Abstract:
1. An input device comprising: a first plurality of sensor electrodes disposed in a first layer and configured to detect input objects at an input surface of the input device, the first plurality of sensor electrodes including a first subset of transmitter electrodes; a second plurality of sensor electrodes configured to toggle between a grounded state and a force receiver state, detect a force imparted to the input surface, and configured for capacitive coupling with the first subset of transmitter electrodes; a compressible dielectric configured to compress in response to force applied to the input surface; and a processing system communicatively coupled to the first plurality of sensor electrodes and the second plurality of sensor electrodes and configured to: wherein the capacitive coupling between the first subset of transmitter electrodes and the second plurality of sensor electrodes varies in response to the applied force.
