A novel magnetic force-driven noncontact triboelectric nanogenerator (TENG) for scavenging biomechanical energy to sustainably power-portable electronics is presented. PVDF fiber membrane with Fe3O4 nanoparticles embedded, based on the electrospun, is employed as a triboelectric layer. A magnet is utilized as the trigger to drive contact-separation mode TENG in a noncontact way due to the magnetic responsiveness of triboelectric materials. TENG with a small dimension has a peak output power of 0.23 mW under a load resistance of 25 MΩ. It exhibits a good stability for the output and charging performance, so it can be utilized to charge energy storage devices and sustainably power some portable electronics.
