Abstract
In one embodiment, a touch sensor includes an insulating substrate comprising a first face. The touch sensor further includes a plurality of electrodes comprising one or more conductive materials formed on the insulating substrate. The touch sensor may also include a plurality of spacers extending outwardly from the first face of the first insulating substrate. Each spacer of the plurality of spacers may extend substantially the same distance from the first face of the insulating substrate. The plurality of spacers are operable to maintain a substantially consistent air gap between the plurality of electrodes and a cover panel when the cover panel is attached to the insulating substrate.
