Piezoaktor mit neuartiger Kontaktierung und Herstellverfahren

摘要

During the operation of multilayered electric actuators fissures can occur in the metallizing strips due to voltages during polarization or during operation of the piezo electric actuator. The metallizing strips are fitted on the outer side of the actuator to enable contacting of the electrode layers. According to the invention, electrically conductive contact lugs are disposed on the metallizing strips leaving a protruding area, so that even if fissures occur they extend in the protruding area and are electrically bridged.
