Portable electronics have brought ease and convenience to our lifestyles and are mostly held or worn by our bodies. They are used for different functions, including sensors, controllers, displays, and many others. These devices need power to operate and function. The most convenient power supply is wearable flexible batteries capable of delivering charge and remaining gentle to the users. This chapter introduces various fabrication techniques for fiber electrodes and the strategies to integrate them into fully wearable batteries and structures.
