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 device includes a housing unit with an internal volume. The device further includes a sensor coupled to a substrate via an electrical coupling, wherein the sensor is disposed within the internal volume of the housing unit, and wherein the sensor is in communication with an external environment of the housing unit from a side other than a side associated with the substrate. The device also includes a moisture detection unit electrically coupled to the sensor, wherein the moisture detection unit comprises at least two looped wires forming electrodes, and wherein the moisture detection unit is configured to detect presence of a moisture within an interior environment of the housing unit by measuring a capacitance between the electrodes and by detecting a change between the measured capacitance and a capacitance between the electrodes in absence of moisture.

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.
