Abstract:
A microelectromechanical system comprising:a substrate; a platform including first, second and third attachment points, said platform being pivotably attached to said substrate at the first attachment point; a first lever arm attached to said platform at the second attachment point of said platform and pivotably attached to said substrate at a first anchor point on said substrate; and a second lever arm attached to said platform at the third attachment point of said platform and pivotably attached to said substrate at a second anchor point on said substrate; said first attachment paint being located on the some side of a line intersecting said second and third attachment points as a side of said line on which said first and second anchor points are located when said platform is in a non-tilted orientation with respect to said substrate; said first and second lever arms being separately pivotable about said first and second anchor points, respectively, by unequal angular amounts to tilt said platform with respect to said substrate with at least two degrees of freedom, wherein each of said first and second lever arms are pivotable in response to an actuation force mechanically coupled thereto and generated without utilizing any portion of said lever arms and said platform.
