Low cost production and a simple manufacturing process are desired for organic field effect transistors, OFETs, even though this usually significantly lowers device performance. We report on applications and characterization of a high performance polymer field effect transistor that utilizes a hygroscopic insulator. The latter enables the device to be used as a sensor element to detect the presence of various solvents. We show a drastic change in conductivity and current modulation for some organic solvents. Furthermore, the use of the device in electric circuits is demonstrated by combining hygroscopic insulator field effect transistor (HIFET) devices in an inverter/amplifier circuit.
