With the rapid growth of the Internet of Things, intelligent agriculture is becoming increasingly important. Traditional agricultural monitoring methods, which rely on fossil fuels and complex wiring, hinder progress. This work introduces a hybrid nanogenerator based on a rotational-swinging mechanism (RSM-HNG) that combines triboelectric nanogenerators (TENGs) and electromagnetic generators (EMGs) for efficient wind energy harvesting and smart agriculture monitoring. The parallelogram mechanism and motion conversion structure enable the stacking and simultaneous contact-separation of multiple TENG layers. Moreover, it allows the TENG and EMG units to operate simultaneously, which improves energy harvesting efficiency and extends the system's lifespan compared to traditional disc-based friction wind energy harvesting methods. With four stacked layers, the short-circuit current of the TENG increases from 16 μA to 40 μA, while the transferred charge rises from 0.3 μC to 1.5 μC. By optimizing the crank angle, material selection, and substrate structure, the output performance of the RSM-HNG has been significantly enhanced. This technology powers a self-sustaining wireless monitoring system for temperature, humidity, an electronic clock, and road guidance. The RSM-HNG provides continuous energy for smart agriculture, animal husbandry, and environmental monitoring, all driven by wind energy. It holds great potential for regions with abundant wind resources but limited electricity access, offering valuable applications in these areas.
随着物联网的迅速发展,智能农业变得越来越重要。依赖化石燃料和复杂布线的传统农业监测方法阻碍了发展进程。这项工作介绍了一种基于旋转摆动机构的混合纳米发电机(RSM-HNG),它结合了摩擦纳米发电机(TENG)和电磁发电机(EMG),用于高效的风能采集和智能农业监测。平行四边形机构和运动转换结构使多个TENG层能够堆叠并同时进行接触-分离。此外,它允许TENG和EMG单元同时运行,与传统的基于圆盘的摩擦风能采集方法相比,提高了能量采集效率并延长了系统的使用寿命。有四层堆叠时,TENG的短路电流从16 μA增加到40 μA,而转移电荷从0.3 μC增加到1.5 μC。通过优化曲柄角度、材料选择和基板结构,RSM-HNG的输出性能得到了显著提高。这项技术为温度、湿度、电子时钟和道路引导的自维持无线监测系统提供动力。RSM-HNG为智能农业、畜牧业和环境监测提供持续能源,所有这些都由风能驱动。它在风能资源丰富但电力供应有限的地区具有巨大潜力,在这些领域提供了有价值的应用。
