EMPA develops biodegradable fungi battery

A team from the Swiss Federal Laboratories for Materials Science and Technology (Empa) has developed a 3D-printed battery. Fungi are used as anode and cathode with one releasing electrons during metabolism and the other able to absorb them.

Researchers in Switzerland are developing a biodegradable battery made from mushrooms. At Empa, a 3D printer has combined two types of mushrooms to create a small living cell that generates electricity.

The academics responsible report a possible application for non-toxic power supply in simple measuring devices such as the temperature sensors used in agriculture or environmental research. After supplying temperature sensors with power for a few days, the organic batteries would decompose.
