Abstract:
1. An electromechanical system, comprising: a substrate comprising a surface region; a flexible member comprising a first end coupled to the surface region of the substrate, the flexible member comprising a second end and a length defined between the first end and the second end; a base region within a first portion of the flexible member, the base region being defined from the first end to a first predetermined portion of the length of the flexible member, the base region being characterized by at least a first cross-sectional area, the first cross-sectional area being parallel to the surface region of the substrate; a tip region within a second portion of the flexible member, the tip region being defined from the second end to a second predetermined portion of the length of the flexible member, the tip region being characterized by at least a second cross-sectional area, the second cross-sectional area being parallel to the surface region of the substrate and being smaller than the first cross-sectional area; and a reflective member coupled to the flexible member, the reflective member comprising a reflective surface and a backside region, the backside region being coupled to the second end of the flexible member, the reflective surface being substantially parallel to the surface region while the reflective member is in a first state and being substantially non-parallel to the surface region while the reflective member is in a second state; whereupon the flexible member moves from a first position characterized by the first state to a second position characterized by the second state, the movement of the flexible member from the first position to the second position being constrained to lie in a first plane defined by an axis parallel to the length of the flexible member and an axis parallel to the surface region, wherein an angle between the reflective member in the first state and the reflective member in the second state, measured in the first plane, is less than 12°.
