Smart agriculture can be deemed as the deep cross-boundary integration of modern information technologies such as Internet of things (IoTs), intelligent equipment, and big data with agriculture, among which the numerous distributed sensors play a vital role in providing precise planting management. However, the lack of efficiency and low-cost energy harvesting approaches to power distributed sensor nodes has become a severe challenge. This challenge will seriously inhibit the development of smart agriculture. Herein, a hybridized energy harvesting device (HEHD) for capturing wind and solar energy was designed by combining two electromagnetic generators (EMGs), two triboelectric nanogenerators (TENGs), and two solar cells (SCs) to enable environmental energy collection. The rotation motion can be transformed into translational motion by introducing a transverse connector to link TENG and EMG, which favors the durability of the TENG. The output performance of TENGs and EMGs increases with increasing wind speed, and the open-circuit voltage (V_OC) and short-circuit current (I_SC) of the individual TENG and EMG can reach up to nearly 570 V, 40 μA, and 0.8 V, 1.85 mA at the 7 ms⁻¹ wind speed, respectively. The self-powered temperature and humidity (Temp&Humid) monitoring system was established by combining the HEHD, a self-developed mobile phone application and a commercial Temp&Humid sensor, which can realize remote monitoring and multi-points connection of farmland environmental Temp&Humid data through the Internet. Moreover, a farm peripheral security alarm system based on the HEHD was constructed to achieve passive remote infrared monitoring. This work makes a beneficial attempt to realize self-powered sensor nodes, indicating broad potential for the use of TENGs in smart agriculture applications.

智慧农业是物联网、智能装备、大数据等现代信息技术与农业的深度跨界融合，其中众多分布式传感器在提供精准种植管理方面发挥着至关重要的作用。然而，功率分布式传感器节点缺乏效率和低成本的能量收集方法已成为一个严峻的挑战。这一挑战将严重抑制智慧农业的发展。在此，通过结合两个电磁发电机（EMG）、两个摩擦纳米发电机（TENG）和两个太阳能电池（SC），设计了一种用于捕获风能和太阳能的混合能量收集装置（HEHD），以实现环境能量收集。通过引入横向连接器连接 TENG 和 EMG，可以将旋转运动转化为平移运动，这有利于 TENG 的耐用性。TENGs和EMGs的输出性能随着风速的增加而增加，并且开路电压（V _OC ) 和单个 TENG 和 EMG 的短路电流 ( I _SC ^{) 在 7 ms -1}时可以达到接近 570 V、40 μA 和 0.8 V、1.85 mA风速，分别。自主研发的手机应用HEHD与商用温湿度传感器相结合，建立了自供电温湿度（Temp&Humid）监测系统，可通过互联网实现农田环境温湿度数据的远程监测和多点连接. 此外，构建了基于HEHD的农场外围安全报警系统，实现了被动式远程红外监控。这项工作为实现自供电传感器节点做出了有益的尝试，表明 TENG 在智能农业应用中的广泛应用潜力。
