Fiber-Based Supercapacitor for Wearable Electronics

Supercapacitors are significant devices that are used for energy storage and also have the capability of delivering energy at a faster rate than batteries. The increase in the significance of portable and wearable electronic equipment giving rise to pace in the development of flexible supercapacitor and flexible electrodes in recent years. A fiber-based supercapacitor (FSCs) is one of the most significant devices which have even helped us give pace knowing the properties of supercapacitor. These FSCs are said to have excellent electrochemical properties and flexibility. This did make function it in different forms of individual fibers or integrated textiles which make it one of the most promising energy storage devices for wearable and portable electronics. This thesis discusses the twisted FSC’s which have been studied using three different commercially available conductive threads ad gel-type electrolytes. The performance of the device was studied at a different number of turns and also lifetime of the device was investigated. Furthermore, the feasibility of the sewing machine is also investigated. The main driving force in developing FSCs is their mechanical flexibility in addition to high capacitive performance. FSCs especially focus on the selection of material, fabrication method its electrochemical, mechanical performance. The future for FSCs based device trends, prospects, also challenges in terms of its fabrication and assembly
