Researchers Build Water Soluble Chips 52

angry tapir writes "Researchers in the U.S. have developed integrated circuits that can stick to the skin like a child's tattoo and in some cases dissolve in water when they're no longer needed. The 'bio chips' can be worn comfortably on the body to help diagnose and treat illnesses. The circuits are so thin that when they're peeled away from the body they hang like a sliver of dead skin, with a tangle of fine wires visible under a microscope. Similar circuits could one day be wrapped around the heart like 'an electronic pericardium' to correct irregularities such as arrhythmia."
