Abstract

A flexible hydrogen gas sensor based on pentacene organic thin-film transistor (OTFT) using palladium (Pd) source and drain (S/D) electrodes as the sensing medium is prepared on adhesive vacuum tape. The sensor exhibits a clear, rapid and concentration-dependent response upon hydrogen exposure without the need of heating. In addition, in order to demonstrate the flexibility of the sensor, measurements on a curved surface are performed. The sensor, when attached to the curved surface, shows normal transistor characteristics, which essentially remains the same after one hour of tensile stress.
