This paper describes the working principles of OTFT, including OFET and OECT, and compares the differences between them. It also discusses the potential for OTFT in biomarker sensing applications and improving patient outcomes.
Due to their advantages of low cost, flexibility, ease of manufacture and biocompatibility, organic thin film transistor (OTFT) hold great commercial potential. Specifically, there are two types of OTFT, OFET and OECT, which are widely used in the field of flexible biological sensors and have great ability for glucose and DNA detection of diabetes. In this paper, we describe the working principles of OFET and OECT, and compare the differences between them. Some examples are given and clarified, including the materials, fabrication and chemical reactions. There is still a lot of space to be explored in OTFT for other biomarker sensing applications. With the emergence of new materials and fabrication techniques, OTFT-based biosensor would be more widely used in diagnostic equipment to improve patient outcomes.
