Zusammenfassung:The piezoceramic actuator (10) has alternating inner electrodes (30-37,39,40) extending inwards from the sides of the actuator, at which they are connected in parallel to external electrodes (24) on the opposite side of the actuator via respective contact surfaces. The inactive regions and the contact surfaces are offset by a given angle from one inner electrode to the next, each external electrode extending in a helix around the outside surface of the actuator. An Independent claim for a manufacturing method for a multi-layer piezoceramic actuator is also included.
