Piezo Bender Actuator, made by co-firing multiple layers of piezoelectric ceramics, and can independently control the drive voltage of each layer of ceramics. The free end can bend to produce displacement, the amplitude and direction of displacement are functionally related to the applied voltage. The product specifications and performance parameters are benchmarked against the level of international companies, and mass production has been achieved.
