The gas sensing film includes a polycrystalline tungsten trioxide film thermally connected to the heat source and a plurality of islands of gold on a surface of the polycrystalline tungsten trioxide film. The surface of the polycrystalline tungsten trioxide film is exposed between the islands of gold to allow the polycrystalline tungsten trioxide film to sense gas. A first electrode that electrically connected to the polycrystalline tungsten trioxide film and a second electrode is electrically connected to the polycrystalline tungsten trioxide film. The resistance of the polycrystalline tungsten trioxide film between the first electrode and the second electrode changes when the polycrystalline tungsten trioxide film is exposed to a particular type of gas."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Robust sensing film for fire gases","description":"A gas sensor that includes a heat source and a gas sensing film.
