Patent ID: 7432629

Claim:
An articulated micro-electro-mechanical device suspended above a substrate comprising: a main platform having a longitudinal axis pivotable about first and second perpendicular axes; a first moveable actuator, one end of which is pivotally connected to the main platform, for pivoting the main platform about the first axis; a first actuating means for moving the first moveable actuator, thereby pivoting the main platform about the first axis; a second actuating means for pivoting the main platform about the second axis; a first torsional hinge pivotally connecting the main platform to the first moveable actuator defining a first spring constant relating to rotation about the second axis; a second torsional hinge pivotally connecting the main platform to the substrate defining a second spring constant relating to rotation about the second axis; and a third torsional hinge pivotally connecting the moveable actuator to the substrate defining a third spring constant relating to rotation about the second axis.
