Zusammenfassung:A piezo actuator includes a piezo motor element having a top and a bottom surface, and a connection element having arms with flexure hinges for contacting the piezo motor element at different fixation positions located at node positions of a bending mode of the piezo motor element. The flexure hinges are such that the piezo motor element is allowed to move in the normal direction and the flexure hinges being stiff in the tangential direction, wherein the flexure arms are fixed to the piezo motor element with a fixation means.
