A Stretchable Battery to Power Wearable Electronics (VIDEO)
Caption
People flex and bend. Too bad their gadgets can't. Now an experimental battery described in the Nov. 26 edition of Nature Communications promises to do just that. Shown here powering a tiny light, the soft battery maintained a constant power output even when stretched to nearly two times its original length. In laboratory tests it also provided consistent power when squeezed, folded and stretched multiple times. A team led by graduate student David Mackanic, in the lab of Stanford chemical engineer Zhenan Bao, is currently refining its design to generate more power and to prove that the technology can work outside the lab.
