Abstract

A low-voltage hydrogen sensor based on pentacene organic thin-film transistor (OTFT) with Pd source and drain (S/D) electrodes is fabricated on vacuum tape with a maximum temperature of 200 °C. The flexible sensor shows a clear decrease in drain current when exposed to H2in air at room temperature. Owing to reduced carrier mobility and increased S/D series resistance (both induced by the expansion of the Pd electrodes after absorbing hydrogen), rapid and concentration-dependent response of the OTFT is realized at various H2concentrations ranging from 200 ppm to 15,000 ppm.
