Fiber electronics with mechanosensory functionality are highly desirable in healthcare, human–machine interfaces, and robotics. Most efforts are committed to optimize the electronically readable interface of fiber mechanoreceptor, while the user interface based on naked-eye readable output is rarely explored. Here, a scalable fiber electronics that can simultaneously visualize and digitize the mechanical stimulus without external power supply, named self-powered optoelectronic synergistic fiber sensors (SOEFSs), are reported. By coupling of space and surface charge polarization, a new mechanoluminescent (ML)-triboelectric synergistic effect is realized. It contributes to remarkable enhancement of both electrical (by 100%) and optical output (by 30%), as well as novel temporal–spatial resolution mode for motion capturing. Based on entirely new thermoplastic ML material system and spinning process, industrial-level continuously manufacture and recycling processes of SOEFS are realized. Furthermore, SOEFSs’ application in human–machine interface, virtual reality, and underwater sensing, rescue, and information interaction is demonstrated.

具有视觉-数字协同作用的自供电交互式光纤电子设备

具有机械传感功能的光纤电子产品在医疗保健、人机界面和机器人技术中非常受欢迎。大多数努力致力于优化纤维机械感受器的电子可读界面，而很少探索基于肉眼可读输出的用户界面。在这里，报告了一种可扩展的光纤电子设备，它可以在没有外部电源的情况下同时可视化和数字化机械刺激，称为自供电光电协同光纤传感器 (SOEFS)。通过空间和表面电荷极化的耦合，实现了一种新的机械发光（ML）-摩擦电协同效应。它有助于显着增强电输出（100%）和光输出（30%），以及用于运动捕捉的新型时空分辨率模式。基于全新的热塑性ML材料体系和纺丝工艺，实现SOEFS的工业级连续制造和回收工艺。此外，还展示了 SOEFS 在人机界面、虚拟现实以及水下传感、救援和信息交互方面的应用。
