Light sensors and opto-logic gates based on organic electrochemical transistors

Abstract

In this study, we combine a photochemical cell with a transistor, forming a novel optical-to-electronic interface using OECTs with a light-sensitive gate, which can be used for photonic, optogenetic and other applications where conversion from an optical to electronic signal is key.

Designing Inverters Based on Screen Printed Organic Electrochemical Transistors Targeting Low‐Voltage and High‐Frequency Operation

“…Organic electronics comprises different classes of electronics such as printed electronics, [2][3][4] wearable electronics, [5,6] bioelectronics, [7][8][9] stretchable electronics, [10] which enable electronic applications toward large-area [4] and unconventional form factors of electronic devices [11][12][13][14][15] manufactured on a variety of substrates and carriers. [16,17] Organic electrochemical transistors (OECTs), [16,[18][19][20][21][22][23][24][25][26][27] is currently one of the most studied organic electronic devices and is explored in various applications, such as in fully printed logic circuits, [16,26] active matrix addressed displays, [17] display driver circuits, [19] sensors, [22,23,[28][29][30][31][32][33] neuromorphics, [24] just to name a few. OECTs can be manufactured via costeffective protocols using different printing techniques, such as screen printing, [19,21] 3D printing, [30] inkjet printin...…”

High‐Transconductance Stretchable Transistors Achieved by Controlled Gold Microcrack Morphology

“…Unlike conventional field effect transistors (FETs), OECTs consist of an active layer with mixed electronic and ionic transport, enabling remarkably high transconductance ( g m ) for high amplification of signals . For example, OECT‐based devices for electrophysiological recording with high signal integrity, highly sensitive biosensors, neuromorphic applications, display drivers, and optical logic gates have been reported. However, practical applications of OECTs critically rely on the development of devices with a high transconductance at high strain (≈100%) to accommodate for the dynamic range of motions and shapes of the human body .…”

Regulating Light‐Sensitive Gate of Organic Photoelectrochemical Transistor toward Sensitive Biodetection at Zero Gate Bias

“…[23][24][25] Currently, for the important signal amplification in PEC bioanalysis, major efforts have been devoted to various biological routes, such as enzymatic catalysis and nucleic acid-based amplification technologies. [26,27] The rise of light-sensitive G [28][29][30] elegantly bridges the gap between OECT and PEC bioanalysis, leading to synergized, light-controlled, and possible V G -free organic photoelectrochemical transistor (OPECT) devices with better detection performance. The introduction of immense light-matter interplay in such devices can potentially make them structurally simplified, remote-controlled, and even self-powered with many other unknown characteristics.…”
