Osteoporosis is one of the most common diseases worldwide: With increasing age, bone density decreases, the bone becomes porous and the risk of a bone fracture increases. On the left, a cross-section through an osteoporotic tibia (30% porosity); on the right, a healthy bone (5% porosity) in comparison.

Osteoporosis is one of the most common and expensive widespread diseases worldwide and increases the risk of suffering a bone fracture. Often the disease is detected late or not at all and remains untreated.

The research team consist of researchers from the Kiel University (CAU), namely: Professor Andreas Bahr the head of sensor system slectronics department at the institute of electrical engineering and information technology, Professor of Medical Physics Claus-Christian Glüer at the medical faculty of the CAU and head of the biomedical imaging section of the clinic for radiology and neuroradiology at the university medical center Schleswig-Holstein (UKSH), and software company sonoware GmbH. In the framework of the cooperation project it is planned to develop an ultrasound device that can be used to determine bone density and structure more accurately and more gently than the X-ray methods used to date. The new diagnostic device could thus be used in a more versatile way and help to identify osteoporosis diseases more quickly and comprehensively, according to the research team's goal.

The next step is to turn this patent-pending method into a fully functional prototype for medical use in general, internal medical or gynecology practices.

The project, which has now been launched, is being funded by the German Federal Ministry for Economic Affairs and Energy as a part of the Central Innovation Program for small and medium -sized enterprises (SMEs).

The full press report on the launch of the project can be found on the CAU's central website.

The chair of microwave engineering received the best student paper award at the International Microwave Filter Workshop (IMFW2021) in Perugia. In the paper „T-shaped Dual-Mode Waveguide Filters with Low Manufacturing Complexity for mm-Wave Applications", the authors Daniel Miek, Fynn Kamrath, Patrick Boe and Michael Höft showed that waveguide filters in the sub-terahertz frequency range can be realized by conventional milling techniques. These filters become increasingly important for future communication systems and sensors.

The German Federal Ministry of Education and Research is funding four German-wide research hubs looking into the next generation of mobile radio „6G“. The consortia consist of multiple universities and research institutes and combine unique knowledge for the development of new hard- and software, which will be also transferred to real applications in a later project phase. Stephan Pachnicke, Head of the Chair of Communications at the Institute of Electrical and Information Engineering, is participating in the „6G Research and Innovation Cluster“ (6G-RIC), which is led by the Fraunhofer Heinrich-Hertz-Institute (HHI). The goal of the cluster is to develop the next generation of mobile radio systems with open interfaces and breaking existing technological barriers. Also, an extensive test infrastructure will be created during the project. The total funding of the 6G-RIC project is 70 Million Euros over a period of 6 years.

The Research Minister, Mrs. Karliczek, commented:

„6G will be the mobile broadband technology of the future and will revolutionize the next century. 6G will be the central nervous system of our networked lives starting around 2030 and allow more than 100 times higher data rates than 5G combined with much higher energy efficiency and reliability. I am sure that the 6G research hubs will drive innovations in the communications fields of the future and will qualify future experts. They give us the unique opportunity to play as world-leaders for the future 6G mobile radio generation.“

Every year, the Gesellschaft für angewandte Signalverarbeitung (GaS) e.V. (Society for Applied Signal Processing) awards students in the field of digital signal processing and system theory who have completed outstanding theses. Particular attention is paid to the scientific and technical standards as well as the practical relevance of the work. In addition, the student's commitment and ability to work interdisciplinary and in a team are evaluated.

As part of this year's GaS Online General Assembly, Moritz Boueke, B.Sc., was awarded the title "Human Movement Classification using IMUs in Real-time" for his bachelor thesis. Mr. Boueke's work focused on the detection and differentiation of various everyday activities based on sensor data collected with inertial measurement units (IMUs). In our ageing society, neurodegenerative diseases such as Parkinson's are of high clinical relevance. In this context, the recording of movement patterns is an important tool in diagnosis and therapy. The trend is shifting from measurements in the clinical movement laboratory to measurements in the home environment, in which wearable sensors (so-called wearables) are used.

