In article number 1702493 , Su Chen and co‐workers demonstrate high‐performance wearable micro‐supercapacitors based on microfluidically directed nitrogen‐doped graphene fiber electrodes. The key to higher‐performance lies in the microfluidic technique creating a homogeneous environment for fiber production. Resulting fibers form a homogeneous and porous network, possess large specific‐surface‐areas, optimal nitrogen‐active‐sites, and high electrical‐conductivity so that the constructed micro‐supercapacitors can successfully power audio‐visual electronics.
