Abstract: A microgripper device includes a microactuator member and a microgripper member. The microactuator member includes an actuating portion adapted to output a driving force to the microgripper member. The microgripper member includes a main flame, an engaging portion, a pair of lateral shifting portions and a gripping portion. The main frame of the microgripper member mounts the microactuator member therein, and the engaging portion of the microgripper member connects to the actuating portion of the microactuating member. Each of the lateral shifting portions includes three connection portions linking the main frame, the engaging portion and the gripping respectively. The gripping portion of the microgripper member includes a pair of resilient arms and a pair of pivot portions. Each of the pivot portions connects to a first end of the corresponding resilient arm so that the second ends of the resilient arms are able to generate a gripping movement.

Abstract: A piezoelectric optical micro-switch structure includes a base unit, a first cantilevered arm base, a first piezoelectric controller, a second cantilevered arm base, a second piezoelectric controller and an optical reflector. The base unit bears the first cantilevered arm base and the second cantilevered arm base each of which has a first cantilevered arm and a second cantilevered arm. The first piezoelectric controller and the second piezoelectric controller are correspondingly attached to the first cantilevered arm and the second cantilevered arm and used to control bending angles of the first cantilevered arm and the second cantilevered arm. Connected between the first cantilevered arm and the second cantilevered arm is the optical reflector. When one of the first cantilevered arm and the second cantilevered arm is bent, the optical reflector can change a reflective direction of incident light.
