Batteries with the same probiotics found in yogurt and dietary supplements produce more than 100 minutes of electricity, then dissolve in their surroundings.
The batteries were developed by a team led by researchers at Binghamton University in the UK and are made using water-soluble paper.
This battery is used in biomedical and environmental fields, but must be disassembled in an environmentally friendly manner. To prevent the release of toxins into the environment, the main challenge is changing the power source. However, most power sources, such as lithium batteries, contain toxic substances.
The battery has a power source that goes out without leaving any toxic residues. The battery has been in work for 20 years, and Binghamton University alumni, Maedeh Mohammadifar, was a member of the Soluble Microbial Fuel Cell Research Group, which first assisted in the design.
The new battery is equipped with commercially available probiotics that dissolve harmlessly and release only beneficial microorganisms. Energy delivery times can be adjusted from four minutes to more than 100 minutes, she said, adding that the battery can be used with biomedical implants, environmental sensors and disposable electronic devices.
Probiotics are living microorganisms that when consumed offer health benefits and are harmless to the environment and humans. New research by Iranian scientists Maeda Mohammadifar and Maryam Rezaei shows the possibility of using probiotics to develop new soluble batteries.
