MIT Glucose Fuel Cell: Proof of Concept Power Source for Brain Implants

MIT researchers have developed a non-biological fuel cell capable of oxidizing glucose and producing up to a milliwatt of power. This particular study was unique because they used cerebrospinal fluid as a glucose source. For reference, there are hearing aids that run on less than a milliwatt of power, and a standard laser pointer requires about five milliwatts of power, and the PS3 Slim uses 96 watts while playing a game.
