Abstract:
Devices and methods are provided that facilitate improved input device performance. The devices and methods utilize a set of sensor electrodes comprising at least one transmitter sensor electrode and at least one receiver sensor electrode that are capacitively coupled to form a transcapacitance for capacitively sensing input objects in a sensing region. A measure of the transcapacitance may be used to determine positional information for the input objects in the sensing region. In accordance with the various embodiments, the devices and methods additionally utilize at least one deflectable electrode, where the deflectable electrode is electrically floating. The deflectable electrode is configured to be deflectable toward the set of sensor electrodes, where the deflection causes a change in the transcapacitance.
