ABSTRACT:
A piezoceramic multilayer actuator (10) has a plurality of piezoceramic layers (12) and a security layer (20) disposed between two piezoceramic layers (12). The piezoceramic layers (12) have a piezoceramic first material sintered at a sintering temperature. The security layer (20) has a second material (32) and particles (30) at least partially embedded in the second material (32). The particles (30) have a third material different from the first material and different from the second material (32). An adhesion between the third material and the first material is weaker than an adhesion between the second material (32) and the first material.
