Abstract
A piezoactuator of multilayer design includes piezoelectric layers and electrode layers to form a stack. A predetermined breaking layer for the targeted origination and guiding of cracks is introduced between two adjacent electrode layers. The predetermined breaking layer has a barrier region, in which the formation of continuous electrically conductive paths or the formation of cracks leading through the barrier region is impeded.
