As our tech needs grow and the Internet of Things increasingly connects our devices and sensors together, figuring out how to provide power in remote locations has become an expanding field of research.

Professor Seokheun “Sean” Choi—a faculty member in the Department of Electrical and Computer Engineering at Binghamton University’s Thomas J. Watson College of Engineering and Applied Science—has been working for years on biobatteries, which generate electricity through bacterial interaction.
One problem he encountered: The batteries had a lifespan limited to a few hours. That …
