Abstract

The invention discloses a preparation method of an electronic skin biofuel cell and a biofuel cell. The preparation method comprises: preparing an anode and a cathode substrate, on which a bottom electron conduction layer of a bioanode and a bottom electron conduction layer of a biocathode are prepared; The prepared anode material is printed on the anode site of the substrate, and the prepared cathode material is printed on the cathode site of the substrate, wherein, after the carbon nanotubes are activated, the mixture with naphthoquinone is ball milled in an argon atmosphere , and then mixed with acetic acid, glutaraldehyde, deionized water, chitosan and lactic acid oxidase to obtain a sol-like anode material; after activation of carbon nanotubes, ball milling in a nitrogen atmosphere, and then mixed with perfluororesin, deionized The ionic water is mixed and stirred to obtain a sol-like cathode material. The invention uses the bonding of graphene and carbon nanotubes to obtain a fast electron transport path, and then modifies the carbon nanotubes to obtain a flexible 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...
