A first folded torsion spring (58) and a second folded torsion spring (60) interconnect the movable element (56) with the suspension anchor (54) to suspend the movable element (56) above the substrate (46). The folded torsion springs (58, 60) are each formed from multiple segments (76) that are linked together by bar elements (78) in a serpentine fashion. The folded torsion springs (58, 60) have an equivalent shape and are oriented relative to one another in rotational symmetry about a centroid (84) of the suspension anchor (54).

    摘要: A proof mass (11) for a MEMS device is provided herein. The proof mass comprises a base (13) comprising a semiconductor material, and at least one appendage (15) adjoined to said base by way of a stem (21). The appendage (15) comprises a metal (17) or other such material that may be disposed on a semiconductor material (19). The metal increases the total mass of the proof mass (11) as compared to a proof mass of similar dimensions made solely from semiconductor materials, without increasing the size of the proof mass. At the same time, the attachment of the appendage (15) by way of a stem (21) prevents stresses arising from CTE differentials in the appendage from being transmitted to the base, where they could contribute to temperature errors.

    摘要: A transducer (20) includes a movable element (24), a self-test actuator (22), and a sensing element (56, 58). The sensing element (56, 58) detects movement of the movable element (24) from a first position (96) to a second position (102) along an axis perpendicular to a plane of the sensing element (56, 58). The second position (102) results in an output signal (82) that simulates a free fall condition. A method (92) for testing a protection feature of a device (70) having the transducer (20) entails moving the movable element (24) to the first position (102) to produce a negative gravitational force detectable at the sensing element (56, 68), applying a signal (88) to the actuator (22) to move the movable element (24) to the second position (102) by the electrostatic force (100) , and ascertaining an enablement of the protection feature in response to the simulated free fall.
