Patent ID: 8866364

Claim:
A piezo-electrically actuated micro-mechanical deformable member comprising: a corrugated longitudinal beam formed in a substrate, said beam having a first anchored end and a second end; a plurality of piezoelectric film (PZET) actuating segments formed in or on at least some grooves and ridges of the corrugated beam, the beam being configured to assume one of a number of different geometric configurations depending upon which of a corresponding set of electric actuation signals are applied to the PZET actuating segments, said electric actuation signals establishing corresponding electric fields in the associated PZET actuating segments to thereby deform the member; the beam, having said plurality of piezoelectric film (PZET) actuating segments, being configured to extend in length in response to a first set of said electric actuation signals; the beam, having said plurality of piezoelectric film (PZET) actuating segments, being configured to reduce in length in response to a second set of said electric actuation signals; the beam, having said plurality of piezoelectric film (PZET) actuating segments, being configured to deflect the second end of the beam in a first direction in response to a third set of said electric actuation signals; and the beam, having said plurality of piezoelectric film (PZET) actuating segments, being configured to deflect the second end of the beam in a second direction in response to a fourth set of said electric actuation signals.
