Abstract (en)
[origin: DE102005046118A1] The actuator has a set of piezoelectric layers (3) between which layer electrodes (5, 6) are arranged. The layer electrodes are alternatively connected with connection electrodes (8, 9), and protective resistors (16) are provided between the connection electrodes and the layers electrodes. The protective resistors are formed by metallic layers between the piezoelectric layers, are arranged within the layer electrode and form films within the layer electrodes.
