LARGER DISPLACEMENT OPERATING TYPE ACTUATOR

摘要

PURPOSE: A large displacement operating type actuator is provided to obtain a large displacement by arranging the actuator to operate at the region having a sub micro spacing. CONSTITUTION: A large displacement operating type actuator comprises a fixed electrode(100) for generating displacement at a fixed state; a movable electrode(200) protruded from the front end of a supporting beam(210) and coupled to the fixed electrode so as to generate displacement when the actuator is in operation; and a sub micro gap(400) formed between the electrodes in the portion where the supporting beam of the movable electrode is coupled, when the fixed electrode and the movable electrode are coupled with each other and operate.
