    摘要: The invention relates to an acceleration sensor (400) comprising an excitation mass (420) having excitation electrodes (430), which excitation mass is movably mounted over a substrate (410) along a movement axis (x) and comprising detection electrodes (440) which are permanently connected to the substrate (410) and allocated to the excitation electrodes (430). A first group of pairings (450) of excitation electrode (430) and allocated detection electrodes (440) is suitable for deflecting the excitation mass (420) along the movement axis (x) in a first direction (460). A second group of pairings (450) of excitation electrodes (430) and allocated detection electrodes (440) is suitable for deflecting the excitation mass (420) along the movement axis (x) in a second direction (465), which is opposite the first direction (460). The number of pairings (450) in the first group is equal to the number of pairings (450) in the second group. The averaged distance between excitation electrodes (430) and detection electrodes (440) of the pairings (450) of the first group corresponds to the averaged distance between excitation electrodes (430) and detection electrodes (440) of the pairings (450) of the second group.

    摘要: [Object] To be capable of promptly performing a switching operation of a switch.[Solving Means] In a switching apparatus according to an embodiment of the present technology, a movable electrode includes a first movable electrode piece, a second movable electrode piece, and a movable contact point. A first fixed electrode includes first and second fixed electrode pieces, the first and second fixed electrode pieces facing each other with the first movable electrode piece disposed between the first and second fixed electrode pieces, the first fixed electrode piece facing the first movable electrode piece with a gap narrower than a gap between the second fixed electrode piece and the first movable electrode piece. A second fixed electrode includes third and fourth fixed electrode pieces, the third and fourth fixed electrode pieces facing each other with the second movable electrode piece disposed between the third and fourth fixed electrode pieces, the third fixed electrode piece facing the second movable electrode piece with a gap narrower than a gap between the fourth fixed electrode piece and the second movable electrode piece. A first fixed contact point is in contact with the movable contact point, the movable contact point moving in a first direction by an electrostatic attractive force between the movable electrode and the first fixed electrode. A second fixed contact point is in contact with the movable contact point, the movable contact point moving in a second direction opposite to the first direction by an electrostatic attractive force between the movable electrode and the second fixed electrode.

    摘要: An actuator comprising two devices each comprising an out-of-plane deformable element, said deformable element comprising a first fixed end anchored on a substrate and a second free end relative to the substrate, said device also comprising means to guide the second free end in in-plane translation along a first direction, the first deformable element being capable of deforming out-of-plane through application of a stimulus so that the second free end draws close to the first fixed end following in-plane translational movement. The actuator also comprises an element mobile in rotation about an axis orthogonal to the plane and mechanically linked to the free ends of the deformable elements, and a translationally mobile element mechanically linked to the rotationally mobile element.

    摘要: This document discusses, among other things, a cap wafer and a via wafer configured to encapsulate a single proof-mass 3-axis gyroscope formed in an x-y plane of a device layer. The single proof-mass 3-axis gyroscope can include a main proof-mass section suspended about a single, central anchor, the main proof-mass section including a radial portion extending outward towards an edge of the 3-axis gyroscope sensor, a central suspension system configured to suspend the 3-axis gyroscope from the single, central anchor, and a drive electrode including a moving portion and a stationary portion, the moving portion coupled to the radial portion, wherein the drive electrode and the central suspension system are configured to oscillate the 3-axis gyroscope about a z-axis normal to the x-y plane at a drive frequency.

    摘要: An assembly (20) includes a MEMS die (22) having a pressure transducer device (40) formed on a substrate (44) and a cap layer (38). A packaging process (74) entails forming the device (40) on the substrate, creating an aperture (70) through a back side (58) of the substrate underlying a diaphragm (46) of the device (40), and coupling a cap layer (38) to the front side of the substrate overlying the device. A trench (54) is produced extending through both the cap layer and the substrate, and the trench surrounds a cantilevered platform (48) at which the diaphragm resides. The MEMS die is suspended above a substrate (26) so that a clearance space (60) is formed between the cantilevered platform and the substrate. The diaphragm is exposed to an external environment (68) via the aperture, the clearance space, and an external port.
