Abstract

External electrodes on piezoceramic multilayer actuators, composed of a layer of a basic metallization applied to the ceramic material of the surface of a actuator, to which metallization there is joined by means of a joining layer a reinforcing layer to which a connecting wire is soldered, wherein the layer of basic metallization is structured by discontinuities or recesses.
