    Abstract: PROBLEM TO BE SOLVED: To provide a high performance inertial sensor capable of keeping SNR even in an environment having vibration disturbance.SOLUTION: The oscillatory type inertial sensor includes: two weights (excitation elements) 2 and 3; means (C1, C2, C3, C4, +Vd, and -Vd) for displacing them to the opposite phase; two sets of electrodes (C5, C6, C7, and C8) for detecting their displacements as capacitance variation; and a CV converting section 53 for converting the capacitance variation of the electrodes into an electric signal. One set of electrodes (for example, C5 and C8) whose electrostatic capacitances increase when the two weights 2 and 3 are displaced to the opposite phase are electrically interconnected, and one set of electrodes (for example, C6 and C7) whose electrostatic capacitances decrease in the same case are electrically interconnected, and each set is connected to the CV converting section 53.

    Abstract: The invention relates to a MEMS gyroscope for detecting rotational motions about an x-, y-, and/or z-axis, in particular a 3-D sensor, containing a substrate, several, at least two, preferably four, drive masses (2) that are movable radially with respect to a center and drive elements (7) for the oscillating vibration of the drive masses (2) in order to generate Coriolis forces on the drive masses (2) in the event of rotation of the substrate about the x-, y-, and/or z-axis. The oscillating drive masses (2) are connected to at least one further non-oscillating sensor mass (3) that however can be rotated about the x-, y-, and/or z-axis together with the oscillating drive masses (2) on the substrate. Sensor elements (9, 10) are used to detect deflections of the sensor mass (3) and/or drive masses (2) in relation to the substrate due to the generated Coriolis forces. At least two, preferably four anchors (5) are used to rotatably fasten the sensor mass (3) to the substrate by means of springs (4).
