ABSTRACT:
Disclosed is a method of fabricating a carbon monoxide detector and a carbon monoxide detector fabricated using the same. Particularly disclosed is a method of fabricating a carbon monoxide detector, which can operate at room temperature and process high detecting selection, and the detector fabricated using the same. The method comprises: providing a substrate having an upper surface; forming two electrode sets on the upper surface of the substrate, and the two electrode sets combined to provide an interdigitated array electrode; forming a tin dioxide layer, which covers the portion of the two electrode sets and the portion of the upper surface; and forming an organic polymer layer on the surface of the tin dioxide layer. The carbon monoxide detector comprises: a substrate having an upper surface; two electrode sets, which are located on the upper surface of the substrate; a tin dioxide layer, which covers the portion of the two electrode sets and the portion of the upper surface; and an organic polymer layer, which is located on the surface of the tin dioxide layer.
