Abstract
A capacitive type touch sensing device includes a first electrode array including a plurality of drive electrodes and a plurality of sense electrodes, and a second electrode array spaced apart from the first electrode array and including a plurality of discrete, electrically floating conductive regions. At least part of the second electrode array positionally overlaps with at least part of the first electrode array to define a separation distance therebetween, the separation distance varying with a force applied to a surface of the touch sensing device. Further, each conductive region is positioned relative to a respective drive electrode and sense electrode of the first electrode array so that a capacitance between certain pairs of drive and sense electrodes is more sensitive to a variation in the separation distance than a capacitance between other pairs of drive and sense electrodes.
