(a) Schematic configuration of organic electrochemical transistors (OECTs) embedded in a flexible substrate polyimide. (b) Digital photograph of the encapsulated flexible device. The SEM image shows a magnified individual transistor. The scale bar is 10 μm. (c) The output characteristics of the flexible OECTs obtained by using a Ag/AgCl pellet as a gate electrode at Vgs varying from −0.5 V to 1.0 V with a step width of 0.1 V. (d) The extracted transfer characteristics from (c) at Vds = −0.5 V.
