Abstract:
A piezoelectric actuator includes a fixed body, a movable body arranged to face the fixed body, and a plurality of piezoelectric elements arranged between the fixed body and the movable body and operating in a shearing mode. Each piezoelectric element having one end fixed to the fixed body and another end contacting the movable body, wherein a direction of polarization of each of the plurality of piezoelectric elements is different from each other.
