摘　　要：触觉感知电子学将以电荷传输为主的有机光电器件与以离子信号为主的生物体桥接起来,被认为是新一代人工智能系统构建的重要研究领域.有机晶体管通过电场诱导或电化学离子掺杂调控半导体的导电能力,显示出独特的光电特性.基于其本征柔性、可溶液加工性和生物相容性等特点,有机晶体管被认为是发展柔性智能感知器件的良好载体.过去10年,随着功能材料设计合成和器件结构开发,基于有机晶体管的生物物理信号传感和突触感知研究受到广泛关注并取得快速发展.本文从具有物理信号转化、信号传递与处理功能的有机晶体管器件结构设计、工作原理和制备技术等方面,概述了触觉感知功能的有机晶体管研究进展,重点介绍了温度/压力感知功能有机晶体管的发展与应用现状,最后总结了新一代触觉感知有机晶体管的研究策略并展望了面临的挑战与机遇.Advancements in the research of organic bioelectronics,bridging organic optoelectronic devices primarily based on electronic transport with biological systems dominated by ion signals,are considered crucial areas for constructing the next generation of artificial intelligence systems.Organic transistors(OFET)exhibit unique optoelectronic properties by modulating the semiconductor’s conductivity through field-induced or electrochemical ion doping.Leveraging their flexibility,excellent solubility for processing,and significant biocompatibility,organic transistors have become excellent platforms for building organic intelligent sensing devices.Over the past decade,research on tactile perception organic transistors,focusing on the development of functional materials,device structures,and the integration of biological,physical signal sensing,and synaptic functionalities,has garnered widespread attention and rapid progress.In this paper,we provide an overview of the progress in tactile perception functionalization of organic transistors,covering aspects such as the design of device structures,working principles,and fabrication techniques that enable the conversion,transmission,and processing of physical signals.We emphasize the development and current applications in temperature/pressure sensing,synaptic,and neural learning,summarize the research strategies for the next generation of tactile perception organic transistors,along with the prospect for challenges and opportunities.
