Abstract

A problem of the surface friction is inevitable in the micro machines. However, the levitation by Meissner effect of high Tc superconductor gives a complete solution to the problem. The repulsive force between permanent magnets and superconductors is utilized to levitate and actuate micro structures without the surface friction. In this paper, a micro actuator using; Meissner effect of high Tc superconducting film (Meissnac) is proposed ; Meissnac is drived by the control of (Sugerconducting/ Normal) states of superconductor. The levitating force and the driving force are analyzed by the numerical method.
