The rapid development of flexible and easy-tointegrate wearable electronics places greater demands on the design of fibrous triboelectric materials. However, mechanical mismatch between the dielectric and electrode interfaces remains one of the challenges for achieving device durability and high outputs. A weavable and stretchable fibrous triboelectric material (PDMS/PPy/AgNPs/JE) was developed based on a porous Juncus effusus template employing in situ growth and injection molding. The topological interlocking structure between the dielectric layer (PDMS) and electrode (PPy/AgNPs/JE) enables PDMS/PPy/AgNPs/JE to withstand 142% strain while maintaining stable performance after 10,000 working cycles. PDMS/PPy/AgNPs/JE exhibits excellent output voltage (～ 46 V) due to the Schottky junction at the interface between PPy and AgNPs. It suggests excellent application advantages in self-powered pressure sensing and array identification. This work provides a new idea for the material construction of stable and high-output wearable sensors.
