SHEAR MODE PHYSICAL DEFORMATION OF PIEZOELECTRIC MECHANISM

摘要

A piezoelectric mechanism includes first and second electrodes and a thin film sheet of piezoelectric material. The second electrode interdigitated in relation to the first electrode. The first and the second electrodes are embedded within the thin film sheet. The thin film sheet is polarized in a direction at least substantially perpendicular to a surface of the thin film sheet. The thin film sheet is to physically deform in a shear mode due to polarization of the thin film sheet at least substantially perpendicular to the surface of the thin film sheet, responsive to an electric field induced within the thin film sheet at least substantially parallel to the sheet via application of a voltage across the first and the second electrodes.
