Abstract: A device and method for operating a capacitive touch screen 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.
