Thin film gas sensors based on semiconducting ceramics have various advantages over the traditional bulk gas sensors, such as higher sensitivity, faster responsibility, and lower cost. Recent years the researches on this kind of sensors have got much attention in the research and development fields for gas sensors. It was believed that the film gas sensors based on semiconducting ceramics will be one of the development trends in gas sensors research in the near future. In this paper a review on the thin film gas sensors based on semiconducting ceramics in recent years was presented, the structures of the thin film gas sensor were outlined, the gas sensor materials and the manufacturing methods for the thin films were summed up, and some development features in the coming years were briefly analyzed.
