Abstract:
1. A proof-mass for an accelerometer, the proof mass comprising: a center portion configured to anchor the proof-mass to an adjacent layer; a first z-axis portion of the proof mass configured to rotate about a first axis using a first hinge, the first axis parallel to an x-y plane orthogonal to a z-axis; a second z-axis portion of the proof mass configured to rotate about a second axis using a second hinge, the second axis parallel to the x-y plane; wherein the first z-axis portion is configured to rotate independent of the second z-axis portion; and wherein the central portion includes an anchor portion and an x-axis proof mass portion, the x-axis proof mass portion configured to deflect, with respect to the anchor portion, in response to an acceleration of the proof mass along the x-axis.
