Fiber-based strain sensors have become a vital part for wearable electronics owing to their lightweight, flexibility, and easy processing. A poly(styrene-butadiene-styrene) (SBS)/MXene composite and coaxial fiber based strain sensors were produced through a continuous, facile, and scalable wet-spinning approach, which exhibited both high stretchability and sensitivity. Electromechanical properties displayed that SBS/MXene composite fibers showed extremely high sensitivity (1.63 x 104), low strain detection (0.5%), and outstanding durability and reliability, which laid a foundation for detectin...
