Prosthetics of the future may draw their power from juices in the brain.
These days, the most advanced robotic prosthetics take their commands from the brain. And pretty soon, they may be drawing their power from juices in the brain. Cerebrospinal fluid, that is. Electrical engineers at the Massachusetts Institute of Technology are developing a novel platinum-coated fuel cell that runs off the glucose found in bodily fluids. Their specific aim is to implant the fuel cells in liquid pockets of the brain and use them to run low powered components in a neural prosthetic. They described a prototype this week in the journal PLoS One.
