http://www.freepatentsonline.com/8110883.html

This latest patent from the nanotube electronics pioneer Nantero teaches new applications of their nanotube fabrics in optical sensors. Claim 1 reads:

1. An electromagnetic radiation detector comprising:

a substrate;

a nanotube fabric disposed on the substrate, the nanotube fabric comprising a non-woven network of nanotubes and first and second conductive terminals, each in electrical communication with the nanotube fabric, the first and second conductive terminals disposed in space relation to one another;

wherein the nanotube fabric is tuned and derivitized to be sensitive to a predetermined range of electromagnetic radiation such exposure to the electromagnetic radiation generates a temperature change in the fabric that induces a change in the nanotube fabric resistance between the first and second conductive terminals.
