant that the locomotive was in a higher class than many lanes have been classified for, which could mean low operating speeds. For bridges, calculation tools are available to analyze the impact of specific vehicles, but for geotechnics the situation was more complicated. An analysis may require expensive and cumbersome soil samples and the remaining geotechnical restrictions were numerous. <img src="/SiteCollectionImages/Institutioner/M2/Nyheter/andersekberg.jpg" class="chalmersPosition-FloatRight" alt="Anders Ekberg" style="margin:5px" /><br /><br /></div> <div><span style="background-color:initial">Anders Ekberg is the director of the competence center Chalmers Railway Mechanics (Charmec). He says that the main challenge for Charmec was to understand the problem. But with the help of the contacts and the understanding built up between Charmec's partners, a solution was soon to be found. </span><br /></div> <div><br /></div> <div>“In a few meetings with intermediate analyzes, we were able to gain insight through the experience and knowledge we have gained in previous projects. Once the solution method was identified, we could relatively easily reach a solution using our numerical tools” says Anders Ekberg. </div> <h2 class="chalmersElement-H2"><span>In-house models from Chalmers provided a solution</span><span>​</span></h2> <div>The researchers from Chalmers proposed a comparative analysis between the stress resulting from a two-axis locomotive and that of a three-axis locomotive. Using in-house models their analysis showed that the marginally lower load per axis of the locomotive actually made the resulting stress in the ground lower for the three-axis locomotive despite this loco having an additional axle. To further analyze load, the Swedish Transport Administration conducted a dynamic analysis using software developed within Charmec.​</div> <div><br /></div> <div>“The analysis supported the conclusion that the locomotives provided a lower load on filling material and the underlying soil. The Swedish Transport Administration was now able to reduce the number of restrictions for Green Cargo's three-axis locomotives” says Ibrahim Coric head of Maintenance Railway system Permission Construction at the Swedish Transport Administration. </div> <div><br /></div> <div>Markus Gardbring is head of Green Cargo's operations and believes that it is of great importance for their operations. </div> <div><br /></div> <div>&quot;Green Cargo can now use stronger locomotives and demolish a large number of circulations for a number of larger customers, which leads to more efficient freight transport and is a prerequisite for us to be able to have more goods on the railway&quot; says Markus Gardbring. </div> <h2 class="chalmersElement-H2"><span>Contributes to reduced carbon dioxide emissions</span><span>​</span></h2> <div>Another benefit is that heavier locomotives with more redundant traction slip less, which reduces maintenance costs. Markus Gardbring also sees gains in the longer term. The Swedish rail network is being rebuilt to allow longer trains. The Swedish government has decided to reduce 70 percent of all carbon dioxide emissions for heavier transport by 2030. The segment that can easily be transferred to rail is intermodal goods. Longer trains are more cost-effective and a prerequisite for enabling competition with trucks in an extremely competitive market. The traction force of the locomotive will be decisive as the weight rather than the length becomes limiting for the number of wagons per train.</div> <h2 class="chalmersElement-H2">Read more about Charmec</h2> <div><a href="/en/departments/m2/news/Pages/Railway-researchers-awarded-for-societal-impact.aspx">Railway researchers awarded for societal impact​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/European-railway-harmony-better-for-the-climate.aspx">European railway harmony is better for the climate​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/Prediction-of-cracking-increases-the-railway%27s-reliability.aspx">Prediction of cracking increases the railway's reliability​</a><br /></div> <div><a href="/en/departments/m2/news/Pages/CHARMEC---A-prerequisite-for-a-functioning-railway.aspx">CHARMEC - A prerequisite for a functioning railway​</a><br /></div>Wed, 06 May 2020 00:00:00 +0200https://www.chalmers.se/en/news/Pages/Volunteers-produce-aprons-for-the-healthcare-system.aspxhttps://www.chalmers.se/en/news/Pages/Volunteers-produce-aprons-for-the-healthcare-system.aspxVolunteers produce aprons for the healthcare system<p><b>​In a room at Johanneberg Science Park on Chalmers campus, volunteers are making protective aprons for the healthcare system.

