  • Piezoelectric motor using longitudinal and bending vibration modes
    Patent number: 12143036
    Abstract: A piezoelectric device includes a piezoresonator body and a set of electrodes disposed on the piezoresonator body. The piezoresonator body includes a bulk region and a contact element integral with and protruding from the bulk region, and further includes opposing first and second surfaces. A pair of excitation electrodes are disposed on the first surface. A common electrode is disposed on the second surface. The piezoresonator body is characterized by a longitudinal axis and a transverse axis, and further characterized by a natural resonant frequency (v1) of first-order longitudinal standing vibrations along the transverse axis and a natural resonant frequency (v2) of second-order bending standing vibrations along the longitudinal axis, with v1<v2?1.1v1.
