Scientists have created "electronic foils" that will allow circuits to conform to any surface — or get stretched, bent, and crumpled. The electronics may someday become as common as plastic wrap, researchers say.
In recent years, we've seen a number of breakthroughs in softer, flexible electronics. Much of the work is spearheaded by the uber-productive John Rogers, a materials scientist at the University of Illinois at Urbana-Champaign. A few months ago, Rogers and his colleagues developed stretchy, bendable batteries to power a new generation of flexible displays, solar panels and other devices.
