Harvesting Energy From Glucose in Cerebrospinal Fluid to Power Brain Implants of the Future

The new fuel cell is fabricated from silicon, using the same technology used to make semiconductor electronic chips, with no biological components.

A platinum catalyst strips electrons from glucose, mimicking the activity of cellular enzymes that break down glucose to generate ATP, the cell’s energy currency. (Platinum has a proven record of long-term biocompatibility within the body.)

So far, the fuel cell can generate up to hundreds of microwatts — enough to power an ultra-low-power and clinically useful neural implant.
