Inventors, Chew On This Edible Battery
We recently wrote about Google skin implants that could one day assist in remotely diagnosing sweat and blood samples, a potential breakthrough technology in monitoring and treating diabetes. Recently scientists at Carnegie Mellon University confirmed that they have built a prototype battery out of melanin, a naturally occurring pigment found in our hair, skin and eyes.
“The team built the batteries using melanin and other biocompatible materials such as manganese oxide, copper, and iron. They found that the melanin battery could power a 5 milliwatt device for up to 18 hours,” said Popular Science.

In related news, researchers at MIT, working with other international teams, have demonstrated a tiny origami robot that can unfold itself from a swallowed capsule and, steered by external magnetic fields. It can crawl across the stomach wall to remove a swallowed button battery or patch a wound.
