    摘要: A MEMS sensor is disclosed. The MEMS sensor includes a MEMS structure and a substrate coupled to the MEMS structure. The substrate includes a layer of metal and a layer of dielectric material. The MEMS structure moves in response to an excitation. A first over-travel stop is formed on the substrate at a first distance from the MEMS structure. A second over-travel stop on the substrate at a second distance from the MEMS structure. At least one electrode on the substrate at a third distance from the MEMS structure. The first, second and third distances are all different.

    摘要: A magnetic field sensor includes a driving element through which an electric current circumnavigates the driving element. A Lorentz force acts on the driving element resulting in a torque about a first axis in response to a magnetic field along a second axis substantially parallel to a plane of a substrate. The driving element is coiled-shaped. A sensing element of the magnetic field sensor is configured to rotate about the first axis substantially parallel to the plane of the substrate in response to the magnetic field and a coupling element mechanically couples the driving element to the sensing element. The driving element, the sensing element, and the coupling element are disposed in the plane, substantially parallel to the substrate. At least two anchors are configured to connect the driving element, the sensing element, and the coupling element to the substrate.

    摘要: A sensor is disclosed. The sensor includes a substrate and a mechanical structure. The mechanical structure includes at least two proof masses including a first proof mass and a second proof mass. The mechanical structure also includes a flexible coupling between the at least two proof masses and the substrate. The at least two proof masses move in an anti-phase direction normal to the plane of the substrate in response to acceleration of the sensor normal to the plane and move in anti-phase in a direction parallel to the plane of the substrate in response to an acceleration of the sensor parallel to the plane. The at least two proof masses move in a direction parallel to the plane of the substrate in response to an acceleration of the sensor parallel to the plane.

    摘要: Facilitating self-calibration of a sensor device via modification of a sensitivity of the sensor device is presented herein. A sensor system can comprise a sensor component comprising a sensor that generates an output signal based on an external excitation of the sensor; a sensitivity modification component that modifies a sensitivity of the sensor by a defined amount; and a calibration component that measures a first output value of the output signal before a modification of the sensitivity by the defined amount, measures a second output value of the output signal after the modification of the sensitivity by the defined amount, and determines, based on a difference between the first output value and the second output value, an offset portion of the output signal. Further, the calibration component can modify, based on the offset portion, the output signal.
