Abstract: A piezo actuator with an actuator body has at least one electrically conductive multi-layer film with a rigid electrical terminal element. The multi-layer film controls expansion and attraction of the actuator body. An electrical conduction layer of the multi-layer film has at least one recess to increase flexibility. The recesses in the conduction layer are, for example, photolitho-graphically produced.

Abstract: In the operation of piezoactuators of multilayer construction, during the polarizing or during the operation of the piezoactuator tears can arise, due to voltages, in the metallization strips that are attached to the actuator on the outside for contacting the electrode layers. It is inventively proposed to install electrically conductive contact lugs directly at the stack or on the metallization strips such that a laterally protruding region remains, so that, even given arising tears, these nevertheless extend in the protruding region of the contact lug, and the tears are electrically bridged. Electrical terminal elements are provided so as the project above or laterally at the contact lugs.

Abstract: A piezoelectric actuator, and method of producing same, wherein electrically conductive contact tabs are applied onto metallization strips in such a way that a projecting region remains, so that in the event of cracks nevertheless occurring, such cracks run in the projecting region of the contact tab and are bridged electrically.
