Abstract
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.