The new prosthesis does not feel like something I wear but as part of me. I use it all day, so for me it's so natural, it's not something I really think about.”</em></div> <div><br /></div> <div><strong style="background-color:initial">This makes the prosthesis unique</strong><br /></div></div> <div>The new concept of a neuromusculoskeletal prosthesis is unique in that it delivers several different features which have not been presented together in any other prosthetic technology in the world:</div> <div><ul><li>It has a direct connection to a person's nerves, muscles, and skeleton.</li> <li>It is mind-controlled and delivers sensations that are perceived by the user as arising from the missing hand.</li> <li>It is self-contained; all electronics needed are contained within the prosthesis, so patients do not need to carry additional equipment or batteries.</li> <li>It is safe and stable in the long-term; the technology has been used without interruption by patients during their everyday activities, without supervision from the researchers, and it is not restricted to confined or controlled environments.<br /></li></ul> <div><div>The newest part of the technology, the sensation of touch, is possible through stimulation of the nerves that used to be connected to the biological hand before the amputation. Force sensors located in the thumb of the prosthesis measure contact and pressure applied to an object while grasping. This information is transmitted to the patients’ nerves leading to their brains. Patients can thus feel when they are touching an object, its characteristics, and how hard they are pressing it, which is crucial for imitating a biological hand.</div> <div><br /></div> <div>“Currently, the sensors are not the obstacle for restoring sensation,” says Max Ortiz Catalan. “The challenge is creating neural interfaces that can seamlessly transmit large amounts of artificially collected information to the nervous system, in a way that the user can experience sensations naturally and effortlessly.”</div> <div><br /></div> <div>The implantation of this new technology took place at Sahlgrenska University Hospital, led by Professor Rickard Brånemark and Doctor Paolo Sassu. Over a million people worldwide suffer from limb loss, and the end goal for the research team, in collaboration with Integrum AB, is to develop a widely available product suitable for as many of these people as possible.</div> <div><br /></div> <div>“Right now, patients in Sweden are participating in the clinical validation of this new prosthetic technology for arm amputation,” says Max Ortiz Catalan. “We expect this system to become available outside Sweden within a couple of years, and we are also making considerable progress with a similar technology for leg prostheses, which we plan to implant in a first patient later this year.”</div></div></div> <div><br /><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Tankestyrda%20armproteser%20med%20känsel%20har%20blivit%20en%20del%20av%20vardagen/Max_och_patient_750x500px.jpg" class="chalmersPosition-FloatRight" alt="Max Ortiz Catalan with a patient" style="margin:5px" /><br /><br /><em>Max Ortiz Catalan in a follow up appointment with one of the patients, at the Chalmers Biomechatronics and Neurorehabilitation Laboratory.</em><br /></div> <div><h2 class="chalmersElement-H2">More about: How the technology works</h2> <div>The implant system for the arm prosthesis is called e-OPRA and is based on the OPRA implant system created by Integrum AB. The implant system anchors the prosthesis to the skeleton in the stump of the amputated limb, through a process called osseointegration (osseo = bone). Electrodes are implanted in muscles and nerves inside the amputation stump, and the e-OPRA system sends signals in both directions between the prosthesis and the brain, just like in a biological arm.</div> <div><br /></div> <div>The prosthesis is mind-controlled, via the electrical muscle and nerve signals sent through the arm stump and captured by the electrodes. The signals are passed into the implant, which goes through the skin and connects to the prosthesis. The signals are then interpreted by an embedded control system developed by the researchers. The control system is small enough to fit inside the prosthesis and it processes the signals using sophisticated artificial intelligence algorithms, resulting in control signals for the prosthetic hand's movements.</div> <div><br /></div> <div>The touch sensations arise from force sensors in the prosthetic thumb. The signals from the sensors are converted by the control system in the prosthesis into electrical signals which are sent to stimulate a nerve in the arm stump. The nerve leads to the brain, which then perceives the pressure levels against the hand.</div> <div><br /></div> <div>The neuromusculoskeletal implant can connect to any commercially available arm prosthesis, allowing them to operate more effectively.