Abstract:
A touch sensor for a cursor control device includes a support layer, a first printed layer, and a second printed layer. The support layer includes a first surface and a second surface opposite from the first surface. The first printed layer includes a first conductive ink and is printed on the first surface of the support layer. The first printed layer includes a printed surface opposite from the support layer, and the printed surface of the first printed layer defines a touch area of the touch sensor. The second printed layer includes a second conductive ink and is printed on the printed surface of the first printed layer. The second printed layer is electrically connected to the first printed layer and forms a border around the touch area.
