Abstract
An accelerometer for reducing undesired attraction or repulsion forces between a proof mass and a cover. An exemplary accelerometer includes a proof mass, a base, a flexure that flexibly attaches the proof mass to the base, at least one double-ended tuning fork (DETF) attached at one end to the proof mass and at another end to the base, and a housing structure that encloses the proof mass within a cavity. A layer of graphene is located on at least a portion of the nonconductive surfaces within the housing structure. The nonconductive surfaces include a surface on the proof mass, the housing structure, the base, the flexure, or the DETF. The layer of graphene is attached to a heat sink and/or to an electrical charge dissipation component.
