ABSTRACT:
A piezoceramic multilayer actuator (10) has a plurality of piezoceramic layers (12), a security layer (20) and a plurality of inner electrodes (16, 18). The piezoceramic layers (12) has a piezoceramic first material sintered at a sintering temperature. The security layer (20) has a second material and is disposed between two piezoceramic layers (12). Each of the plurality of inner electrodes (16, 18) has a third material and is deposited between two piezoceramic layers (12). The degree of sintering of the second material is lower than the degree of sintering of the third material.
