1. A method of making an article, comprising:

  • applying carbon nanotube growth catalyst on to a surface of a substrate;

    subjecting the substrate to a chemical vapor deposition of a carbon-containing gas to grow a non-woven fabric of carbon nanotubes, wherein the nanotubes of the fabric are substantially parallel to said surface of the substrate;

    selectively removing portions of the non-woven fabric according to a defined pattern; and

    providing first and second electrodes in contact with respective first and second portions of the patterned non-woven fabric to create the article, wherein the patterned non-woven fabric forms a conductive trace between the first and second electrodes.