The identification of activities in the comparatively large amount of data is an important step in order to subsequently carry out targeted medical analyses, in which e.g. only stand-up processes are to be considered. As part of his work, Mr. Boueke has created extensive signal processing structures in the real-time framework KiRAT (Kiel Real-Time Application Toolkit), which lay a foundational foundation for this. This includes pre-processing of the sensor data, feature extraction, a decision tree for the actual classification and the preparation of intermediate results for visualization. As a result, activities such as "walking", "brushing" or "sitting down" can now be classified in real time with a state-of-the-art IMU system.

Neurogeriatrics, Department of Neurology, UKSH Campus Kiel, under the direction of Professor Walter Maetzler, acted as a medical project partner: "The award-winning work here is extremely innovative and user-oriented in an area that we physicians have paid too little attention to date: the natural home environment of our patients. With the presented work, Mr. Boueke succeeds in classifying relevant activities of daily life. This can be built on in many ways, with the ultimate goal of better diagnosis and treatment, especially of movement disorders. I would therefore like to congratulate Mr. Boueke and the supervisors on their work!" said Maetzler.

Congratulations from the institute.

In August, the Welt am Sonntag reported very positively about the E-PiCo master's degree program, which has meanwhile got off to a positive start, in its section on all aspects of training and studies. For example, the article begins with the words "The first European master's degree program in electromobility is jointly supported by four universities. The interest is enormous!"

In addition to the organizers of the study program, many of the first students naturally also have their say. If you are interested in reading the article, you can either have a look at the online version of the Welt am Sonntag or read the text here (in German).

Our university awards excellent achievements of female students in mathematics, IT, natural sciences and technology (known as the MINT subjects). This year Patricia Fuchs was awarded for her Bachelor thesis on the development and implementation of a magnetic heart axis estimation. We congratulate Patricia Fuchs to the EmpowerMINT award.

The thesis was supported with technical and medical expertise. In order to be able to compare the magnetically achieved results with conventional examinations (based on ECG), test persons were examined by Dr. Daniel Körbächer in his practice in Mönkeberg. The same persons were then magnetically measured at the Faculty of Engineering. Through this new method, the heart position of patients can be estimated more accurately and also in 3D (so far, this analysis is carried out only in the body level, i.e. in 2D). Ms. Fuchs was also supported by Prof. Frey, Head of Cardiology at the Heidelberg Hospital (and also a member of the SFB 1261). Erik Engelhardt and Gerhard Schmidt supervised the work on behalf of the Faculty of Engineering.

The picture shows Patrica Fuchs (center) and all supervisors (Daniel Körbächer, Erik Engelhardt, Gerhard Schmidt, Norbert Frey, from left).

At the beginning of the semester, the teaching program for the students of the master program E-PiCo in Kiel has started. This is already the second semester for the master students. We warmly welcome all newcomers here in Kiel.

The four-semester, English-language master's program E-PiCo is offered jointly by a consortium of partner universities: École Centrale de Nantes (France), Università degli Studi dell'Aquila (Italy), University Politehnica of Bucharest (Romania) and CAU. It is aimed at bachelor's graduates in electrical engineering or a similar field and includes charging and power optimization, energy management, battery life cycle, power electronics, mathematical system modeling and simulation, control and automation technology, optimization, among others. Various technological specializations of the partner universities and international industrial partners from the automotive, aerospace, logistics or transportation sectors complement the program.

The Research Minister is pleased that the European AI-NET project (AI-NET is abbreviating the English term "Accelerating Digital Transformation in Europe by Intelligent NETwork Automation") is now beginning. Prof. Pachnicke and his chair are involved in the large-scale project as part of the research of so-called resilient optical network structures (details).

Minister Karliczek commented: "I am pleased that the European AI-NET project is now beginning to explore the potential of artificial intelligence for automating the control of high-performance networks in order to guarantee network operation, optimize resource consumption and flexibly configure services. The three German project pillars will make an important contribution to this. The Federal Ministry of Education and Research is funding them with around 36 million euros for three years each."

A new lecture hall building is currently under construction at the faculty, as is the Center for Networked Sensor Systems. Since there are only a few people at the faculty at the moment due to the pandemic, we show a short video of the current state of construction here. In the area behind building D, a so-called construction road is currently being built, so that the corresponding construction materials can be easily brought to the faculty. Behind it the new lecture hall building will be built. The Center for Networked Sensor Systems will find its new home near Building B. It is good to see that construction is progressing well so far.
