Printed, Flexible and Rechargeable Battery for Wearables

Our wearables and electronic devices are going to become more flexible in the future. Their batteries will also have to improve. Nanoengineers at the University of California San Diego have developed printed battery that is flexible and stretchable. The ink used to print these batteries is made of zinc silver oxide mixed with SIS, which allows batteries to stretch twice their size in any direction.

This is another step toward self-powered stretchable electronics. The battery capacity is expected to improve in the future though. These batteries can be printed directly on fabric or as a strip to power wearables.
