An overview of electrospun nanofibers and their application in energy storage, sensors and wearable/flexible electronics

Wearable and flexible electronics are currently a highly demanded and passionate topic of research owing to their excellent combination of related base functions with stretchability and foldability. Textiles are a universal interface and ideal substrate for the integration of nanomaterials, electronics, and optical devices. Smart/e-textiles are fabrics that have been designed and developed with new technologies that provide benefits to the wearer with increased functionality. The rapid development of technology in smart clothing has opened new innovations and is leading to promising applications, such as the ability to communicate with other devices, conduct energy, self-powered sensing, and safeguarding the user from environmental hazards. This review article focuses on the recent developments in the field of smart/e-textiles and mainly gives attention to electrospun nanofiber-based materials and methods used in wearable/flexible electronics, sensors and energy storage.
