Disclosed is a piezo-electrically actuated micro-mechanical deformable member comprising a corrugated longitudinal beam (521) formed in a substrate, and having a first anchored end (502) and a second end (509), as well as a plurality of piezoelectric film (PZET) actuating segments (522, 523, 524) formed in or on at least some grooves and ridges of the corrugated beam, the beam (521) being configured to assume one of a number of different geometric configurations depending upon which of a corresponding set of electric actuation signals (105) are applied to the PZET elements, the electric actuation signals establishing corresponding electric fields in the associated PZET segments to thereby deform the member. |
