The novel drive principle, that makes electrostatic force collaborate with the non-linear spring, and the electrostatic microactuator driven by that principle were proposed. By the detailed simulation using the finite element method, the electrostatic microactuators which had the output of 931 times higher than the previous one were designed, and it was seen that the output of more than 10, 000 times higher was possible if shape and dimensions of stricture, and micromachining technique were improved. They proved the excellence of novel drive principle and structure of the microactuator. In addition, the problems on the fabrication were clarified experimentally by trial manufacture.

提出了静电力与非线性弹簧协同作用的新型驱动原理，以及基于该原理的静电微驱动器。通过有限元模拟，设计出了输出功率提高931倍的静电微致动器，并指出如果改进结构的形状、尺寸和微加工工艺，输出功率将提高1万倍以上。证明了该微驱动器新颖的驱动原理和结构的优越性。此外，还通过试制，对制作中的问题进行了实验研究。
