• • The PHE-JE sensor achieves high sensitivity and fast response across a wide range of human motions, including subtle physiological signals such as pulse, joint movement, and vocalization, owing to the deformation, breakage, and fracture of the PANI coating and JE microfibers.
• • The sensor demonstrates remarkable mechanical robustness, electrical stability, and long-term durability under repeated stretching and releasing cycles, indicating its suitability for continuous wearable monitoring.
• • The use of Juncus effusus fibers with a 3D triangular network provides a sustainable substrate, and the synergistic design with polyaniline and Ecoflex encapsulation enables rapid and low-cost fabrication of strain sensors.
• • The sensor exhibits high stability under various strain conditions, along with excellent flexibility and durability, making it a promising candidate for future wearable sensing applications.
