Researchers at Empa’s Cellulose and Wood Materials laboratory have unveiled a groundbreaking 3D printed biodegradable fungal battery, using sugar to generate power for small devices like sensors. This device functions more accurately as a microbial fuel cell, utilizing two mushroom types—yeast fungi on the anode releasing electrons and white rot fungi on the cathode facilitating electron capture. The battery is not only designed to be environmentally friendly by comprising biodegradable materials like fungi and cellulose but also functions temporarily, lasting several days before self-decomposition, thus aligning with eco-conscious technological advancement.
Researchers at Empa have developed a 3D printed biodegradable fungal 'battery' that uses sugar for energy, effectively functioning as a microbial fuel cell.
This innovative battery is made from two types of fungi and can power small devices for several days before digesting itself, promoting sustainability.
