Shocking Sheets: Power paper packs a punch

A new, ultrathin material made from cellulose, the main ingredient in paper, could power future electronic gadgets, medical implants, and even hybrid vehicles. Developed by researchers at Rensselaer Polytechnic Institute in Troy, N.Y., the material can be rolled into a tube, folded, and cut into different shapes with no effect on its function.

"This new, paperlike energy device could fundamentally change the way we power things," says Ning Pan, a materials scientist at the University of California, Davis.
