She is exceptionally talented in many respects. Dr. Theresa Götz, who indeed holds two doctorates – in physics and information science –  pursues her wide-ranging interests with both passion and dedication. And her career path reflects that variety: She had originally planned to become a hotel manager and chef with the ultimate aim of taking over her family’s restaurant. Then she won a youth research award, took part in the Fraunhofer Talent Academy, and completed her physics degree in record time. At the age of 26, she had successfully earned two doctorates, and she now works as chief scientist and deputy group manager of the Multimodal Human Sensing group at Fraunhofer IIS. We interviewed Theresa Götz about her career and her life.

Dr. Stephan Junger is head of the group "Optical sensors“ at Fraunhofer IIS

We’ve developed nanoSPECTRAL technology, which enables a large number of highly integrated spectral channels to be produced at very low cost. These production costs essentially remain constant, regardless of the number of spectral channels required. We achieve this by structuring metallic layers as part of the CMOS semiconductor fabrication process. Unlike with conventional optical filters, such as thin-film filters, no further processing steps are required to produce these optical nanostructures. #WeKnowHow

Christian Weigand’s professional interests center around the digitalization of healthcare. He is head of the Mobile Health Lab for mobile and digital medicine in Bamberg and CTO of the Digital Health Application Center (dmac). Addressing the question of whether physicians will visit us in our living rooms in the future in an interview on the Innovationskünstler*innen im Gespräch (“Innovation artists in conversation”) podcast from the Innovationskunst initiative, Weigand discussed innovations in the area of telemedicine that are intended to facilitate communication between patients and medical staff. The conversation focused on the security and availability of medical data, as well as the significance for research.

The team from Fraunhofer IIS and FAU with its “Lo3-ML” (Low-power low-memory low-cost ECG signal analysis using ML algorithms) project triumphed as one of the four winning teams in the “energy-efficient AI system” pilot innovation competition.

Computer architecture inspired by the human brain – to most people, this sounds rather abstract and removed from everyday life. Far from it: a research team from Fraunhofer IIS and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has developed neuromorphic hardware capable of detecting early signs of atrial fibrillation and considerably reducing the risk of stroke. In other words, this application has an entirely practical place in everyday life.

Group manager Dr. Matthias Völker and senior engineer Dr. Markus Stahl-Offergeld both work in the Smart Sensing and Electronics Division at Fraunhofer IIS. They are currently working on “KI-PREDICT”, a project funded by Germany’s Federal Ministry of Education and Research (BMBF) devoted to on-sensor data processing supported by AI functions. For this project, the two experts are focusing on the development of a “sensor interface ASIC” with integrated AI functions. One of the partners in the “KI-PREDICT” project is Rolf Slatter, the managing director of Sensitec GmbH since 2009. Sensitec is a global market leader in high-quality, innovative magnetic sensor solutions. We asked Matthias Völker, Markus Stahl-Offergeld, and Rolf Slatter to tell us about the project and their collaboration.

The purpose of Edge AI is to relocate artificial intelligence to where it is needed: end devices. For this to work, however, processing operations cannot be too energy-intensive. In the ECSEL projects ANDANTE and TEMPO, researchers at Fraunhofer IIS are paving the way for this emerging technology with the development of suitable chips, algorithms, and tools.

Some challenges are best faced shoulder to shoulder – like developing the chips, algorithms, and the hardware needed to integrate artificial intelligence directly into end devices, a paradigm also known as “Edge AI”. Marco Breiling, chief scientist at the Fraunhofer IIS Communication Systems division and Dr. Loreto Mateu, group manager at the Fraunhofer IIS Smart Sensing and Electronics division, talk about why their collaboration on Edge AI is so fruitful, and the benefits of working in an international team.

Im »Campus der Sinne Erlangen« wollen die Fraunhofer-Institute IIS und IVV sowie die Friedrich-Alexander-Universität Erlangen-Nürnberg gemeinsam mit Unternehmen menschliche Sinneserfahrungen erforschen und digital umsetzen.

For the fourth time in a year, Mr. Winter is sick in bed with an upset stomach. He had no way of knowing that the pasta sauce from the day before had gone bad: an infection he contracted a few years ago has robbed him of his senses of smell and taste. The Campus of the Senses is working on ways to digitally simulate the human senses. In our interview, the initiators of the Campus Prof. Albert Heuberger, Prof. Andrea Büttner and Dr. Jens-Uwe Garbas talk about assisting people with perception impairments and the difficulties inherent in the research.

The Internet of Things requires a lot of wireless receivers. How can we design them so that they save energy and don’t need much maintenance? Dr. Frank Oehler and Dr. Heinrich Milosiu have been dealing with this question since June 2007. Here is the development story of the RFicient® wireless receiver chip, which receives signals continuously, but consumes just one-thousandth of the electricity used by an LED.

The FitnessSHIRT accurately monitors parameters such as heart rate variability (HRV) and your pulse – without an additional strap. Our employee Heiko Wörrlein tested the shirt on a training run in the Tennenlohe Forest near Nürnberg, and talked with chief of development Christian Weigand to find out more about the shirt’s potential applications and the data it collects.

High-tech hospital beds to fight bedsores

Smart Sensing and Electronics / 8.3.2017

In Germany alone, some 400,000 people suffer from pressure ulcers or bedsores, each year. Bedsores develop after a short period in patients with insufficient mobility. The smart hospital bed detects the patient’s current position and suggests a new one chosen to relieve pressure.
