Recently, Professor Huang Jia and their team from the School of Material Science and Engineering at Tongji University have achieved a significant breakthrough in the realm of organic transistor sensing devices. Their groundbreaking research has been featured in the esteemed journal Nature Communications, with the paper titled "Near-infrared Organic Photoelectrochemical Synaptic Transistors Fabricated via Wafer-Scale Photolithography for Neuromorphic Visual Systems."

Faced with challenges such as high programming nonlinearity, a limited number of memory states, restricted response wavelength ranges, and difficulties in fabricating wafer-scale arrays for organic optoelectronic synaptic devices, the research team rose to the occasion. They successfully fabricated wafer-scale arrays of near-infrared organic photoelectrochemical transistors. This was accomplished through innovative heterojunction and ion doping designs, coupled with refined photolithography techniques. The resulting array devices boasted exceptional uniformity and outstanding near-infrared light sensing capabilities, achieving ultra-low nonlinear programming characteristics across a broad conductivity range.

In addition to these achievements, the research team constructed a near-infrared visual system. This system is capable of recognizing, memorizing, and visualizing near-infrared patterns. Moreover, they developed a convolutional computing system that successfully identified noisy handwritten digits. These accomplishments underscore the vast application potential of this research in the field of neuromorphic visual perception systems.
