  • Patent number: 12072252
    Abstract: Aspects of the subject technology relate to a sensor device including a first cavity and a second cavity separated from the first cavity by a diaphragm. A first plate of the first cavity forms a first electrode of a capacitance. The diaphragm forms a second plate of the first cavity, which is the second electrode of the capacitance. The diaphragm is flexible and can deflect in response to an applied pressure.
    Type: Grant

  • Patent number: 11248974
    Abstract: Aspects of the subject technology relate to an apparatus including multiple cavities disposed adjacent to one another in a housing structure. The apparatus further includes a number of membranes, with each membrane disposed over a cavity to seal the cavity, and a sensor that can sense a deflection of a respective membrane associated with one of the cavities in response to an applied pressure. Each membrane is operable within a respective pressure range, and the applied pressure is within an operating range of the respective membrane.
