“Melt in the body” medical electronics devised

Ultra-thin electronics that dissolve inside the body have been devised by scientists in the U.S. and could be used for a range of medical roles, including heating a wound to keep it free from infection by bacteria. This has been the first use for the electronics, which scientists speculate could also be used to build sensors for the brain and heart and to slowly release drugs inside the body. They may be useful for non-health related matters, too: picture the cell phone embedded with this handy bit of engineering, able to dissolve autonomously instead of languishing in a landfill for years.
