Prof. Dr.rer.nat. Sven Ingebrandt and his research team published the article “Contactless, Battery-free, and Stretchable Wearable for Continuous Recording of Seismocardiograms” in the journal ACS Applied Electronic Materials.. This article presents a study to enable remote measurement of mechanical cardiac activity using a contactless wearable patch and seismocardiography (SCG). Near-field communication (NFC) technology is used for power supply and wireless recording of SCG data. A separate electrocardiogram (ECG) is used as a reference. The results of this study show a good signal-to-noise ratio and a close correlation between SCG and ECG recordings. This method could become another valuable tool for cardiac monitoring in the future.

2D materials for high-volume production of electronic components

March 12th, 2021 | by

RWTH Professor Max Lemme and research partners publish in Journal “Nature Communications”

Professor Max Lemme, Chair of Electronic Devices at RWTH Aachen University, and his research partners publish a new method to integrate 2D materials into semiconductor manufacturing lines in the journal Nature Communications. The RWTH Aachen University researchers were supported by the KTH Royal Institute of Technology in Stockholm, the University of the Federal Armed Forces in Munich, AMO GmbH and Protemics GmbH. Currently, most experimental methods are not compatible with large-scale production. Moreover, they lead to significant degradation of the 2D material and its electronic properties. The method now being researched attempts to solve these problems. The two-dimensional materials will enable devices with significantly smaller sizes and enhanced functionalities compared to current silicon technologies. Overall, the range of potential applications extends from photonics to sensor technology and neuromorphic computing.

5 Years Helmholtz Institut Münster “Center for Ageing, Reliability and Lifetime Prediction of Electrochemical and Power Electronic Systems” (CARL)

March 11th, 2021 | by

Powerful battery technology is a core element that benefits us in many everyday applications. From smartphones to wireless work devices and electric vehicles – batteries are shaping our lives to an ever-increasing degree.
Around 2012, the idea was born to combine the expertise of Forschungszentrum Jülich, RWTH Aachen University, and the University of Münster in battery research. Thus, 5 years ago now, the Helmholtz Institute Münster “Ionics in Energy Storage” was founded, which has now become a respected part of the battery research landscape and leads to the continuous development of research infrastructures at the different locations. In Aachen, this is reflected by the construction of the “Center for Ageing, Reliability and Lifetime Prediction for Electrochemical and Power Electronic Systems (CARL)”.

IKS Startup – Elevear

March 8th, 2021 | by

Digital ear-opening – Hearing aids and other hearables often cause wearers to perceive their own voice in a distorted way, and chewing, swallowing, and even walking also generate unpleasant noise. The reason for this is the so-called occlusion effect, which occurs when headphones or hearing aids close off the auditory canal. This problem is addressed by the startup Elevear, which emerged from the Institute for Communication Systems and was successfully founded by Stefan Liebich, Johannes Fabry, Raphael Brandis, and Elfed Howells on February 4, 2021. Their Occlear® technology suppresses the occlusion effect and allows natural voice perception.
The project has already received the RWTH Innovation Award in 2019 and was accepted into the RWTH Incubation Program in January 2021 as one of twelve outstanding founding teams.

Improving Communication Systems Using Machine Learning

February 26th, 2021 | by

Prof. Dr. Laurent Schmalen from Karlsruhe Institute of Technology (KIT) contributes to our IKS event series with an online lecture entitled: „Improving Communication Systems Using Machine Learning“ Today, communication engineering still follows a model‐based design methodology influenced by the seminal design guidelines that were formulated by Claude Shannon in the 1940s. Such a model‐based approach may however not be suitable for many modern communication scenarios. In this talk, we show how we can augment communication systems using machine learning and in particular deep learning. In the first part of the talk, we show how machine learning can be used to optimize channel‐agnostic waveforms for an optical communication system. In the second part of the talk, we show how machine learning can be used to augment existing receiver algorithms and in particular channel decoding. We illustrate that short channel codes can be decoded with a performance close to the theoretical performance limits with significantly lower complexity than other state‐of‐the‐art methods

Hybrid Provision of Energy based on Reliabilty and Resiliancy via Integration of Dc Equipment

February 26th, 2021 | by

The project HYPERRIDE started on 1 October 2020. The four-year project contributes to the field implementation of DC and hybrid AC-DC grids. It will actively identify and provide solutions to overcome barriers to successful roll-out of new infrastructure concepts throughout Europe.

The Institute for Automation of Complex Power Systems (ACS) will concentrate its work on the development of automation services for the hybrid AC/DC grid. The focus here is on optimal power flow and fault management, as well as on the realization of a metering device specifically dedicated to DC technology: the DC Measurement Unit (DMU).

These solutions will be integrated into the open ICT platform, specifically tailored for integration with hybrid AC/DC distribution systems, and tested, among the others, in the demo site of the RWTH Aachen Campus Melaten.

You Never Walk Alone – How do I find a Study Group?

February 10th, 2021 | by

Image: Martin Braun

Most study groups are formed somewhat by chance: you probably sat next to each other in a lecture, chatted over coffee between lectures and exercises, or were in the same first-year tutorial. In the current situation, these opportunities no longer occur.

