Title: ULTRASONIC ACTUATOR
Abstract:
The present invention provides a piezo actuator comprising a piezo material (1) having a first, top, surface, a second, bottom, surface, and a third, circumference, surface. The piezo material (1) has a polarity and the piezo material (1) comprises one or more mounting holes (3) in the piezo material (1), the one or more mounting holes (3) being positioned substantially central in at least the top surface or the bottom surface of the piezo material (1). The actuator also comprises at least one contact point (2) for contacting a load to be actuated, the at least one contact point (2) being positioned on the 10 third, circumference, surface of the piezo material (1), and a set of electrodes (6) being positioned on the top surface of the piezo material (1) and at least one electrode being positioned at the bottom surface of the piezo material (1).
