Piezo actuator module with several piezo actuators connected in series

摘要

The piezoactuator module (1) has two piezoactuators (2,3) connected behind one another in mechanical direction of action. The piezo elements have exchangeable polarities with inner electrodes contacted by outer electrodes. The conductive bridges (6) are pressed at the outer electrodes between the outer electrodes by an electrically insulated connecting element for manufacturing an electrical contact to the outer electrodes. The connecting element is made of an electrically isolated metal or a polymer, particularly a Viton(RTM: A fluoroelastomer and has high heat resistance) ring.
