  • Patent number: 10704909
    Abstract: A rotation rate sensor including a substrate having a principal plane of extension, and a structure movable with respect to the substrate; the structure being excitable from a neutral position into an oscillation having a movement component substantially parallel to a driving direction, which is substantially parallel to the principal plane of extension. To induce the oscillation, the rotation rate sensor includes a comb electrode moved along with the structure and a comb electrode fixed in position relative to the substrate. The excitation is produced by applying a voltage to the moving comb electrode and/or to the stationary comb electrode. Due to a rotation rate of the rotation rate sensor about an axis running substantially perpendicularly to the driving direction and substantially perpendicularly to the detection direction, a force applied to the structure with a force component along a detection direction substantially perpendicular to the driving direction is detectable.

    Abstract: A sensor structure includes a substrate having a main extension plane, a first seismic mass and a second seismic mass, the first and the second seismic masses being deflectable relative to the substrate along a direction of deflection essentially perpendicular to the main extension plane. The first and second seismic masses are coupled together via a rigid coupling rocker pivotable around a rocker axis parallel to the main extension plane. The first seismic mass is suspended from the substrate with the aid of a first suspension spring, and an essentially rigid first coupling bar is situated between the first suspension spring and the first seismic mass.

  • Patent number: 9266720
    Abstract: A component has at least one MEMS element and at least one cap made of a semiconductor material. The cap, in addition to its mechanical function as a terminus of a cavity and protection of the micromechanical structure, is provided with an electrical functionality. The micromechanical structure of the MEMS element of the component is situated in a cavity between a carrier and the cap, and includes at least one structural element which is deflectable out of the component plane within the cavity. The cap includes at least one section extending over the entire thickness of the cap, which is electrically insulated from the adjoining semiconductor material in such a way that it may be electrically contacted independently from the remaining sections of the cap.

  • Patent number: 9239339
    Abstract: An acceleration sensor has a substrate, a seismic mass and a detection unit. The seismic mass is configured to be deflected based on an external acceleration acting on the acceleration sensor, the deflection being in the form of a deflection motion with respect to the substrate along a deflection direction. The detection unit is configured to be deflected for the detection of a deflection of the seismic mass, the detection being in the form of a detection motion with respect to the substrate along a detection direction. The detection unit is connected to the seismic mass in such a way that the amplitude of the deflection motion along the deflection direction is greater than the amplitude of the detection motion along the detection direction.

    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.
