Title: Method for operating a piezoceramic sensor and circuit for carrying out the method

Abstract: In the case of a method for operating a piezoceramic sensor with an evaluation electrode, an electrical signal generated by the piezoceramic sensor at the evaluation electrode is evaluated to determine an actuating state of the piezoceramic sensor. The evaluation electrode is subjected to a predetermined reference potential during recurring time intervals, in order to reference the evaluation electrode with the reference potential during these time intervals.
