Zusammenfassung:A piezo actuator, particularly a resonant vibration actuator for an ultrasonic motor, comprises a piezo element having a top surface and a bottom surface, a connection foil element comprising arms with flexure hinges for contacting the piezo element at different fixation positions located at node positions of a bending mode of the piezo element. The flexure hinges are such that the piezo element is allowed to move in a normal direction while being stiff in an orthogonal tangential direction.
