Abstract
Embodiments described herein provide capacitance sensing devices and methods for forming such devices. The capacitance sensing devices include a substrate having a central and an outer portion. A plurality of substantially co-planar electrodes are on the central portion substrate. A first plurality of conductors are on the substrate. Each of the first plurality of conductors has a first end portion electrically connected to one of the plurality of electrodes and a second end portion on the outer portion of the substrate. An insulating material is coupled to the second end portions of the first plurality of conductors. A second plurality of conductors are coupled to the insulating material. Each of the second plurality of conductors is electrically connected to the second end portion of at least some of the first plurality of conductors and is insulated from the second end portion of the others of the first plurality of conductors.
