Abstract

The MEMS actuator is formed by a substrate, which surrounds a cavity; by a deformable structure suspended on the cavity; by an actuation structure formed by a first piezoelectric region of a first piezoelectric material, supported by the deformable structure and configured to cause a deformation of the deformable structure; and by a detection structure formed by a second piezoelectric region of a second piezoelectric material, supported by the deformable structure and configured to detect the deformation of the deformable structure.
