Electrical sensors are used for many neurological or cardiological examinations. Here this is referred to as electroencephalography (EEG) or electrocardiography (ECG). For this purpose, electrodes are placed over the chest or on the head and electrical voltages are measured. This works quite well, but the propagation from the sources (the heart or the brain) to the sensors usually follows very "unusual" (material-dependent) paths. Alternatively, newly developed magnetic sensors can be used - here propagation takes place in a way that is noticeably more "material-independent" for most people. Due to the magnetic measurements, it might be possible in the future to perform much more accurate medical analyses, even without body contact - similar to the "tricorder" from "Star Trek".

In this talk, the Collaborative Research Center 1261 (Magnetoelectric Sensors: From Composite Materials to Biomagnetic Diagnostics), which deals with the research of novel magnetoelectric sensor systems, will be presented first. Then, some of the sensor principles designed to measure low-frequency, extremely weak magnetic fields in typical environments, i.e., without magnetic shielding and without expensive cooling systems, are presented. A brief outlook on biomedical applications for these types of sensors concludes the talk.

Gerhard Schmidt received his diploma in electrical engineering from the Technical University of Darmstadt in 1996 and received his Ph.D. in electrical engineer in 2001. He then worked as a researcher and group leader at Harman/Becker Automotive Systems in Ulm. From 2009 to 2010 he was head of the "Acoustic Speech Enhancement" department of SVOX in Ulm, Germany, as well as Industry Professor (part-time W3) at the Technical University of Darmstadt.

Since 2010, he has been Professor of Digital Signal Processing and Systems Theory at Christian Albrechts University in Kiel. His research interests include speech and audio processing, medical signal processing, and signal processing for underwater applications.
