Edible batteries could power ingestible medical devices

Edible batteries could power ingestible medical devices
Non-toxic, edible batteries could one day power ingestible devices for diagnosing and treating disease. One team reports progress toward that goal with their batteries made with melanin pigments, naturally found in the skin, hair and eyes. The researchers will present their work at the 252nd National Meeting & Exposition of the American Chemical Society (ACS).
