Abstract
In certain embodiments, an apparatus includes a first substrate with sense electrodes of a touch sensor disposed on it and a second substrate with drive electrodes of the touch sensor disposed on it. One or more of the following is true: the sense electrodes of the first substrate are made of a first conductive mesh of conductive material such that the sense electrodes include the first conductive mesh; and the drive electrodes of the second substrate are made of a second conductive mesh of conductive material such that the drive electrodes include the second conductive mesh. The apparatus also includes an insulating layer between the sense electrodes of the first substrate and the drive electrodes of the second substrate.
