<P>PROBLEM TO BE SOLVED: To provide an electrostatic actuator accumulating mechanical energy in a driving process and converting it into a driving force to obtain a large output. <P>SOLUTION: An elastic member 22 whose one end is connected with an output portion 28 and a pair of driving electrodes formed of a first electrode 23 and a second electrode 27 to apply distortion to the elastic member 22 and accumulate energy are placed on a substrate 21. The pair of the driving electrodes, by applying voltage, generate an electrostatic attraction, relatively narrow a distance, and apply the distortion to the elastic member 22 to cause it to accumulate the energy. The electrodes are connected to means generating the electrostatic attraction. The elastic member generates the distortion by applying the voltage. The distortion of the elastic member 22 is released by releasing the voltage so that the output portion is driven by a force at the time when the elastic member is restored to an original length. <P>COPYRIGHT: (C)2012,JPO&INPIT |
