Abstract:
An input device having a sensing region overlapping an input surface includes a first substrate, a second substrate physically coupled to the first substrate, and a sensor electrode disposed on the first substrate and configured to detect input objects in the sensing region. A first force sensor includes a first electrode disposed on the first substrate and a first conductive portion of the second substrate capacitively coupled with the first electrode. The first conductive portion is configured to move relative to the first electrode such that a first variable capacitance of the first force sensor changes in response to force applied to the input surface in a first direction parallel to the touch surface.
