According to the invention, a rapid electron transmission path is obtained by bonding graphene and carbon nanotubes, and then the carbon nanotubes are modified to obtain theflexible biofuel cell with high power density.

Description

technical field [0001] The invention relates to the field of biofuel cells, in particular to a method for preparing an electronic skin biofuel cell and the biofuel cell. Background technique [0002] Wearable electronics have attracted enormous academic and industrial interest due to their enormous biomedical, computing, entertainment, defense, and environment-related applications. In recent years, many examples of wearable devices embedded in textiles or mounted directly on human skin have been demonstrated. Ideally, wearable electronics should be thin, compact, flexible, and stretchable to enable conformal integration with human skin without inducing somatosensory responses. Thanks to new manufacturing techniques, material innovations, and advances in nanotechnology, researchers have managed to realize such wearable devices. However, a key challenge to achieve adoption in practical applications is the lack of corresponding thin wearable energy sources. Most previous eff...
