Abstract: A force-sensitive input device and related method and processing system are disclosed. The input device comprises a first substrate mounted to a housing and defining a touch surface extending along first and second dimensions. The input device further comprises a second substrate disposed within the housing on a side of the first substrate opposite the touch surface. The second substrate comprises a first sensor electrode disposed along a periphery of the touch surface in the first and second dimensions, and a second sensor electrode disposed along the periphery of the touch surface and at least partly circumscribing the first sensor electrode in the first and second dimensions. The input device further comprises a processing system configured to perform capacitive sensing using the first and second sensor electrodes to determine a deflection of the first substrate relative to the housing in response to force applied to the touch surface.

Abstract: An input device may include various sensor electrodes that detect positional information of an input object in a sensing region of the input device. The input device may include a first sensor electrode that detects a first change in a first variable capacitance in response to a deflection of a conductive layer by the input object. The input device may include a second sensor electrode that detects a second change in a second variable capacitance in response to the deflection of the conductive layer by the input object. The first change in the first variable capacitance and the second change in the second variable capacitance may determine an acquired force image of the input force. An adjusted force image may be determined from the acquired force image using the positional information.
