Abstract:
A microactuator comprising:a substrate;a support fixed to an upper surface of the substrate;an elastic member connected to the support;an inertial member connected to the elastic member and spaced apart from the upper surface of the substrate by a predetermined distance, to be vibrated in a first direction parallel to the substrate;moving electrodes protruding from both sides of the inertial member in a second direction perpendicular to the first direction;fixed electrodes fixed on the substrate, facing the moving electrodes, spaced apart from the moving electrodes by a predetermined distance, and supplying an electrostatic repulsive force in the first direction to the moving electrodes when an electric potential is applied;common electrodes fixed on the substrate in the first direction, spaced apart from the moving electrodes and the fixed electrodes by a predetermined distance; anda power supply applying an electric potential to the moving electrodes, the fixed electrodes and the common electrodes.
