Dubbed a glucose biofuel cell, the implant gets its juice from glucose—aka blood sugar—and oxygen, both of which are naturally present in the fluids between a body's cells.
In a recent study, researchers created a test version of their glucose biofuel cell and implanted it in a white lab rat named Ricky. The rat sported the device successfully for 11 days and suffered no ill effects.

Electronics keep shrinking, as "embedded technologies" like microchips grafted to the skin and computer monitor contact lenses have surged over the last decade. But how can engineers generate enough energy to run such mystifyingly compact, yet complex gadgets?
In Smithsonian Magazine's August issue, an article details how the Defense Advanced Research Projects Agency (DARPA)—the U.S. Department of Defense agency that helped fund the development of computer networking, the first hypertext system, and global positioning—is trying to deal with the battery problem: Their Energy Starved Electronics program, founded in 2005 with MIT researchers, seeks to utilize the human body itself as the power source.
