a Schematic illustration of the in situ composite preparation through the in situ aerosol-assisted biosynthesis process. Carbon nanotubes (CNTs) are continuously settled and entangled by bacterial cellulose (BC) nanofibers. b The composite hydrogel with CNTs uniformly distributed in the 3D network of BC. c The obtained hydrogel strips are transformed into oriented fibers through wet drawing. d After wet twisting, the composite fibers are further densified and shaped. e After chemical treatment, muscle-inspired fibers are obtained. f The exquisite fascicle structure of skeletal muscle with muscle fibers embedded in the 3D network of the endomysium through proteins for bridging. g The muscle-inspired structure with CNTs embedded in the 3D network of BC through π–π interactions. h The tensile strength of the muscle-inspired fibers is higher than that of typical natural fibers. i The muscle-inspired fibers with a diameter of approximately 0.21 mm can stably be loaded with a weight of 0.5 kg. j The muscle-inspired fibers are used to hang a light bulb.
