    摘要: A MEMS device (20) includes a substrate (22), a proof mass (28), and a frame structure (30) laterally spaced apart from the proof mass (28). Compliant members (36) are coupled to the proof mass (28) and the frame structure (30) to retain the proof mass (28) suspended above the surface (26) of the substrate (22) without directly coupling the proof mass (28) to the substrate (22). Anchors (32) suspend the frame structure (30) above the surface (26) of the substrate (22) without directly coupling the structure (30) to the substrate (22), and retain the structure (30) immovable relative to the substrate (22) in a sense direction (42). The compliant members (36) enable movement of the proof mass (28) in the sense direction (42). Movable fingers (38) extending from the proof mass (28) are disposed between fixed fingers (46) extending from the frame structure (30) to form a differential capacitive structure.

    摘要: A MEMS device (20) includes a proof mass (32) coupled to and surrounding an immovable structure (30). The immovable structure (30) includes fixed fingers (36, 38) extending outwardly from a body (34) of the structure (30).