If you can now turn to a study group or fellow students from the last semesters, you are lucky. Start networking! Ask your fellow students if they are interested in forming a study group, working out a plan together on how to get through the exam phase separately but still together.

If you don’t have a study group yet, why not reach out in Zoom in one of your small group exercises (KGÜs) if someone would like to join up with you. Maybe someone from your first-year tutorial is interested? What other ways do you know of for finding a study group in times of Social Distancing?

RWTH and regional partners successful in the “Clusters4Future” ideas competition

Future clusters “NeuroSys” and “Hydrogen” to receive up to 90 million euros in funding from the BMBF

The German Federal Ministry of Education and Research (BMBF) has now published the winners of the “Clusters4Future” ideas competition. The BMBF is funding the research with up to 90 million euros. “Clusters4Future” is part of the German government’s High-Tech Strategy 2025. The open-topic competition focuses on regional innovation networks that combine the strengths of the players, tap into emerging fields of innovation and develop solutions for the challenges of the future.

“NeuroSys – Neuromorphic Hardware for Autonomous Artificial Intelligence Systems”

In addition to RWTH, the Forschungszentrum Jülich, AMO GmbH, IHK Aachen, the companies AixACCT Systems GmbH, AIXTRON SE, AppTek GmbH, ELMOS Semiconductor SE, RWTH Innovation GmbH and STAR Healthcare Management are involved in NeuroSys. In addition, the start-ups AiXscale Photonics UG, Black Semiconductor GmbH, Clinomic GmbH and Gremse-IT GmbH are involved. Professor Max Lemme from the Chair of Electronic Components and Managing Director of AMO GmbH will coordinate the work. The goal is the development of neuromorphic hardware for artificial intelligence applications and thus a technological independence for Germany and Europe. The Federal Ministry of Education and Research is providing up to 45 million euros for this purpose.

In Europe, there are only a few global corporations in the hardware and software sector. Technological independence is of strategic importance, as artificial intelligence will be the building block for the next global stage of development. However, not only future economic growth depends on this key technology, but also the management of major societal challenges such as climate change, health, work or mobility. At the same time, artificial intelligence (AI) brings new challenges. For example, training large neural networks based on modern graphics processing units (GPUs) with deep-learning methods causes high CO2 emissions, which further exacerbate the climate problem. GPU-based neural networks are therefore ecologically unsustainable.

Resource-saving neuromorphic hardware that makes neural networks more efficient and includes data security as a design component is therefore becoming the key to the widespread use of AI. This is especially true for areas of application in autonomous vehicles, medical technology and sensor networks for intelligent production or urban regions. Neuromorphic systems are modelled on the two basic building blocks of the human brain, the neurons and the synapses. By integrating new materials with specific properties, they can ideally perform resource-saving on-site processing of data by integrating new materials with certain properties. This is summarised under the keyword “memristive” – from the English “memory” for storage and “resistor” for electrical resistance.

Scientists at RWTH and Forschungszentrum Jülich have already been able to demonstrate the functionality of neuromorphic devices made of memristive materials. However, there are no pilot lines or production capacities worldwide for manufacturing or integrating neuromorphic chips on an industrial scale. Also, the system of hardware, design, algorithms and application-driven software must work together to exploit the major advantages of neuromorphic hardware. What is needed, therefore, is a paradigm shift with the opportunity to take a leading position in this new technology. NeuroSys wants to develop the decisive prerequisites here.

In addition to economic success, aspects such as the social benefits and ethics of artificial intelligence must be taken into account. These socio-economic framework conditions are essential for new technologies, especially with such a potential reach. They are therefore being researched in NeuroSys, also in order to develop recommendations for action for society and politics.

“The Future Cluster is a great opportunity for the Aachen-Jülich region, especially in connection with the structural change in the Rhenish Revier. We are stepping up to transfer excellent science into companies and start-ups in the region. Our vision is to set up a production line in the Aachen region. There, the co-integration of neuromorphic functions through new materials into conventional silicon technology will then take place” – Professor Lemme.

We also congratulate the Institute for Combustion Engines, since in addition to “NeuroSys”, the seven funded clusters include the future cluster “Hydrogen”, which will also be coordinated by RWTH Aachen University in the coming years. RWTH Aachen University and Forschungszentrum Jülich were applicants for the future cluster “Hydrogen”. So far, 24 institutes of the two research institutions are involved, in addition to 47 industrial partners and 16 other organizations.

Prof. Sauer Rector’s Delegate for Thailand

February 4th, 2021 | by

The Rector’s Office commissions RWTH professors as delegates for representative functions in specific areas or regions as well as individual tasks that are strategically important for the University. Thus, Prof. Sauer was appointed as the new Rectorate Representative for Thailand.

One reason for this is his long-standing commitment to the Thai-German Graduate School of Engineering. The TGGS and the ISEA are closely connected – this is also shown by the fact that the dean of the TGGS, Prof. Dr. -Ing. Nisai Fuengwarodsakul, completed his doctorate under Prof. De Doncker in 2007.
