摘要
Constructing an artificial intelligence interactive system is still challenging due to the lack of an integrated artificial sensing and processing system with high performance.In this work,an artificial tactile perception system with integrated sensing,storage,and computing functions is designed based on silk fibroin composite memristors and piezoresistive pressure sensors.The sensors based on polydimethylsiloxane/silver nanowires can sense the external pressure stimulation with fast response speed.In addition,the composite memristor based on silk fibroin possesses good cyclic stability and synaptic plasticity simulation and acts as an artificial synapse to process tactile information.As a result,the integrated tactile perception system realizes the perception,storage,and processing of pressure information,demonstrating the possibility to simulate the biological tactile perception nervous system.This type of system may promote potential applications in artificial intelligence,such as autonomous driving,wearable,flexible electronic devices,and bionic robots.
构筑人工智能交互系统依然存在挑战,其原因在于缺少高性能的感知-计算集成系统.本研究基于丝素蛋白复合忆阻器与压阻式传感器设计了集感-存-算功能于一体的人工触觉感知系统.传感器由聚二甲基硅氧烷/银纳米线构成,可快速响应外界压力刺激.丝素蛋白复合忆阻器具有优异的循环稳定性及突触可塑性模拟功能,可作为人工突触处理触觉信息.本文集成的触觉感知系统可实现对压力信号的感知、存储及加工,证实了其模拟生物体触觉神经系统的可能,有望在自动驾驶、可穿戴柔性电子、仿生机器人等人工智能领域广泛应用.
