ABSTRACT:
A non-linear torsion hinge (12, 22) for a micro-mechanical device (10, 20) having a hinged movable element (11, 21). Each hinge (22) is comprised of two hinge strips (22a) spaced apart in the same plane, such that the axis of rotation of at least one of the hinge strips (22a) is different from the axis of rotation of the movable element (21). As a result, the hinge strip (22a) must elongate as it twists, thereby providing a greater restoring torque.
