ABSTRACT:
A piezoelectric element for actuating a mechanical component, is proposed in which, with a multilayer structure of piezoelectric layers, the inner electrodes disposed between them can be subjected to an electrical voltage. Since the piezoelectric layers with the inner electrodes function like capacitors, a shunting resistor for a requisite electrical discharge is formed, preferably in the head or foot part, by forming resistor tracks out of a resistor layer.
