1. A microengine batch fabricated by polysilicon surface micromachining techniques, comprising:

  • a substrate base;

    a mechanical output gear made rotatably secured by a central flanged restraining hub formed on and attached to said substrate base, said gear having a center and an outer perimeter, said gear for providing direct rotational power to a micromechanism;

    a linear actuator means formed on said substrate base and linked to said mechanical output gear near said outer perimeter by a linkage means, said linear actuator means for causing rotation of said mechanical output gear; and

    a linkage means for linking said linear actuator means to said mechanical output gear wherein said linkage means is rotatably connected to said gear between the center and the outer perimeter of said gear.
