Abstract
Methods, systems and devices are described for use with an electronic system. The device includes a pliable component having an input surface and a first plurality of sensor electrodes; a support substrate spaced apart from the pliable component; a second plurality of sensor electrodes disposed on a second substrate; a spacing layer disposed between the pliable component and the support substrate, the spacing layer configured to locally deform in response to a force applied to the input surface; and a shield electrode layer disposed between the first plurality and the second plurality of sensor electrodes.
