Researchers Prototype NextGen Battery That Will Stretch with Electronics and Implants
by Charles Q. Choi
Imagine batteries stretchy enough to flex inside clothing or under the skin. Unusually elastic batteries could one day help power flexible electronics worn on or implanted inside the body, researchers say.
"Some relatively simple but powerful ideas allow one to construct rechargeable, lithium-ion batteries that have the physical properties of a rubber band," says John Rogers, a materials scientist at the University of Illinois at Urbana-Champaign.
Applications may include robotic skin and wearable health monitors, he added.
