摘要：

A strain sensor presenting a voltage signal has been studied, as comprised of an organic thin-film transistor (OTFT) and an organic Schottky diode which are connected in series to sensitively measure elastic tensile strain (up to similar to 0.64%, bending radius of similar to 4 mm). We chose organic heptazole TFT as a sensor component and large area heptazole Schottky diode as a strain-insensitive load incorporated into this strain sensor gauge circuit, because our heptazole TFTs have shown anisotropic response to the elastic tensile strain. Our organic strain sensor exhibits a decent amount of gauge factor (GF > 1.51) performance in both static and dynamic ways. (C) 2016 Elsevier B.V. All rights reserved.
