Abstract
The embodiments described herein provide devices and methods that facilitate improved sensor devices. In one embodiment, a capacitive input device is provided that includes a processing system, a plurality of sensing electrodes configured to sense objects in a sensing region, a conductor, and a shield layer comprising at least one shield electrode, where the at least one shield electrode is disposed between the plurality of sensing electrodes and the conductor. The processing system is configured to operate in a first mode and a second mode. When operating in the first mode the processing system is configured to determine position information for objects in the sensing region using the plurality of sensing electrodes. When operating in a second mode the processing system is configured to electrically float the at least one shield electrode and to determine force information for objects in the sensing region using the plurality of sensing electrodes.
