Last year a team of engineers from MIT and Harvard has developed an origami flat-pack robot[youtube.com] which can fold itself and crawl away without any human intervention. But now a Binghamton University engineer says this technique can be applied to building batteries, too. 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. This method should be especially useful to anyone working in remote areas with limited resources. The total cost of this potentially game-changing device is "five cents."
