Graphene, a new kind of material, has received widespread attention in the field of gas sensors. Organic thin film transistor (OTFT) gas sensor array is also a hot and difficult field in the international gas sensors, but the sensitive mechanism and regulation mechanism of this kind of sensors are not clear. This project intends to choose graphene as main sensitive materials, prepare the OTFT gas sensor array based on graphene combined with other sensitive materials, and research the influence of the sensitive material composition and structure of organic thin film transistor on the sensor’s performance. At the same time, we will research the integrated converting circuit of the OTFT gas sensor array, and in the end, obtain the integrated organic thin film transistor gas sensor array, which provides a key theoretical and technical basis for mixed gas detection. The sensor research will effectively promote domestic novel sensor technology research, and promote the development of electronic nose technology and the progress of the sensitive electronics and sensor technology.
