Abstract Simultaneously endowing carbon nanofibers (CNFs) with flexibility, flame‐resistant properties, and high sonoelectric/mechanical‐electric energy conversion efficiency is quite challenging, restricting their wide application to smart fabrics. Herein, a carbon‐based nanofiber is prepared by electrospinning and subsequent carbonization with the formation of Bi 20 TiO 32 (BT), followed by in situ growth of hydrothermally produced Bi 2 S 3 (B) and MoS 2 (M) successively. Compared with pure CNF, the synthesized carbon/Bi 20 TiO 32 /MoS 2 /Bi 2 S 3 (CBT/M/B) fiber exhibited not only enhanced flexibility and antiflaming performance but also sensitive conversion ability of the mechanical power into electricity. Its enhanced flexibility is due to its electrospinning micro/nanostructure and interactions between grain boundaries. Importantly, the CBT/M/B fiber achieved the realization of relying on unique human motion to provide energy and convert it in a piezoelectric manner, thus exhibiting satisfactory antibacterial effects. This research provides valuable insights into smart wearable antibacterial fibers characterized by flexible, antiflaming, and mechanosensitive functions.
