Binghamton engineer creates origami battery

09.08.2017 | Binghamton University | discovere.binghamton.edu

Origami, the Japanese art of paper folding, can be used to create beautiful birds, frogs and other small sculptures. Now a Binghamton University engineer says the technique can be applied to building batteries, too.

Seokheun “Sean” Choi developed an inexpensive, bacteria-powered battery made from paper. The battery generates power from microbial respiration, delivering enough energy to run a paper-based biosensor with nothing more than a drop of bacteria-containing liquid. “Dirty water has a lot of organic matter,” Choi says. “Any type of organic material can be the source of bacteria for the bacterial metabolism.”

The method should be especially useful to anyone working in remote areas with limited resources. Indeed, because paper is inexpensive and readily available, many experts working on disease control and prevention have seized upon it as a key material in creating diagnostic tools for the developing world. Total cost of this potentially game-changing device? Five cents.
