Patent ID: 8461745

Claim:
A piezoceramic surface actuator comprising: multi-layer plates each having a plurality of piezoceramic plates separated from one another by in each case a positive or negative electrode, wherein the positive and negative electrodes alternate and are constructed integrally with the piezoceramic plates, and having collector electrode surfaces for the positive and negative electrodes, which are connected to the associated positive or negative electrodes in a conducting manner and are arranged on two exterior sides of the multilayer plates that are opposite from one another, wherein the multilayer plates are plate-shaped and have a much greater width of the piezoceramic plates, defined by the distance between the opposite collector electrode surfaces, than the thickness of the multilayer plates, wherein the surface actuator is embedded in a plastic, and wherein a collector electrode surface is respectively provided for two mutually adjacent multilayer plates and in each case contacts the positive or negative electrodes of the neighboring multilayer plates.
