    Abstract: A device includes a microelectromechanical system (MEMS) sensor die comprising a deformable membrane, a MEMS heating element, and a substrate. The MEMS heating element is integrated within a same layer and a same plane as the deformable membrane. The MEMS heating element surrounds the deformable membrane and is separated from the deformable membrane through a trench. The MEMS heating element is configured to generate heat to heat up the deformable membrane. The substrate is coupled to the deformable membrane.

    Abstract: A pressure sensor comprises a first substrate containing a processing circuit integrated thereon and a cap attached to the first substrate. The cap includes a container, a holder, and one or more suspension elements for suspending the container from the holder. The container includes a cavity and a deformable membrane separating the cavity and a port open to an outside of the pressure sensor. The container is suspended from the holder such that the deformable membrane faces the first substrate and such that a gap is provided between the deformable membrane and the first substrate which gap contributes to the port. Sensing means are provided for converting a response of the deformable membrane to pressure at the port into a signal capable of being processed by the processing circuit.

    Abstract: A pressure sensor comprises a polysilicon sensing membrane. The pressure sensor further includes one or more polysilicon electrodes disposed over a silicon substrate. The sensor also includes one or more polysilicon routing layers that electrically connects electrodes of the one or more polysilicon electrodes to one another, wherein the polysilicon sensing membrane deforms responsive to a stimuli and changes a capacitance between the polysilicon sensing membrane and the one or more polysilicon electrodes. The sensor also includes one or more vacuum cavities positioned between the polysilicon sensing membrane and the one or more polysilicon electrodes.

    Abstract: A device includes a sensor die, an electrical coupling, a substrate, a liquid detection unit, and a housing unit. The sensor die is coupled to the substrate via the electrical coupling. The liquid detection unit electrically is coupled to the sensor die. The housing unit and the substrate are configured to house the sensor die, the liquid detection unit, and the electrical coupling. The housing unit comprises an opening that exposes the sensor die to an environment external to the housing unit. The liquid detection unit detects presence of liquid within an interior environment of the housing unit. In some embodiments, the device further includes a gel filled within the interior environment of the housing unit covering the sensor die and the substrate. The gel, e.g., silicone, fluoro silicone, etc., is configured to protect the sensor die, the electrical coupling, and the substrate from exposure to the liquid.
