Over the years, the telephone has gone mobile, from the house to the car to the pocket. The University of South Carolina’s Xiaodong Li envisions even further integration of the cell phone -- and just about every electronic gadget, for that matter -- into our lives. He sees a future where electronics are part of our wardrobe. “We wear fabric every day,” said Li, a professor of mechanical engineering at USC. “One day our cotton T-shirts could have more functions; for example, a flexible energy storage device that could charge your cell phone or your iPad.”
