Multi-Tube Helmholtz Resonator Based Triboelectric Nanogenerator for Broadband Acoustic Energy Harvesting
نویسندگان
چکیده
Acoustic energy, especially broadband low-frequency sound energy is part of the environmental mechanical acquisition cannot be ignored. Herein, a multi-tube parallel Helmholtz resonator-based triboelectric nanogenerator (MH-TENG) investigated to reap in noise environments. The designed MH-TENG consists modified resonator and thin-film TENG transducer. core materials transducer are aluminum, FEP film, carbon. To further clarify influence on conversion performance MH-TENG, acoustic characteristics improved resonators systematically studied. A series experiments show that structure has better wave collection effect. Meanwhile, flexible film can reduce optimal output frequency device. power generation bandwidth significantly by adopting resonator. Within range 230 Hz, effectively improve efficiency harvesting. 110 LEDs an electronic thermometer powered sound-driven MH-TENG. In addition, good capacitor charging performance, which conducive its application ambient
