Abstract
An interface pressure sensor includes a fluid pressure sensor disposed in a volume defined by a shear wall. The volume is enclosed, and the fluid pressure sensor is encapsulated by, an infill material. The infill material defines a sensing surface that, when pressed, can impart a force that is detectable by the fluid pressure sensor.
Claims20
An interface pressure sensor system for an electronic device, the interface pressure sensor system comprising:
- a rigid module enclosure defining an interior volume;
- a barometric pressure sensor disposed within the interior volume;
- and
- an infill material disposed over the barometric pressure sensor and filling the interior volume to define an interface surface to receive force input from an object engaging the interface surface.
