  • Patent number: 9816888
    Abstract: A sensor for detecting a position of an effective surface of the sensor includes a first magnetic field generator, a magnetic tunnel resistor, and a second magnetic field generator. The first magnetic field generator generates a first magnetic field that is oriented in an axis of a movement direction of the effective surface. The magnetic tunnel resistor is spaced from the first magnetic field generator in the extension of the axis. The magnetic tunnel resistor has a first magnetic layer, a second magnetic layer, and a tunnel barrier. The tunnel barrier is arranged between the first layer and the second layer, and the first layer is electrically insulated from the second layer. The second magnetic field generator is configured to generate a second magnetic field that is oriented transversally to the axis. The second magnetic field generator is oriented in a fixed manner relative to the tunnel resistor.

  • Patent number: 9588005
    Abstract: Measures are described which simplify the functional testing of a component having an MEMS element provided with a pressure-sensitive sensor diaphragm, and which allow a self-calibration of the component even after it is already in place, i.e., following the end of the production process. The component has a housing, in which are situated at least one MEMS element having a pressure-sensitive sensor diaphragm and a switching arrangement for detecting the diaphragm deflections as measuring signals; an arrangement for analyzing the measuring signals; and an arrangement for the defined excitation of the sensor diaphragm. The housing has at least one pressure connection port. The arrangement for exciting the sensor diaphragm includes at least one selectively actuable actuator component for generating defined pressure pulses that act on the sensor diaphragm.

  • Patent number: 9335203
    Abstract: A new signal acquisition concept is provided for MEMS components having a pressure-sensitive diaphragm element, which at least partially spans a pressure connection opening. This signal acquisition concept is distinguished by an especially high sensitivity. For this purpose, the MEMS component includes a resonant vibrator device having a vibrating element, which is suspended, capable of vibrating, within a closed cavity and is equipped with at least one drive electrode and at least one sensing electrode. The vibrating element of the resonant vibrator device is coupled mechanically to the diaphragm element, so that the vibrating element is deformed in the case of a diaphragm deflection.

  • Patent number: 9162873
    Abstract: A packaging concept for MEMS components having at least one diaphragm structure formed in the front side of the component is provided, according to which the MEMS component is mounted on a support which at least laterally delimits a cavity adjoining the diaphragm structure. In addition, at least one electrical feedthrough is formed in the support which allows electrical contacting of the MEMS component through the support. To achieve the largest possible rear volume for the diaphragm structure of the MEMS component for a given chip surface area, and also to simplify the processing of the support, according to the invention the electrical feedthroughs are integrated into the wall of the cavity adjoining the diaphragm structure, in that at least one section of such a feedthrough is implemented in the form of an electrically conductive coating of a side wall section of the cavity.

  • Patent number: 9131319
    Abstract: A capacitive MEMS microphone structure is provided, which micromechanical microphone structure of component is realized in a layer construction and includes: a diaphragm structure sensitive to sound pressure, which is deflectable in a direction perpendicular to the layer planes of the layer construction; an acoustically penetrable counter-element which has through holes and is formed above or below the diaphragm structure in the layer construction; and a capacitor system for detecting the excursions of the diaphragm structure. The diaphragm structure includes a structural element in the middle area of the diaphragm structure, which structural element projects perpendicularly from the diaphragm plane and which, depending on the degree of excursion of the diaphragm structure, variably extends into a correspondingly formed and positioned through hole in the counter-element.
