Miniature fuel cell made from folded filter paper runs on sugary drinks.
Researchers in China have found a way to integrate the ancient Japanese art of paper folding, origami, into a miniature biofuel cell that can generate energy from soft drinks.
Biofuel cells use enzymes, instead of precious metals, as catalysts to oxidise their fuel. Miniature versions have excited researchers because they are portable and have high efficiency. They could provide power for implants or electronic contact lenses or harvest energy from perspiration. However, designing these small biofuel cells is difficult due to complicated assembly and high costs.
