Microbial Fuel Cell power for soft robots.
«The microbes eat organic material and transfer electrons to an anode buried in the sediment,» said Timothy Ewing, the Ph.D. student who helped put together
the microbial fuel cell powering the lights.

Previously, researchers have produced hydrogen gas in
microbial -
powered, batterylike
fuel cells, but only when they supplemented the energy produced by the bacteria with electrical energy from external sources — such as that obtained from renewable sources or burning fossil
fuels, says Bruce Logan, an environmental engineer at Pennsylvania State University, University Park.
A
microbial fuel cell — which generates
power by feeding organic matter (which saliva has lots of) to bacteria, which, in turn, produce electrons — was a natural candidate for their projects.
