Patent ID: 7952778

Claim:
A micro-electro-mechanical device comprising: a substrate with first and second supports extending upwardly therefrom; a tilting element pivotable about a first axis; first hinges, defining the first axis, extending from opposite sides of the tilting element; a rolling element, surrounding the tilting element and receiving the ends of the first hinges, pivotable about a second axis perpendicular to the first axis; second hinges, defining the second axis, extending from opposite ends of the rolling element, the outer ends of which are fixed to one of the first and second supports; a pedestal extending upwardly from the tilting element; a reflective body mounted on the pedestal; a first electrode mounted on the substrate along the second axis for rotating the tilting element and the reflective body about the first axis; and a second electrode mounted on the substrate including a first section along the second axis between the first electrode and the first support and a second section along the second axis between the first electrode and the second support, for rotating the rolling element, the tilting element and the reflective body about the second axis.
