  • Patent number: 8461745
    Abstract: A piezoceramic surface actuator comprising multilayer plates each having a plurality of piezoceramic plates separated from one another by in each case a positive or negative electrode. The positive and negative electrodes alternate and are constructed integrally with the piezoceramic plates, and have 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 surface actuator that are opposite from one another. 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. The collector electrode surface in each case contacts the positive or negative electrodes of the neighboring multilayer plates.
