"Forget those old, bulky electrodes of the past. Researchers have created a device that can track your heart, brain and muscle activity as effectively as conventional monitoring systems -- and is thin enough to be laminated onto the skin like a temporary tattoo. Down the line, such electronic patches could be used to monitor vital functions, aid in physical rehabilitation or perhaps be deployed in covert military operations.
John Rogers, a materials scientist with the University of Illinois at Urbana-Champaign, discussed the research and its potential future uses.
How did you make such a thin, flexible, stretchable electronic device?"
