A6.1 - Magnetic Microsensors: Quo Vadis?

Jan Marien & Andreas Schuetze
Magnetic sensors are used for contactless and wearless detection of a wide range of magnetic fields. This includes extremely low fields of a few fT (10-15 T) generated by the activity of human brain cells up to hundreds of mT (0.1 T) of modern rare earth magnets. During the last 20 years magnetic sensors have become very popular for detecting different physical properties like electric current, mechanical position, speed, angle, rotational speed or the earth...
