We applied the technology of biomimetics to the development of an artificial muscle using a new theory of muscle contraction, and called it the electrostatic linear motor model. We designed and manufactured a fundamental electrostatic linear actuator that consists of a parallel-plate capacitor and a slider made of dielectric material. Since the actuator uses the water which fills the space between the two electrodes, it must be driven by an alternating current. The optimal frequency range for obtaining strong forces was from 5 to 10 kHz. We examined the influence of the applied voltage on the static force under the applied frequency of 10 kHz. The force increased in proportion to the second power of supply voltage. The force of 6.64 mN was obtained at 200 V.
