ABSTRACT:
A microelectromechanical micromotion amplifier generates a controlled lateral motion in response to a small deformation in the axial direction of a MEM beam or body. Lateral motion is produced by buckling of one or more long slender beams, the buckling motion being relatively large with respect to the axial motion which causes such lateral motion. The beams may be designed with a slight asymmetry to achieve gradual buckling in a desired direction. The device is capable of amplifying a driving motion in the range of 1-5 micrometers to produce a transverse motion in the range of 50-200 micrometers.
