ABSTRACT:
Sensors are provided which are selective for a specific gas. The sensors include a substrate, electrodes, and a thin film metal oxide. Methods for choosing the metal oxide to be utilized in the sensor with selectivity for the specific gas are also provided, as are methods for determining the presence of a specific gas in a gaseous mixture.
