Abstract: Combined force and proximity sensing is disclosed. One or more sensors can concurrently sense a force applied by an object on a device surface and a proximity of the object to the surface. In an example, a single sensor can sense both force and proximity via a resistance change and a capacitance change, respectively, at the sensor. In another example, multiple sensors can be used, where one sensor can sense force via either a resistance change or a capacitance change and another sensor can sense proximity via a capacitance change.
