MEMS Accelerometer with Z Axis Anchor Tracking
Abstract:
In some exemplary embodiments, a MEMS accelerometer includes a device wafer having a proof mass and a plurality of tracking anchor points attached to a substrate. Each tracking anchor is configured to deflect in response to asymmetrical deformation in the substrate, and transfer mechanical forces generated in response to the deflection to tilt the proof mass in a direction of the deformation.
