Leveraging high-performance polyurethane elastomer, ultra-thin flexible electrodes fabricated, can achieve long-term monitoring physiological signals human body.

Abstract Smart fabrics with health protection, motion monitoring, and perception capabilities effectively managed optimized human health, significantly promoting the development of smart health. However, it remains challenging to achieve multifunctional mechanical robustness required for use in multiple scenarios without destroying characteristics softness air permeability. Here, a cross‐scale regulation strategy is presented based on chemical coupling‐physical twisting develop multiscale twisted core‐shell structure yarn. Benefiting from strong interfacial interactions coaxial wrapping structure, multi‐component functional particles are highly stably integrated into yarn while achieving ultra‐high strength (≈0.662 GPa). The resulting fabric exhibits good impact resistance (attenuate > 40% force), superior permeability (387.37 mm s −1 ), excellent eletromagnetic interference (EMI) shielding (36.1 dB), IR thermal camouflage, high triboelectric output ( V oc ≈39.1 V), ability sensitively perceive environment safety monitor real‐time. This study addresses long‐lasting challenge balancing functionality comfort offers new perspective developing next‐generation advanced wearable protective fabrics.
