Swiss researchers develop biodegradable battery powered by fungi

Swiss researchers have developed a new type of battery using fungi, specifically yeast and white rot fungus. This 3D-printed battery is biodegradable and generates electricity through a microbial fuel cell process, where fungi convert nutrients into energy. The battery features a yeast fungus that releases electrons and a white rot fungus that captures these electrons. The fungi feed on simple sugars added to the battery, which can be activated by adding water and nutrients. While the current output is limited, the battery could power small devices in remote areas. Researchers aim to enhance its power and longevity and explore other fungi for potential use in energy generation.
