Successful microactuators of simple mechanics on silicon chip are a prerequ
isite for monolithic microrobotic systems. Recent development in microelect
romechanical systems (MEMS) has led to the success in building new types of
microactuators. Based on the design of microgrippers and linear microvibro
motor, which were fabricated using surface micromachining, the analysis of
contact pairs and opposite movement forming of moving elements is given in
this paper. The source and mechanism of tribology of MEMS are discussed. As
sociated with the developing history of macro-machine, several research met
hods and possible existing problems about the tribology of surface IC proce
ssed MEMS are pointed out.
