It is of great significance to establish a low-cost, high-efficiency, 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.
建立一个低成本、高效率、自供电的用于农业、畜牧业和交通运输业的微气象监测系统具有重要意义。然而，气象监测系统中每增加一个检测元件，整个系统的功耗就会增加约0.7W。作为一种可再生能源技术，摩擦纳米发电机具有价格低廉和自供电传感的优点。为了降低微气象监测系统的功耗，这项工作引入了一种创新解决方案：聚风增强型摩擦-电磁混合发电机（WGE-TEHG）。通过将薄膜振动摩擦纳米发电机（TENG）和电磁发电机（EMG）耦合，TENG用于监测风向，EMG用于监测风速并提供系统所需的能量。特别地，TENG可作为自供电传感器来降低传感系统的功耗。此外，TENG用于产生狭缝效应以增强EMG的输出性能。实验结果表明，WGE-TEHG能够构建一个自供电的自然环境微气象传感系统。它可以监测风向、风速、温度和相对湿度。这项研究对于混合TENG和EMG的自供电传感实现具有很大的应用价值。
