Supercapacitors for Wearable Devices

Researchers have engineered a novel type of supercapacitor that remains fully functional even when stretched to eight times its original size. It does not exhibit any wear and tear from being stretched repeatedly and loses only a few percentage points of energy performance after 10,000 cycles of charging and discharging. The supercapacitor could be part of a power-independent, stretchable, flexible electronic system for applications such as wearable electronics or biomedical devices.
