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.
The newly developed cell in the size of a tiny coin is able to generate 0,2 milliwatts of electricity, enough to power a device that measures blood sugar level and transmits data elsewhere, the group said.
