Until now, optical fibers that simultaneously exhibit mechanical robustness, signal decoupling, and environmental stability remain scarce, and system\u2010level integration is even rarer. Inspired by the distributed sensory arrangement of jellyfish tentacles, we propose a photonic skin composed of coaxially structured hydrogel optical fibers, in which pressure and temperature signals are routed through independent photonic and ionic channels for interference\u2010free multimodal sensing. The stretchable, highly reproducible, refractive\u2010index\u2010matched core\u2010cladding photonic fiber was constructed by continuous coaxial spinning with in situ photopolymerization. It resolves the long\u2010standing trade\u2010off between mechanical stretchability, low\u2010loss optical guiding, and temperature\/humidity robustness in hydrogel fibers. The assembled sensing skin achieves high pressure and temperature sensitivity with a sub\u201010\u2010ms response, surpassing existing benchmarks. It integrates with a lightweight, flexible printed circuit and multimodal tactile fusion machine\u2010learning architecture to form a wearable system, enabling wireless control, adaptive gesture recognition (99.21% accuracy), and multimodal object classification (99.22% accuracy). This work presents a fully integrated photonic skin platform bridging material\u2010level signal decoupling and system\u2010level multimodal perception for intelligent tactile interfaces in complex environments.<\/jats:p>","DOI":"10.1002\/adma.72869","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T17:26:31Z","timestamp":1773941191000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Coaxial
