Abstract

A capacitive measuring sensor which detects changes in an angle of electrode surfaces arranged at an acute angle to one another. The sensor outputs capacitive changes as a sensor signal. The sensor is preferably elongated and has at its end regions two fastening elements for connection to a body to be measured, two capacitor electrodes and two fastening elements. Changes in the angle of the capacitor electrodes is effected by displacement between the fastening points on the object to be measured.
