REDUCING HYSTERESIS EFFECTS IN ACCELEROMETER

摘要

Techniques of manufacturing an accelerometer as disclosed herein include positioning an accelerometer between a first stator and a second stator, and the accelerometer comprises a plurality of features. In some examples, the plurality of features include a proof mass, a support structure defining a plane and configured to support the proof mass, a flexure configured to flexibly connect the proof mass to the support structure, and a plurality of raised pads, the plurality comprising at least one raised pad positioned between the flexure and an exterior of the support structure, wherein the at least one raised pad is configured to be isolatable. Techniques of manufacturing the accelerometer as disclosed herein further include compressing the first stator and the second stator onto the accelerometer, attaching a bellyband to the first stator and the second stator, and isolating the at least one raised pad.
