Abstract(in English) | The potential benefits of piezoelectric bimorph actuator are their simplified structure, faster response, and relatively large displacement. A LiNbO_3 crystal plate is produced in oppositely-polarized layers with heated slightly below the Curie temperature, and the LiNbO_3 bimorph can show no hysteresis and no creep. We study the actuator of the oppositely-polarized 140° rotated Y plate. Its size is 30×10×0.2(mm). The fundamental characteristics of the actuator were electrically and optically measured and analyzed by FEM and equivalent circuit model. For the servo accelerometer, the additional mass, the integrated displacement sensor and the feedback circuit were examined to increase the sensitivity. |
