Publication number: 20240079972Abstract: The present invention relates to a shear deformation-type bimorphic piezoelectric actuator. The actuator includes at least a pair of shear deformation-type piezoelectric ceramic members which are polarized in the height direction thereof, coated with metal electrodes on both sides thereof and attached to opposite sides of a metal block to constitute a piezoelectric bimorph. The ceramic members are forced to undergo a face shear deformation or a resonance deformation upon receiving a driving voltage, whereby the metal block and the output head mounted thereon are driven to generate an elliptical motion, which in turn drives a rotor or a carriage to move. Taking advantage of the small dimension of the ceramic members and the enhanced displacement attributed to the piezoelectric bimorph structure, the piezoelectric actuator disclosed herein is suitable for manufacturing a miniature piezoelectric motor with high power output.Type: ApplicationFiled: April 27, 2023Publication date: March 7, 2024Inventors: Yung TING, Sheuan-Perng LIN, Suhail ABBAS, Chih-Hsuan YU
