Piezokeramische Vielschichtaktoren sowie ein Verfahren zu ihrer Herstellung

摘要

The device has inner electrodes (3) alternately on opposite sides and connected on each surface by an outer electrode consisting of at least one basic metallisation coating on the inactive area (14) of the actuator for connection via a connection layer to a strengthening layer to which a voltage supply connection can be soldered. The actuator surface in the active area has a structure (18) produced by removal of material and the basic metallisation is only applied to the remaining surface (10) left by the structuring. Independent claims are also included for the following: a method of manufacturing a piezoceramic multilayer actuator.
