Scientists in Switzerland have invented a biodegradable battery powered by fungi, the key material being the building block of mushrooms. The fungal battery can produce enough electricity to power sensors for several days, offering a sustainable alternative to traditional batteries. The innovative technology involves a 3D-printed design combining two fungal species, a yeast fungus on the anode side and a white rot fungus on the cathode side, to generate and capture electrons. These living batteries are environmentally friendly as they self-digest by consuming cellulose-based ink once they have served their purpose. While the project faces challenges working with living materials, researchers are optimistic about the potential for further development to increase the power and longevity of fungal batteries.
