Woven wearable energy storage materials

Are flexible power sources suitable for wearable electronics?

Flexible power sources with load bearing capability are attractive for modern wearable electronics. Here, free-standing supercapacitor fabrics that can store high electrical energy and sustain large mechanical loads are directly woven to be compatible with flexible systems.

Can wearable energy-storing textiles withstand harsh deformation?

As for wearable energy-storing textiles, it can withstand harsh deformation. Five yarn SCs were connected in series and were woven into a piece of fabric together with common cotton yarns. This soft energy-storing fabric can light a red light-emitting diode (LED).

Can wearable electronic textiles store capacitive energy?

Wearable electronic textiles that store capacitive energy are a next frontier in personalized electronics. However, the lack of industrially weavable and knittable conductive yarns in conjunction with high capacitance, limits the wide-scale application of such textiles.

Will flexible and wearable energy storage devices provide power support?

Flexible and wearable energy storage devices are expected to provide power support for the burgeoning smart and portable electronics.

Can a rechargeable energy storage device be integrated into wearable electronic systems?

One strategy is to directly integrate a conventional rechargeable energy storage device, such as a battery or a supercapacitor (SC), into fabrics (7 – 10). This self-powered system is a favorable power platform to be integrated into wearable electronic systems.

Are knitted MXene-based TSCs a practical application of wearable energy storage devices?

Furthermore, knitted MXene-based TSCs demonstrated practical application of wearable energy storage devices in textiles. Herein, the techniques used to produce MXene-based fibers, yarns, and fabrics and the progress in architecture design and performance metrics are highlighted.
