Biosignal Measurement Techniques

Working Group 8.22

Development of highly sensitive measurement methods for biomagnetic signals and spin precession

Profile

Die Arbeitsgruppe „Messtechnik für Biosignale“ beschäftigt sich mit der Entwicklung von neuartigen biomagnetischen Messverfahren. Dafür werden hochsensitive magnetische SQUID-Messsysteme eingesetzt und weiterentwickelt. Weiterhin beschäftigen wir uns mit der Optimierung von magnetischen Schirmungen und betreiben den weltweit am besten magnetisch geschirmten begehbaren Raum BMSR-2.
