Abstract
A multilayer piezo actuator is specified, in which piezoelectric layers and electrode layers are arranged to form a stack. Electrical contact is made with the electrode layers via two external electrodes which consist of wires which are woven with one another. The external electrodes are in this case connected over their entire area to the side surfaces of the stack. A method is also specified for fitting an external electrode.
