“…9e and h, both structures exhibit an increase in output voltage with higher wind speeds, eventually reaching a plateau. This trend has also been confirmed by the works of Xu, 117 Liu, 118 Wang, 119 Cui, 120 etc. Moreover, the impact of wind turbulence intensity on the power generation performance of the TENG unit is investigated, as shown in Fig.…”

“…The PTFE structure was designed with a hemispherical bottom in order to increase the contact area of the friction material, thereby increasing the triboelectric charge density of the TENG. In addition, Zhu et al developed a continuous DC nanogenerator using one-way charge transport and doublecross TENG, as shown in Figure 6c [107]. The rotating disc was composed of porous cloth and the intermediate material cloth was assembled with an acrylic ring [108,109], while a dielectric pair was connected to the top stator.…”

With the continuous advancement in technology, electronic products used in augmented reality (AR) and virtual reality (VR) have gradually entered the public eye. As a result, the power supplies of these electronic devices have attracted more attention from scientists. Compared to traditional power sources, triboelectric nanogenerators (TENGs) are gradually being used for energy harvesting in self-powered sensing technology such as wearable flexible electronics, including AR and VR devices due to their small size, high conversion efficiency, and low energy consumption. As a result, TENGs are the most popular power supplies for AR and VR products. This article first summarizes the working mode and basic theory of TENGs, then reviews the TENG modules used in AR and VR devices, and finally summarizes the material selection and design methods used for TENG preparation. The friction layer of the TENG can be made of a variety of materials such as polymers, metals, and inorganic materials, and among these, polytetrafluoroethylene (PTFE) and polydimethylsiloxane (PDMS) are the most popular materials. To improve TENG performance, the friction layer material must be suitable. Therefore, for different application scenarios, the design methods of the TENG play an important role in its performance, and a reasonable selection of preparation materials and design methods can greatly improve the work efficiency of the TENG. Lastly, we summarize the current research status of nanogenerators, analyze and suggest future application fields, and summarize the main points of material selection.

“…The ventilation monitoring system's initial node of data collection is the mine wind velocity sensor. The mine roadway's high temperature and high humidity environment may easily have an impact on data gathering, leading to poor accuracy wind velocity data [4,5]. Therefore, the design and development of high-precision wind velocity sensors for mining must take into account adapting to the subterranean high temperature and high-humidity environment.…”

The design and development process of wind velocity sensors for mining has been a challenging task due to the complexity of a large number of field tests. To resolve this problem, this study aimed to provide a comprehensive test device for the design and development of high-precision wind velocities sensor for mining. Through a combination of experiments and computational fluid dynamics (CFD), a device that can simulate the mine roadway environment was developed. The device can control the temperature, humidity, and wind velocity parameters to fully replicate the mine roadway environment. It gives designers and developers of high-precision wind velocity sensors for mining a rational and scientific testing environment. In order to quantitatively define the uniformity of air flow in the mine highway section, the research introduced the non-uniformity determination method. The approach was expanded to assess the cross-sectional uniformity of temperature and humidity. The wind velocity within the machine can increase to 8.5 m/s by selecting the right kind of fan. The minimum wind velocity non-uniformity at this moment is 2.30%. The device’s internal temperature can be raised to 38.23 °C and its humidity level can be increased to 95.09% by carefully crafting the rectifier orifice plate’s structure. At this time, the lowest temperature non-uniformity is 2.22%, and the lowest humidity non-uniformity is 2.40%. The device’s average wind velocity is 4.37 m/s, its average temperature is 37.7 °C, as well as its average humidity is 95%, per the emulate results. The device’s non-uniformity in wind velocity, temperature, and humidity is 2.89%, 1.34%, and 2.23%, respectively. It is capable of simulating the mine roadway environment in its entirety.
