摘要

Wearable sensors have attracted significant attention due to their superior sensitivity, safety, and adaptability compared with conventional detection technologies. However, developing sustainable sensing materials that combine excellent performance with environmental friendliness remains a significant challenge. In this study, Juncus effusus (JE), a natural fiber featuring a unique internal three-dimensional (3D) network structure, was employed as the substrate. Conductive polyaniline was loaded onto the JE structure to impart electrical conductivity, and Ecoflex encapsulation provided high elasticity. Based on this approach, a JE-based resistive flexible sensor (PHE-JE) was successfully fabricated. The PHE-JE sensor exhibits high stability under various strain conditions, along with excellent flexibility and durability. Moreover, benefiting from its complex 3D structure and synergistic material interactions, the PHE-JE sensor enables accurate detection of diverse motion types, showing promising potential for future wearable sensing applications.
