From: Flexible suspended gate organic thin-film transistors for ultra-sensitive pressure detection

Schematic illustration of (a) the experimental set-up, (b) a SGOTFT-based array with magnified device geometry and (c) (d) pressure-sensing process. (e) Photograph of a SGOTFT; scale bar, 1 mm. (f) Electrical equivalent circuit of the SGOTFT. Output curves of the SGOTFT taken at a pressure of (g) 0 and (h) 1,000 Pa.
