Micromechanical piezoelectric actuators for implementing large forces and deflections

摘要

A MEMS includes a diaphragm, a stroke structure coupled to the diaphragm, and at least two piezoelectric actuators coupled to a plurality of mutually spaced-apart contact points of the stroke structure via a plurality of mutually spaced-apart connecting elements, the at least two piezoelectric actuators being configured to cause a stroke movement of the stroke structure so as to deflect the diaphragm.
