sugar, s’not so bad

“The implants of the future will be powered by the energy sources already inside your body. Last week we saw scientists take a step toward this vision by developing a transistor that used the fuel from our cells (a molecule called ATP). And now, a French team has announced the development of a fuel cell that can use the glucose (sugar) inside an animal to produce electricity. Their paper is available free at the journal PLoS One.”
