Method for manufacturing piezo actuator, involves coupling piezoelectric inactive end area with assigned end surface of piezoelectric active area with formation of transition section between piezoelectric active and inactive end area

摘要

The method involves coupling a piezoelectric inactive end area with an assigned end surface of the piezoelectric active area (2) with formation of a transition section between the piezoelectric active area and the piezoelectric inactive end area. The piezoelectric inactive end area forms a defined discharge isolating area in the transition section. An independent claim is included for a piezo actuator with a piezo-electric active area.
