Abstract

According to various production methods for producing a piezoceramic multilayer actuator, in the course of the production method, multilayer locks (10) are electrochemically or mechanically processed in such a way that a recess structure is obtained. The lateral surfaces (22; 24) of the electrodes (20) inside these recesses are electrically insulated using the slip casting method in order to be able to contact the remaining electrodes by imprinting an outer metallization.
