Origami, the Japanese art of paper folding, can be also be applied to building batteries, according to Seokheun “Sean” Choi, an engineer at Binghamton University.

Instead of just creating beautiful birds, frogs and other small sculptures, the technique can be used to develop an inexpensive, bacteria-powered battery made from paper.

Using microbial respiration, the battery generates power to deliver 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.”
