智能交互式电子设备可以动态地响应并可视化环境刺激。受自然界生物快速变色的启发，提出了一种具有高拉伸性和可调颜色的交互式电子光纤传感器。它是基于一个巧妙的多鞘层设计的压阻电子纤维与机械致变色光子晶体微管耦合。通过重构导电路径和调节光子鞘层的晶格间距，它具有同时感测和可视化其变形的独特能力。特别是，它表现出动态的颜色切换跨越整个可见光区（从红色到蓝色），快速的光/电响应（约80毫秒），和一个大的工作范围（0-200%），允许其作为一个用户交互式传感器的应用程序，用于动态监测大关节运动和肌肉微振动的人体在真实的时间。这项研究提供了一个通用的平台，新兴的交互设备，这是有前途的应用在可穿戴电子产品，人机交互，智能机器人。
Smart interactive electronic devices can dynamically respond to and visualize environmental stimuli. Inspired by the rapid color changes of natural creatures, an interactive electronic fiber sensor with high stretchability and tunable coloration is presented. It is based on an ingenious multi-sheath design on a piezoresistive electronic fiber coupled with a mechanochromic photonic crystal microtubule. It has the unique capabilities of sensing and visualizing its deformation simultaneously, by reconstructing conductive paths and regulating the lattice spacing of the photonic sheath. In particular, it exhibits dynamic color switching spanning the full visible region (from red to blue), fast optical/electrical response (approximate to 80 ms), and a large working range (0-200%), allowing its application as a user-interactive sensor for dynamically monitoring large joint movements and muscle microvibrations of the human body in real time. This investigation provides a general platform for emerging interactive devices, which are promising for applications in wearable electronics, human-machine interactions, and intelligent robots.
