A micro feeding system that integrates energy conversion device with mechanical transmission for obtaining planar linear positioning motions is proposed. The design of the proposed micro feeding system will be incorporated with the positioning device with bistable mechanism. The positioning device, with bistable mechanism with the function of un-powered locking and anti-disturbance will be the most important characteristic of the micro feeding system. All micro devices are fabricated through the surface micro machining and the experiment results demonstrate that the proposed micro feeding system is practicable initially. Furthermore, the proposed application of the micro feeding system is also implemented. The micro feeding system successfully lifts up a mirror and hold in place without external power. More importantly, the positioning device can work repeatedly so that the micro feeding system can hold the mirror in place with various tilting angles.
