Emulation of human sensory and motor functions becomes a core technology in bioinspired electronics for next-generation electronic prosthetics and neurologically inspired robotics. An electronic synapse functionalized with an artificial sensory receptor and an artificial motor unit can be a fundamental element of bioinspired soft electronics. Here, we report an organic optoelectronic sensorimotor synapse that uses an organic optoelectronic synapse and a neuromuscular system based on a stretchable organic nanowire synaptic transistor (s-ONWST). The voltage pulses of a self-powered photodetector triggered by optical signals drive the s-ONWST, and resultant informative synaptic outputs are used not only for optical wireless communication of human-machine interfaces but also for light-interactive actuation of an artificial muscle actuator in the same way that a biological muscle fiber contracts. Our organic optoelectronic sensorimotor synapse suggests a promising strategy toward developing bioinspired soft electronics, neurologically inspired robotics, and electronic prostheses.
模仿人类的感觉和运动功能成为仿生电子学的核心技术，用于下一代电子假肢和神经启发型机器人。功能化的电子突触，结合人工感觉受体和人工运动单元，可以成为仿生软电子学的基本元件。在这里，我们报告了一种有机光电感觉运动突触，它使用有机光电突触和基于可拉伸有机纳米线突触晶体管（s-ONWST）的神经肌肉系统。光信号触发的自供电光电探测器的电压脉冲驱动 s-ONWST，而产生的信息性突触输出不仅可用于人机接口的光学无线通信，还可用于以与生物肌肉纤维收缩相同的方式，实现人工肌肉执行器的光交互式致动。我们的有机光电感觉运动突触为开发仿生软电子学、神经启发型机器人和电子假肢提供了一种很有前途的策略。
