Claim Text:
1. An inertial measurement system, comprising: a device layer including a single proof-mass 3-axis accelerometer formed in an x-y plane, the single proof-mass 3-axis accelerometer suspended about a single, central anchor, the single proof-mass 3-axis accelerometer including separate x, y, and z-axis flexure bearings; wherein the x and y-axis flexure bearings are symmetrical about the single, central anchor; wherein the z-axis flexure bearing defines a pivot line offset from the single, central anchor; a cap wafer bonded to a first surface of the device layer; and a via wafer bonded to a second surface of the device layer, wherein the cap wafer and the via wafer are configured to encapsulate the single proof-mass 3-axis accelerometer.
