Abstract:
A capacitive sensor a method of making a capacitive sensor are disclosed. The capacitive sensor includes: a plurality of rows of sensor electrodes included in a first layer; a plurality of columns of sensor electrodes included in a second layer, where the plurality of columns of sensor electrodes are arranged orthogonally to the plurality of rows of sensor electrodes to form a two-dimensional sensing array; and, a plurality of conductive elements included in a third layer disposed between the first and second layers, wherein, for each conductive element of the plurality of conductive elements, a first end of the conductive element is electrically connected to a sensor electrode in the plurality of rows of sensor electrodes and a second end of the conductive element is capacitively coupled to a sensor electrode in the plurality of columns of sensor electrodes to form a trans-capacitive sensing pixel of the two-dimensional sensing array.
