Triboelectric-electromagnetic hybrid nanogenerator (HNG) exhibits exceptional output performance, rendering it a highly viable solution for powering tiny electronics in the foreseeable future. However, the construction of a simple structure and light weight HNG using magnetizable triboelectric materials is a highly desirable yet challenging task. Herein, we present a HNG based on flexible neodymium iron boron/polyvinyl chloride (Nd2Fe14B/PVC) composite films for efficiently harvesting mechanical energy from the environment. By embedding Nd2Fe14B powder in PVC matrix, the as-prepared Nd2Fe14B/PVC composites possess desirable triboelectricity and magnetic strength, which is advantageous in replacing traditional heavy magnets to construct a lightweight HNG with high performance. Under a force of 3.8 N and a frequency of 2.1 Hz, the triboelectric nanogenerator (TENG) produces an output power of 4.5 mW at a loading resistance of 5 MΩ, while the electromagnetic generator (EMG) generates up to 0.11 mW at a loading resistance of 200 Ω. The HNG exhibits superior stability and better charging performance compared to single energy harvesting units. A commercial 470 μF capacitor can be charged to 3 V within 385 s through the HNG, which can continuously supply electrical energy to a hygrothermograph and vernier scale. This work provides an effective method for preparing magnetizable triboelectric materials and introduces new possibilities for the rational design of simple structure and lightweight HNGs. A light-weight and stable hybridized triboelectric-electromagnetic nanogenerator with high-performance is designed based on flexible neodymium iron boron/polyvinyl chloride (Nd2Fe14B/PVC) composite film, which can continuously provide electrical energy for a hygrothermograph and vernier scale.
