Fiber material is composed of a group of flexible fibers that are assembled in a certain dimensionality for a broad spectrum of applications. With its good flexibility, high porosity and large surface area, it demonstrates a great potential in development of flexible and wearable electronics for energy harvesting, energy storage and strain sensing. In this talk, the materials, fabrication and mechanisms for fiber-based wearable electronics ranging from nanogenerators, supercapacitors to tensile strain sensors will be introduced and discussed. Their potential applications in the sustainable development and personal healthcare will also be explored.
