Recent Advances in Functional Fabric-Based Wearable Supercapacitors

Abstract

With the advent of wearable electronics, the urge to devise new and flexible energy storage devices to power up wearable systems has steadily risen over the past few decades. Wearable fabric-based supercapacitors have emerged as a fantastic solution for powering up these systems. Functionalizing fabric surfaces with electroactive materials has proven to be the ideal way to fabricate high-performance wearable supercapacitors. In this review, the recent progress in functional fabric-based wearable supercapacitors is summarized. The article begins with the introduction of different fabric structures and outlining the functional materials implemented in wearable supercapacitors. The emphasis shifts toward summarizing the fabrication of functional fabric-based electrodes according to different fabric architectures. Then, different novel fabric-based supercapacitor configurations, the current state of integration, and the durability of such devices are analyzed. The review is concluded by emphasizing the existing drawbacks, envisaging potential applications, and, most importantly, the future perspective of the technology.
