Researchers at the Massachusetts Institute of Technology make glucose powered bio-electronics a reality. They have developed a fuel cell that runs on glucose for powering highly efficient brain implants of the future that can help paralyzed patients move their arms and legs again. The fuel cell strips electrons from glucose molecules to create a small electric current.
The researchers fabricated the fuel cell on a silicon chip, allowing it to be integrated with other circuits that would be needed for a brain implant. The glucose fuel cell, when combined with such ultra-low-power electronics, can enable brain implants or other implants to be completely self-powered. Thus making brain glucose as a new energy source for future medical implants.
