Fuel cell for prosthetics runs on blood

IOL: Science & Tech: "A Japanese research team has developed a fuel cell that runs on blood without using toxic substances, opening the way for use in artificial hearts and other organs.

The biological fuel cell uses glucose, a sugar in blood, with a non-toxic substance used to draw electrons from glucose, said the team led by Matsuhiko Nishizawa, bio-engineering professor at the graduate school of state-run Tohoku University.
