Abstract
In one embodiment, an accelerometer includes a suspension frame, a proof mass, and a plurality of flexures suspending the proof mass from the suspension frame. The flexures allow the proof mass to deflect in response to an acceleration along a sensitive axis of the accelerometer. Each flexure exhibits an initial spring rate along the sensitive axis of substantially zero.
