Researchers at Binghamton University in New York have created a “bacteria-powered battery on a single sheet of paper.” The project is aimed at creating batteries for disposable microelectronics that can run for weeks using a little bacteria-rich liquid.
“The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as a power source in remote, dangerous and resource-limited areas,” write the researchers.
The researchers used a piece of chromatography paper and a ribbon of silver nitrate under a layer of wax. The anode was made of “a conductive polymer on the other half of the paper” and a reservoir held bacteria-rich liquid. The cellular respiration powered the battery.
