Sheet-type organic active matrix amplifier system using V<inf>th</inf>-tunable, pseudo-CMOS circuits with floating-gate structure

We fabricated a flexible strain-sensing system consisting of a two-dimensional array of organic self-bias-feedback amplifier cells with signal-gain of 400 by integrating 2-V operational organic pseudo-CMOS inverters [1]. Switching voltages of pseudo-CMOS inverters with floating gates can be controlled by a randomly-accessible active matrix for reducing variations in switching voltages.
