An enzymatic biofuel cell (BFC) is a type of fuel cell that enables harvesting electrical energy from biofluids such as juices and bloods without purification by using enzymes biocatalysts. Prof. Miyake presented many types of BFCs in previous JSAT conference. Examples include a flexible, stretchable and layered power source¹, a needle-type cell² for inserting raw grape and blood vein, a self-powered glucose indicator³. Here we present enzyme-CNT microfibers that generate a power from glucose. Such enzymatic power microfibers can be woven on T-shirts or patched on skins.
Our BFC was constructed using the NAD⁺-dependent glucose dehydrogenase (GDH)-based bioanode and the bilirubin oxidase (BOD)-based biocathode. We measured all performances with potentiostat. Our preliminary result is 230mW/cm² at 0.3V. In my presentation, I will discuss the detail about experimental results.
