摘要

Photon-in-textile offers transformative potential for wearable sensing, yet persistent challenges in signal overlap, coupling, and quality degradation in dynamic, multivariate environments limit their efficacy. A new polarization-enhanced sensing technology, enabled by a spin fibre-textile capable of efficient decoupling between multivariable interference, is presented. We develop a discrete helix anchoring strategy that autonomously embeds circularly polarized materials within fibres during extrusion, yielding kilometer-scale spin-photon fibres—exceeding 1300 m in continuous length. More importantly, the resulting core-sheath beaded fibres exhibit a luminescence asymmetry factor of 0.41. The fibre-woven fabrics are then produced, allowing for dynamic, real-time signal acquisition by our developed polarization-enhanced sensing approach—that is, distinguishing spin light from surrounding optical fields—achieving signal segmentation and noise suppression at source with 92.63% signal entropy reduction in dynamic scenarios. This spin-photon-digital signal conversion system realizes a superior normalized signal-to-noise ratio of 1.0 (noiseless), thereby enabling multi-dimensional robotic control with 100% sensing accuracy under interference. Furthermore, we demonstrate the scalability and compatibility of this technology in polarization-based image processing, target recognition, and virtual reality. This work offers an innovative solution for robust, embedded intelligence in soft robotics and human-machine symbiosis.
