Scientists have created a customizable, fabric-like power source that can be cut, folded, or stretched without losing its function. The wearable power source, a supercapacitor, works like a fast-charging battery and can be recharged many times.

The "editable" structure and shape can be changed after it is manufactured, while retaining its function as a power source. The supercapacitor can serve as a fabric energy storage device that could be integrated into wearable electronics.
