  • Patent number: 7730783
    Abstract: An acceleration sensor includes a seismic mass which is suspended on springs above a substrate and is deflectable in a direction perpendicular to a surface of the substrate. In order to reduce deflections of the seismic mass along the surface of the substrate because of interference accelerations, which lead to a falsification of the measurements of the deflection of the seismic mass perpendicular to the surface of the substrate, the springs include two bending bars which are interconnected via crosspieces.

  • Publication number: 20100107762
    Abstract: An acceleration sensor is described that has a base substrate, a first electrode structure situated in stationary fashion relative to the base substrate, a sensor element having a first electrode area, and a spring device having at least one spring element. Via the spring element, the sensor element is coupled to the base substrate so that the sensor element is deflected relative to the base substrate as the result of an acceleration acting on the sensor element, thus changing the distance between the first electrode structure and the first electrode area. The sensor element and the first electrode structure are situated at least partially one over the other and are formed from a common functional layer.

  • Publication number: 20100058863
    Abstract: A device and manufacturing method for a rotation sensor device includes a holding device, an oscillating mass, and a spring, via which the oscillating mass is connected to the holding device. The spring is designed so that the oscillating mass can be set into an oscillating movement around an oscillation axis with respect to the holding device with the aid of a drive. The steps include: producing a layer sequence having a first layer made of semiconductor material and/or metal and a second layer made of semiconductor material and/or a metal, a boundary surface of the first layer, at least partially being covered by an insulating layer; structuring the spring out of the first layer; and structuring at least one oscillating mass subunit of the oscillating mass, which can be set into the oscillating movement around the oscillation axis with the aid of the drive, out of the second layer.

  • Publication number: 20100000321
    Abstract: A yaw rate sensor includes a drive mass element which is situated above a surface of a substrate and is drivable to vibrate by a drive device along a first axis extending along the surface, having a detection mass element, which is deflectable under the influence of a Coriolis force along a second axis perpendicular to the surface, and having a detection device by which the deflection of the detection mass element along the second axis is detectable. Due to the arrangement of the second axis perpendicular to the surface, the yaw rate sensor may be integrated into a chip together with additional yaw rate sensors suitable for detection of rotations about axes of rotation in other directions.

  • Patent number: 7523663
    Abstract: A micromechanical rotation rate sensor has a seismic mass and driving devices which cause a driving vibration of the seismic mass in a first direction x. The rotation rate sensor has measuring devices which measure a deflection of the seismic mass in a second direction y, and generate a deflection signal. The deflection includes a measurement deflection caused by a Coriolis force and an interference deflection, the interference deflection being phase-shifted with respect to the measurement deflection by 90°. Compensation devices are provided at the seismic mass to reduce the interference deflection. Regulation devices are provided, to which the deflection signal is supplied as an input variable, which demodulate an interference deflection signal from the deflection signal, and which generate a compensation signal from the interference deflection signal, which is supplied to the compensation devices.
