Abstract:
1. A translation device for a microelectromechanical system, said device comprising, implemented in a microelectromechanical architecture: first and second linear stator assemblies disposed in spaced relation and defining an elongate channel therebetween, each of said stator assemblies comprising a plurality of stators arranged in a row along said channel so as to face said channel; a shuttle member disposed in said channel between said stator assemblies for translating movement therealong, said shuttle member including a plurality of rotors extending outwardly from opposing sides thereof facing said stator assemblies in spaced relation to the stators of said stator assemblies, said shuttle being grounded and including a mounting area for an object to be translated; a plurality of electrical lines individually connected to alternate stators of a plurality of groups of the stators of said first and second stator assemblies; and current supply means for sequentially supplying current through said electrical lines to said alternate stators so as to effect charging of the stators in a predetermined sequence such as to produce a tangential capacitive force causing translating movement of the shuttle along said channel; said device further comprising a pair of rails disposed on opposite sides of said channel so as to define side walls of said channel, said shuttle being grounded through contact with said side walls.
