Abstract
Methods and devices are described for operating an input device for an electronic system which includes a housing. The input device includes an input surface and a first substrate having a first plurality of sensor electrodes configured to sense input objects proximate the input surface, and a pair of force sensing electrodes on the bottom of the first substrate. The input device includes a second substrate having a planar spring plate including a perimeter region surrounding an interior region, the perimeter region including a leaf spring coupled to the housing, and a spacing layer configured to physically couple the interior region of the second substrate to the first substrate. A force applied to the input surface deflects the first substrate and the interior region relative to the perimeter region, changing a variable capacitance formed between the force sensing electrodes.
