Sensor for non-invasive measurement of sound, pressure and vibration on the human body

摘要

The invention relates to a sensor (1) for non-invasive measurement of sound, pressure and vibration on the human body which features a transducer in the form of a transducer membrane (23) to achieve a very good response characteristic coupled with low weight and small size. The transducer diaphragm (23) is preferably configured as a piezoelectric foil which converts the mechanical input variables into electrical signals which can be processed by means of processor units.
