Abstract:
1. A micromechanical system, comprising: a substrate; a micromirror movable on a hinge attached to the substrate from a first position to a second position; a landing tip attached to the substrate, the micromirror making contact with the landing tip when it reaches the second position, the landing tip storing elastic strain energy when deformed by contact with the micromirror, and converting the elastic strain energy to kinetic energy to assist in pushing the micromirror away from itself when the micromirror moves from the second position back to the first position; anti-stiction material coated on the respective surfaces of the micromirror and the landing tip at least in areas where they contact; and whereby the combination of the stored elastic strain energy in the landing tip and the anti-stiction material prevent the micromirror from sticking to the landing tip when it moves from the second position to the first position.
