High-performing honeycomb-structured triboelectric nanogenerator enhanced by triple electrodes for utilizing wind power

The utilization of wind power and other renewable resources is attracting more and more attention worldwide in response to climate change. However, the majority of energy-converting facilities are usually frail and susceptible to natural factors, which leads to inefficient and inconsistent operation. Here, originating from bionics and nanotechnology, the honeycomb-structured triboelectric nanogenerator with triple-electrode is proposed, permitting long-term efficient and stable working cycles. A simple power management strategy is implemented to enhance the output current by 42.1%. The overall structure exhibits high power density (291.5 W/m3) and motivating ability under low rotational speed (60 rpm), excellent force resistance and specific energy absorption (4.03×104 J/m3), as well as flexible integration. Further, a wireless wind speed detection system is managed to monitor the changeable wind conditions intelligently. This work illuminates a feasible and effective solution for converting wind power into electricity on a large scale, providing a feasible solution to the energy crisis.
