The escalating global energy demand necessitates the exploration of renewable energy sources, with wind energy emerging as a crucial and widely available resource. With wind energy exhibiting a vast potential of approximately 1010 kw/a per year, about ten times that of global hydroelectric power generation, its efficient conversion and utilization hold the promise of mitigating the pressing energy crisis and replacing the dominant reliance on fossil fuels. In recent years, Triboelectric Nanogenerators (TENGs) have emerged as novel and efficient means of capturing wind energy. This paper provides a comprehensive summary of the fundamental principles governing four basic working modes of TENGs, elucidating the structures and operational mechanisms of various models employed in wind energy harvesting. Furthermore, it highlights the significance of two major TENG configurations, namely, the vertical touch-separation pattern structure and the independent layer pattern for wind energy collection, emphasizing their respective advantages. Furthermore, the study briefly discusses the current strengths of nano-friction power generation in wind energy harvesting while acknowledging the existing challenges pertaining to device design, durability, operation, and maintenance. The review concludes by presenting potential research directions and prospects for triboelectric nanogenerators generation in the realm of wind energy, offering valuable insights for researchers and scholars in the field.

It is of great significance to establish a low-cost, highefficiency, self-powered micrometeorological monitoring system for agriculture, animal husbandry, and transportation. However, each additional detection element in the meteorological monitoring system increases the power consumption of the whole system by about 0.7 W. As a renewable energy technology, a triboelectric nanogenerator has the advantages of low price and self-powered sensing. To reduce the power consumption of the micrometeorological monitoring system, this work introduces an innovative solution: the wind-gathering enhanced triboelectric-electromagnetic hybrid generator (WGE-TEHG). Coupling the thin-film vibrating triboelectric nanogenerator (TENG) and electromagnetic generator (EMG), the TENG is used to monitor wind direction and the EMG is used to monitor wind speed and provide energy needed by the system. In particular, the TENG can be used as a self-powered sensor to reduce the power consumption of the sensing system. Besides, the TENG is used to produce slit effect to enhance the output performance of EMG. The experimental results show that the WGE-TEHG can build a self-powered natural environment micrometeorological sensing system. It can monitor the wind direction, wind speed, temperature, and relative humidity. This research has great application value for the self-powered sensing implementation of a hybrid TENG and EMG.

“…[26][27][28][29] For the rotating TENGs, the output performance is proportional to the driving torque of the energy harvesting devices. [30] Presently, the rotating TENGs mainly adopt wind cups [31][32][33][34] or windmills [35] to harvest wind energy. Although these types of TENGs have a simple structure, their starting wind speed is relatively high due to the limited driving torque generated by the energy harvesting device.…”

The triboelectric nanogenerator (TENG) is a promising technology with unique advantages for harvesting environmental high‐entropy energy like wind power. However, inefficient wind energy harvest devices have limited the operating wind speed and practical application of TENGs. In this work, a bionic blade lift‐drag hybrid turbine‐driven triboelectric‐electromagnetic hybrid generator (HT‐TEHG) is designed for broadband wind energy harvesting. The lift‐drag hybrid turbine combines the benefits of drag‐type blades enabling low wind speed start‐up and bionic lift‐type blades generating high torque, achieving an 11% increase in performance. The TENGs are designed with appropriate dielectric layer gaps to balance the output performance and friction torque and are independently driven by two types of blades to achieve self‐adaptive graded power generation at different wind speeds. The starting wind speed of the HT‐TEHG is 2 m s−1 and achieves a peak power of 202.4 mW with an energy conversion efficiency of 9.1% at a wind speed of 4 m s−1. The durability of the TENG is verified by continuous operation for 1 × 105 cycles with almost no performance degradation. Moreover, the HT‐TEHG can power a wireless weather station using natural wind. The study introduces a valuable approach to harvest broadband wind energy and enable distributed power for Internet of Things devices.
