Researchers Generate Electricity From Viruses

First time accepted submitter toomuchtogrok writes "Imagine charging your phone as you walk, thanks to a paper-thin generator embedded in the sole of your shoe. This futuristic scenario is now a little closer to reality. Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display. It works by tapping a finger on a postage stamp-sized electrode coated with specially engineered viruses. The viruses convert the force of the tap into an electric charge."

Thee viruses convert the force

I was thinking of Midichlorians, when I read it but I have no idea where I got it from I do not remember it any of the three Star War Movies.

Why this is better than existing piezo

That question sadly went unanswered in the summary, but is discussed in the article. The viruses are preferable because making existing piezoelectrics is apparently difficult and requires toxic chemicals, while these viruses are self-replicating bacteriophages. They are also under the right conditions self-organizing, making the creation of piezo film easy by comparison. Looks like there's a long way to go to get a decent amount of electricity out of them, though.
