Implantable fuel cell built at MIT could power neural prosthetics that help patients regain control of limbs. MIT engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again. Read more...
This silicon wafer consists of glucose fuel cells of varying sizes; the largest is 64 by 64 mm.