</div> <div><br /></div> <img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Tankestyrda%20armproteser%20med%20känsel%20har%20blivit%20en%20del%20av%20vardagen/Tankestyrd_protes_illustration_eng_400x311px.jpg" class="chalmersPosition-FloatRight" alt="An illustration of the mind-controlled prosthesis with sensation" style="margin:5px" /><div><div><span style="background-color:initial"><em>The neuromusculoskeletal prosthesis has a direct connection to a person's nerves, muscles and skeleton. The neural interfaces are electrodes wrapped around the severed nerves. The muscular interfaces consist of electrodes implanted on the biceps and triceps muscles. The skeletal interface comprises a titanium screw that is osseointegrated within the bone – meaning that the bone cells are directly attached to it, providing mechanical stability. Part of the skeletal interface extends out of the body through the skin and connects to the prosthetic arm. Electrical connectors embedded in the skeletal interface provide bidirectional communication between the prosthesis and the electrodes implanted in nerves and muscles.</em></span><br /></div></div> <div><br /></div> <div><h2 class="chalmersElement-H2">More about: How the artificial sensation is experienced</h2> <div>People who lose an arm or leg often experience phantom sensations, as if the missing body part remains although not physically present. When the force sensors in the prosthetic thumb react, the patients in the study feel that the sensation comes from their phantom hand. Precisely where on the phantom hand varies between patients, depending on which nerves in the stump receive the signals. The lowest level of pressure can be compared to touching the skin with the tip of a pencil. As the pressure increases, the feeling becomes stronger and increasingly ‘electric’.</div> <div>​<br /></div></div> <div><h2 class="chalmersElement-H2">More about: The research</h2> <div>The current study dealt with patients with above-elbow amputations, and this technology is close to becoming a finished product. The research team is working in parallel with a new system for amputations below the elbow. In those cases, instead of one large bone (humerus), there are two smaller bones (radius and ulna) to which the implant needs to be anchored. The group is also working on adapting the system for leg prostheses.</div> <div><br /></div> <div>In addition to applications within prosthetics, the permanent interface between human and machine provides entirely new opportunities for scientific research into how the human muscular and nervous systems work.</div> <div><br /></div> <div>Associate Professor Max Ortiz Catalan heads the<a href="http://www.bnl.chalmers.se/wordpress/" target="_blank"> Biomechatronics and Neurorehabilitation Laboratory​</a> at Chalmers University of Technology and is currently establishing the new Center for Bionics and Pain Research at Sahlgrenska University Hospital, in close collaboration with Chalmers and the University of Gothenburg, where this work will be further developed and clinically implemented.</div> <div><br /></div> <div>The research has been funded by the Promobilia Foundation, the IngaBritt and Arne Lundbergs Research Foundation, Region Västra Götaland (ALF grants), Vinnova, the Swedish Research Council, and the European Research Council.</div></div> <div><br /></div> <div>Chalmers University of Technology develops its collaboration with health care and medical research through the <a href="/en/areas-of-advance/health/Pages/default.aspx">Health Engineering Area of Advance​</a>.<br /></div> <div>​<br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Tankestyrda%20armproteser%20med%20känsel%20har%20blivit%20en%20del%20av%20vardagen/mindcontrolled_prosthesis_750px.jpg" class="chalmersPosition-FloatLeft" alt="The sensations of touch in a mind-controlled arm prosthesis " style="margin:5px" /><br /><br /><em>With the prosthesis, the patients can feel when they are holding an object, and how hard they are gripping, which is essential for imitating a biological hand.</em><br /></div> <div><h3 class="chalmersElement-H3">​<span>For more information, please contact</span></h3></div> <div><a href="/en/staff/Pages/max-jair-ortiz-catalan.aspx">Max Ortiz Catalan</a>, Department of Electrical Engineering, Chalmers University of Technology, Sweden, +46 70 846 10 65, <a href="mailto:%20maxo@chalmers.se%E2%80%8B">maxo@chalmers.se​​</a></div></div> <div><br /></div> <div><div><em>Text: Johanna Wilde<br /></em></div> <div><em>Portrait photo of Max Ortiz Catalan: Oscar Mattsson</em></div> <em> </em><div><em>Film and other photos: Johan Bodell</em></div> <em> </em><div><em>Illustration: Sara Manca /Yen Strandqvist</em></div></div>Wed, 29 Apr 2020 23:00:00 +0200https://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Testbed-for-electromobility-gets-575-million-SEK.aspxhttps://www.chalmers.se/en/areas-of-advance/Transport/news/Pages/Testbed-for-electromobility-gets-575-million-SEK.aspxTestbed for electromobility gets 575 million SEK<p><b>​One of Europe’s leading testbeds for electric and charging vehicles is now one step closer to realisation.
