摘要：Methods, systems and devices are described for operating an electronic system which includes 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 detect a force imparted to the input surface and configured for capacitive coupling with the first subset of transmitter electrodes; and a compressible dielectric configured to compress in response to force applied to the input surface. The capacitive coupling between the transmitter electrodes and the second plurality of sensor electrodes is configured to vary in response to the applied force.

主权项：1. An input device for an electronic system, comprising: a pliable component having an input surface and a first plurality of sensor electrodes configured to sense input objects proximate the input surface; a support substrate spaced apart from the pliable component and having a second plurality of sensor electrodes configured to detect a force imparted to the input surface; and a spacing layer disposed between the pliable component and the support substrate, the spacing layer including a elastomeric sub-layer and a plurality of rigid dots.
