Abstract:
1. A piezoceramic multilayer actuator, comprising: a plurality of piezoceramic layers and a plurality of electrodes, which are disposed one above the other in a stacking direction such that the electrodes are located on opposing sides of the piezoceramic layers, at least one micromechanical relief zone, within which mechanical stresses in the piezoceramic multilayer actuator can be reduced, wherein a number of sections of the piezoceramic multilayer actuator without a micromechanical relief zone have an insulation layer, so that the section of the piezoceramic multilayer actuator is at least one of electrically, chemically and thermally insulated from a medium surrounding the piezoceramic multilayer actuator.
