Abstract: A device and method for operating a capacitive input device configured to sense input objects and their applied force in a sensing region, the device including a pliable component having an input surface and characterized by a bending stiffness, and first and second arrays of sensor electrodes. The input device further includes a third array of sensor electrodes and a spacing layer disposed between the third array. The pliable component is characterized by a compressive stiffness and configured to deform in response to a force applied to the input surface and to deflect the second array of sensor electrodes towards the third array of sensor electrodes, wherein the deformation of the input surface and the deflection of the second array of sensor electrodes is a function of the ratio of the bending stiffness of the pliable component and the compressive stiffness of the spacing layer.

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.

Abstract: Devices and methods are provided that facilitate improved input device performance. The devices and methods utilize a first substrate with proximity sensor electrodes and at least a first force sensor electrode disposed on the first substrate. A second substrate is physically coupled to the first substrate, where the second substrate comprises a spring feature and an electrode component. The electrode component at least partially overlaps the first force sensor electrode to define a variable capacitance between the first force sensor electrode and the electrode component. The spring feature is configured to facilitate deflection of the electrode component relative to the first force sensor electrode to change the variable capacitance. A measure of the variable capacitance may be calculated and used to determine force information regarding the force biasing the input device.
