摘要
视觉感知是人与自然界最为重要的交互方式之一,提供了人体80%以上的外部环境信息.基于此,视觉仿生成为智能感知材料与器件研究中的前沿方向.过去30年,基于有机半导体的光电传感与感知器件历经多代发展,创新了光刺激(强度、色度等)的高灵敏度和选择性传感检测,并拓展了复杂的类生物视觉信号识别、学习与处理功能,已经成为新兴的跨学科领域.本文从单元光敏感的有机光电器件和多功能集成,介绍面向视觉感知功能化的有机光探测器、有机光电突触和有机适应型器件的构建策略和研究进展,并从柔性矩阵化和功能集成的视觉信号成像、学习与编码概述了新一代有机智能感知电子器件的仿生应用探索.
Visual perception is one of the most crucial ways in which humans interact with the natural world,providing over 80%of external environmental information to the human body.Based on this,visual bionics has emerged as a cutting-edge direction in the research of intelligent sensing materials and devices.Over the past three decades,the development of photoelectric sensing and perception devices based on organic semiconductors has undergone multiple generations,innovating high sensitivity and selectivity sensing detection of optical stimuli(intensity,color,etc.).It has expanded into recognizing,learning,and processing complex bio-inspired visual signals,establishing itself as an emerging interdisciplinary field.This review focuses on unit photosensitive organic optoelectronic devices and multifunctional integration,introducing the construction strategies and research progress of organic photodetectors,organic optoelectronic synapses,and organic adaptive devices for designed for visual perception.Furthermore,this review outlines the exploration of the biomimetic applications of the new generation of organic intelligent sensing electronic devices,emphasizing flexible matrixing and functional integration for visual signal imaging,learning,and encoding.
