Recently Yano proposed a new theory of muscle contraction, termed Electrostatic linear motor model. His theory has not yet been authorized. The principle of this model, however, is very attractive for realizing an artificial muscle. Because it can explain almost all phenomena of muscle contraction consistently. We, therefore, started developing an electrostatic linear motor as a biomimicking skeletal muscle.The fundamental motor unit consists of a parallel plate capacitor and a slider made of dielectric material. Based on this model, we derived the theoretical formulae for the various characteristics of the motor.Following facts were revealed through the experiments using the fundamental model of the motor.1)The theoretical formulae agree well with the experimental results.2)The thrust can be increased by decreasing the thickness of the motor.3)Integration of the micrometer sized motor units is very effective to increase the thrust.4)The coefficient of kinetic friction between the stator and the slider should be less than one.Base on these results, we designed the simple model to know the feasibility of this motor. This linear motor is expected to be able to use in practice.

最近矢野提出了一种新的肌肉收缩理论，称为静电直线电机模型。他的理论尚未得到证实。然而，该模型的原理对于实现人造肌肉非常有吸引力。因为它可以一致地解释几乎所有的肌肉收缩现象。因此，我们开始开发一种静电直线电机作为仿生骨骼肌。基本电机单元由平行板电容器和由介电材料制成的滑块组成。基于这个模型，本文导出了该电机各种特性的理论公式，并利用该电机的基本模型进行了实验研究，结果表明：1）理论公式与实验结果符合得很好; 2）减小电机的厚度可以提高推力; 3）将微米级的电机单元集成在一起可以有效地提高推力。在此基础上，设计了该电机的简单模型，验证了该电机的可行性。这种直线电机有望能够在实际中使用。
