A Broad Range of New Clinical Applications for a Magnetic Sensor Measuring Distance on the Human Body

This paper describes the features of a magnetic distance meter initially intended to detect sleep-related breathing efforts through the recording and analysis of jaw movements. The design of the device made it a very sensitive, non-invasive, wearable and easy-to-use motion detector. As such, it rapidly became an interesting equipment in wholly different clinical domains like radiotherapy and biomechanics. The new prospects offered by this magnetic motion-sensing solution in various clinical applications are presented and discussed here.
