Abstract Following the rapid development of lightweight and flexible smart electronic products, providing energy for these electronics has become a hot research topic. The human body produces considerable mechanical and thermal energy during daily activities, which could be used to power most wearable electronics. In this context, fiber‐based energy conversion devices (FBECD) are proposed as candidates for effective conversion of human‐body energy into electricity for powering wearable electronics. Herein, functional materials, fiber fabrication techniques, and device design strategies for different classes of FBECD based on piezoelectricity, triboelectricity, electrostaticity, and thermoelectricity are comprehensively reviewed. An overview of fiber‐based self‐powered systems and sensors according to their superior flexibility and cost‐effectiveness is also presented. Finally, the challenges and opportunities in the field of fiber‐based energy conversion are discussed.
