Abstract

Embodiments of the present invention relate to graphene-based capacitive sensors. In one embodiment, a touch sensor comprises a non-porous insulating substrate having a first side and a second side. A first conductive material is at least partially in communication with the first side. A second conductive material is at least partially in communication with the first side. A third conductive material is at least partially in communication with the second side. The first conductive material and the second conductive material are in communication. The first conductive material forms a linearization pattern. The first conductive material includes a metal. The second conductive material and/or third conductive material comprise graphene sheets.
