Recent years have witnessed the explosive development of flexible strain sensors. Nanomaterials been widely utilized to fabricate sensors, because their high flexibility and electrical conductivity. However, fabrication processes for nanomaterials subsequent sensors are generally complicated manufactured at cost. In this work, we developed a facile dry-Meyer-rod-coating process sheath-core-structured single-fiber using ultrafine graphite flakes as sheath silk fibers core by virtue flexibility, production, low The fabricated sensor exhibits sensitivity with gauge factor 14.5 within wide workable range up 15%, outstanding stability (up 3000 cycles). single-fiber-based could be attached human body detect joint motions or easily integrated into multidirectional monitoring multiaxial strain, showing great potential applications wearable
