A battery-free body area network engineered by University of California, Irvine (UCI) researchers integrates advanced metamaterials into flexible textiles to facilitate communication between garments and nearby devices.

"You could potentially keep your phone in your pocket, and just by brushing your body against other textiles or readers, power and information can be transferred to and from your device," said UCI's Peter Tseng.

The researchers extended the network's signal reach beyond four feet using passive magnetic metamaterials built from etched copper-aluminum foils.

UCI's Amirhossein Hajiaghajani said the network could enable secure payments with a single touch or swipe of a sleeve.
