Piezo Actuator Experience 
 
PI offers the largest selection of research- and industrial-reliability Piezo Actuators and Translators (linear actuators) worldwide. The following page shows but a few examples of the custom actuators developed over the last decades. The systems cited were designed for special custom applications and are not available off the shelf, some are subject to non-disclosure agreements and cannot be shown at all.
