Implantable Fuel Cell Manages Type 1 Diabetes with Excess Glucose

Researchers from ETH Zurich have developed an implantable fuel cell that generates electrical energy from excess glucose in the blood. The fuel cell is combined with artificial beta cells that produce insulin to regulate blood glucose levels. The system autonomously regulates insulin and blood glucose levels and could be used to treat diabetes in the future. The prototype has been successfully tested in mice, but bringing it to market would require an industry partner with the appropriate resources and know-how.
