Aerodynamic and aeroelastic flutters driven triboelectric nanogenerators for harvesting broadband airflow energy

The harvest of broadband airflow energy is accomplished using aerodynamic and aeroelastic flutter-driven triboelectric nanogenerators. Multi-layered triboelectric nanogenerators are made by simply stacking single units and can improve the output performance of the device. Adapting an aeroelastic flutter to synergistically combine aerodynamic and aeroelastic movement enables dramatic improvements in the electrical output of the triboelectric nanogenerator.295
