Abstract:
1. A capacitive imaging sensor, comprising: a first array of first sensor electrodes disposed on a surface of a substrate, wherein each of the first sensor electrodes comprise a first electrode region, and each of the first electrode regions are aligned in a first direction that is parallel to the surface; a first array of second sensor electrodes disposed on the surface of the substrate, wherein each of the second sensor electrodes comprise a second electrode region, and each of the first electrode regions in the first array of first sensor electrodes are positioned to directly capacitively couple to at least a portion of a second sensor electrode in the first array of second sensor electrodes; a second array of first sensor electrodes disposed on the surface of the substrate, wherein each of the first electrode regions of the first sensor electrodes in the second array are aligned in the first direction; and a second array of second sensor electrodes disposed on the surface of the substrate, wherein each of the first electrode regions in the second array of first sensor electrodes are positioned to directly capacitively couple to at least a portion of a second sensor electrode in the second array of second sensor electrodes, wherein the second array of first sensor electrodes are positioned a distance in a second direction from the first array of first sensor electrodes, and the second direction is not parallel to the first direction, and wherein the first array of first sensor electrodes and the second array of first sensor electrodes are disposed on the surface of the substrate between the first array of second sensor electrodes and the second array of second sensor electrodes, and at least one second sensor electrode in the first array of second sensor electrodes is electrically coupled to at least one second sensor electrode in the second array of second sensor electrodes.
