This paper introduces the research progress of OTFTs, and further analyzes the basic structure, working principle and electrical properties of OTFTs. The development history of sensors based on OTFTs are summarized. The advantages of the OTFT-based sensors are introduced with emphasis on their sensitivity and selectivity. Finally, the working mechanism of the OTFT-based sensors is analyzed.
