A flexible self‐charging power system is built by integrating a fiber‐based supercapacitor with a fiber‐based triboelectric nanogenerator for harvesting mechanical energy from human motion. The fiber‐based supercapacitor exhibits outstanding electrochemical properties, owing to the excellent pseudocapacitance of well‐prepared RuO 2 · x H 2 O by a vapor‐phase hydrothermal method as the active material. The approach is a step forward toward self‐powered wearable electronics.
