  • PIEZOELECTRIC QUASI-RESONANCE LINEAR MOTORS BASED ON ACOUSTIC STANDING WAVES WITH COMBINED RESONATOR
    Publication number: 20130049536
    Abstract: A piezoelectric device includes a piezoresonator body (3) having opposing first and second surfaces and opposing third and fourth surfaces. The device also includes at least one common electrode (8) disposed on the second surface (15) and electrodes (4a, 4b) disposed on the first surface (14) in pairs along a first longitudinal axis. The device further includes contact elements (5) disposed on the third (16) and the fourth (17) surfaces at contact locations along the first longitudinal axis and aligned between each pair of excitation electrodes. In the device, the piezoelectric body has a first order natural resonance frequency (v1) along a second longitudinal axis and an even order natural resonance frequency (v2) along the first longitudinal axis, where a percent difference between v1 and v2 is greater than 0% and less than or equal to 20%.
