The power source is a bottleneck for the successful development of flexible electronics. Instead of using rigid and bulky batteries, flexible multifunctional devices that store energy and bear loads at the same time provide better solutions by working as powering structural components. Here we demonstrate the woven supercapacitor fabrics featuring high flexibility comparable to that of wearable textiles, high tensile strength of over 1GPa, high failure pressure of 500MPa, and fast charging within seconds. The supercapacitor fabrics can power all kinds of wearable electronics, or be used in other applications that desire load- bearing ability and arbitrary form-factor design for the power systems.
