Piezoelectric Actuator with Outer Electrode

摘要

A piezoelectric actuator of a multilayer design which has a stack of piezoelectric layers and electrode layers arranged in between. The electrode layers are contacted by way of two outer electrodes, which have a multiplicity of wires. The outer electrodes are fastened in fastening regions on first side faces of the stack (11) and are led around the edge of the stack that is closest to the respective fastening region.
