Flexible, breathable and widely implementable triboelectric nanogenerator is highly demanded for wearable electronics to satisfy the technical requirements of the Internet of Things (IoT). The fabric-based wearable electronic devices have conspicuous advantages, however, how to optimize their electrical performance and comfortable characteristics is a great challenge. Here, we reported a waterproof, breathable and wearable electronics by fabricating nanofiber-based triboelectric nanogenerator (NF-TENG). The NF-TENG was consisted of the electrospun PA66/MWCNTs (multi-walled carbon nanotubes) nanofibers film with the nano-net structure used as the tribo-positive layer and the electrospun PVDF nanofibers film used as the tribo-negative layer, respectively. Owing to the coupling effect between the nano-network structure and porous structure, the effective contact area is enhanced effectively. A 20 mm x 20 mm NF-TENG demonstrates a peak voltage, current and a maximum power density up to 142 V, 15.5 mu A and 1.30 W/m2, respectively. The NF-TENG can be worth spread application to resolve power source for some wearable electronics. Also, the as-obtained NF-TENG has high gaspermeability of 11.5 mm s-1 benefiting from the hierarchical networks, and thus exhibits good washable characteristics. These results indicate that the NF-TENG is promising for providing a new vision in the area of selfpowered wearable technology.
