Recent advances in functional fiber electronics

Abstract

Rapid development of wearable electronics with various functionalities has stimulated the demand to construct functional fiber devices due to their merits of mechanical flexibility, weavability, miniaturization, and integrability. To this end, fiber components which can realize the functions of energy storage and conversion, actuating plus sensing have gained increasing concerns. Herein, we summarize the recent progress with respect to fiber material preparation, innovative structure design, and device performance in this review, also highlighting the possibility of integrated fiber electronics as an extension of application, the remaining challenges and future perspectives toward next‐generation smart systems and to facilitate their commercialization.
