Abstract: 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.

TL;DR: A distributed and shared amplifier (DSA) architecture is proposed, which enables an in-situ amplification of the myoelectric signal with a fourfold increase in EMG electrode density and a post-fabrication select-and-connect method is proposed to cope with the large mismatch of organic transistors.

Ultralow-power organic complementary circuits
TL;DR: This work demonstrates an organic circuit with very low power consumption that uses a self-assembled monolayer gate dielectric and two different air-stable molecular semiconductors (pentacene and hexadecafluorocopperphthalocyanine, F16CuPc) to implement transistors, circuits, displays and sensors on arbitrary substrates.
