Researchers have created a bacteria-powered battery

Researchers at Binghamton University, state of New York, have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics, its use can revolutionize the use of bio-batteries. On one half of a piece of chromatography paper the researchers placed a ribbon of silver nitrate underneath a thin layer of wax to create a cathode. The pair then made a reservoir out of a conductive polymer on the other half of the paper, which acted as the anode.
Once properly folded and a few drops of bacteria-filled liquid are added, the microbes’ cellular respiration powers the battery. Six batteries in three parallel series are able to generate 31,51 microwatt at 125,53 microamps. In these types of batteries there is enough power to run biosensors that monitor glucose levels in diabetes patients, detect pathogens in a body or perform other life-saving functions.
