    摘要： The invention relates to a rotational speed sensor comprising the features of the generic part of the main claim. The inventive rotational speed sensor is provided with force-transducing means. The invention is characterized in that the effective force transduced by said means is provided with a certain frequency such that the frequency of the transduced effective force represents an integer multiple of the oscillation frequency of the driving element parallel to the x axis.

    摘要： The present invention relates to a rotation-rate sensor having a drive mass element (13) which is arranged above a surface of a substrate and can be caused to oscillate by means of a drive device (18) along a first axis (y) which runs along the surface, having a detection mass element (14) which can be deflected under the influence of Coriolis force along a second axis (z) which runs at right angles to the surface, and having a detection device which can detect the deflection of the detection mass element (14) along the second axis (z). The arrangement of the second axis (z) at right angles to the surface allows the rotation-rate sensor to be integrated on a chip together with further rotation-rate sensors which are suitable for detection of rotations about rotation axes in other directions.

    摘要： The invention relates to a micromechanic acceleration sensor, comprising a substrate (1), an elastic membrane (5), which extends in parallel to the substrate plane, is partially connected to the substrate and comprises a surface region, which can be deflected perpendicular to the substrate plane. The invention further comprises a seismic mass (6), wherein the center of gravity thereof is outside of the plane of the elastic membrane (5). The seismic mass (6) extends at a distance across substrate regions, which are located outside of the region of the elastic membrane (5) and comprise an arrangement made of a plurality of electrodes (3a, 3b, 3c, 3d), which form a capacitor with opposing regions of the seismic mass (6) in a circuit. In the central region, the seismic mass (6) is fastened in the surface region of the elastic membrane (5), which can be deflected perpendicular to the substrate plane, to the elastic membrane (5).
