Abstract
A thin film gas sensor device includes a substrate, a first electrode supported by the substrate, a second electrode supported by the substrate, and a gas-sensitive structure. The gas-sensitive structure is supported by the substrate and is electrically connected to the first and second electrodes. The gas sensitive structure includes a plurality of thin film layers of a first material vertically interleaved with a plurality of thin film layers of a second material. The first and second materials are mutually catalytic materials.
