1. An apparatus comprising:

  • a first layer having;

    a first set of detection electrodes that are spaced apart and electrically isolated from one another, each of the first set of detection electrodes substantially transparent to visible spectrum light; and

    a first set of interleavers, each of the first set of interleavers located between adjacent detection electrodes of the first set of detection electrodes, and each interleaver including;

    a first set of interleaving electrodes electrically coupled to a first detection electrode of the first set of detection electrodes, each interleaving electrode of the first set of interleaving electrodes protruded from and perpendicular to the first detection electrode, and each interleaving electrode of the first set of interleaving electrodes substantially transparent to visible spectrum light; and

    a second set of interleaving electrodes interleaving with the first set of interleaving electrodes, the second set of interleaving electrodes electrically coupled to a second detection electrode from the first set of detection electrodes, the second detection electrode spaced apart and electrically isolated from the first detection electrode, each interleaving electrode of the second set of interleaving electrodes protruded from and perpendicular to the second detection electrode, and each interleaving electrode of the first set of interleaving electrodes substantially transparent to visible spectrum light; and

    a second layer that is disposed over the first layer, the second layer having;

    a second set of detection electrodes spaced apart and electrically isolated from one another, each detection electrode of the second set of detection electrodes substantially transparent to visible spectrum light; and

    a second set of interleavers, each interleaver of the second set of interleavers located between adjacent detection electrodes of the second set of detection electrodes, and each interleaver of the second set of interleavers including;

    a third set of interleaving electrodes electrically coupled to a third detection electrode of the second set of detection electrodes, each interleaving electrode of the third set of interleaving electrodes substantially transparent to visible spectrum light; and

    a fourth set of interleaving electrodes electrically coupled to a fourth detection electrodes of the second set of detection electrodes, each interleaving electrode of the fourth set of interleaving electrodes substantially transparent to visible spectrum light.
