A waterproofed environmental sensing device with water detection provisions includes an environmental sensor to sense one or more environmental properties. The device further includes an electronic integrated circuit implemented on a substrate and coupled to the environmental sensor via a wire bonding. An air-permeable cap structure is formed over the environmental sensor, and a protective layer is formed over the wire bonding to protect the wire bonding against damage.

Water proofing and water detection schemes for MEMS-based environmental sensing devices

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.

Multicavity pressure sensor

A pressure sensing module for an electronic device includes a substrate and a module housing coupled to the substrate. The module housing defines a first chamber and a second chamber. The second chamber is separate from the first chamber. The first chamber is configured to connect to an environment around an electronic device. The second chamber is configured to connect to an internal volume of the housing of the electronic device. A first pressure sensing element is electrically coupled to the substrate and disposed in the first chamber and is operative to detect an external pressure around the electronic device. A second pressure sensing element is electrically coupled to the substrate and disposed in the second chamber and is operative to detect an internal pressure within the electronic device housing.

Dual pressure sensing module with a shared electrical substrate

An electronic device can include a force and touch sensing system. In one embodiment, an input force sensor device of an electronic device is disclosed.
