Abstract

A sensor system configured to amplify cantilever deflection, having: a reflective membrane connected to a cantilever, wherein the reflective membrane rotates more than the cantilever when the cantilever deflects. A sensor system, including: a cantilever having a first end and a second end, the first end being held at a first fixed location and the second end being free to move; and a reflective membrane having a first end and a second end, the first end being held at a second fixed location and the second end being attached to the cantilever.
