    Abstract: A gas sensor (100) is disclosed. The gas sensor includes a gas sensing layer (118) including doped oxygen deficient tungsten oxide and a dopant selected from the group consisting of Re, Ni, Cr, V, W, and a combination thereof, at least one electrode (112) positioned within/adjacent to a layer of titanium (114), and a response modification layer (116). The at least one electrode (112) is in communication with the gas sensing layer (118) and the gas sensing layer (118) is capable of detecting at least one gas selected from the group consisting of NO, NO2, SOx, 02, H20 and NH3. The response modification layer comprises Ti, Ni, Cr, v, R and/or Re or a combination thereof. A method of fabricating the gas sensor is also disclosed. The gas sensor may be used in a variety of applications, one embodiment disclosed is detecting NOx in exhaust emissions from automobiles.
