▎ 摘　　要

NOVELTY - All-fiber-based self-powered sensor has a fiber-based lead connected between a fiber-based self-generating unit, a fiber-based sensing unit and a fiber-based lead. The fiber-based self-generating unit is provided with a fiber-based P-type power generation region, a fiber-based N-type power generation region and an electrode. The fiber-based P-type power generation region is provided with a fiber or yarn base material. A P-type thermoelectric material is coated on a surface of the fiber or yarn base material. The fiber-based sensing unit is provided with a fiber-based physical sensing unit or a fiber-based biochemical sensing unit. USE - All-fiber-based self-powered sensor for use in fields of national defense and military project, smart textiles and wearable electronic device. ADVANTAGE - The sensor has broad application prospects in the fields of national defense, smart textiles, and wearable electronic devices.
