Abstract

The power supply for numerous small electronic sensors, which are extensively used in agricultural settings, is a critical challenge for advancing the Agricultural Internet of Things (IoT) and fostering the development of smart agriculture in the upcoming era of intelligent technology. Hereby, a triboelectric-electromagnetic hybrid wind energy harvesting and sensing device (TEH-WSD) based on triboelectric-electromagnetic hybrid generator (TEHG) and multi-channel triboelectric nanogenerator (MC-TENG) for wind direction and speed sensing is proposed. Among them, the TEHG is used to collect wind energy. The instantaneous peak power of TENG units and EMG unit in TEHG can reach 5.95 mW and 5.65 mW respectively. In addition, the modified TEHG can measure the wind speed within the range of 3–5 m/s, and the output signal of MC-TEHG can be used to measure the wind direction based on the corresponding circuit and designed program continuously. Overall, TEH-WSD is capable of detection for the wind direction, wind speed, temperature and humidity information in the environment and this work provides a solution for wind energy collection and self-powered environmental monitoring in agricultural environment.

用于自供电智能农业监测的三电-电磁混合风能收集和多功能传感装置

在即将到来的智能技术时代，农业环境中广泛使用的众多小型电子传感器的供电问题是推进农业物联网（IoT）和促进智能农业发展的关键挑战。为此，我们提出了一种基于三电-电磁混合发电机（TEHG）和多通道三电纳米发电机（MC-TENG）的三电-电磁混合风能采集与传感装置（TEH-WSD），用于风向和风速传感。其中，TEHG 用于收集风能。TEHG 中的 TENG 单元和 EMG 单元的瞬时峰值功率分别可达 5.95 mW 和 5.65 mW。此外，改进后的 TEHG 还能测量 3-5 m/s 范围内的风速，MC-TEHG 的输出信号可用于根据相应电路和设计程序连续测量风向。总之，TEH-WSD 能够检测环境中的风向、风速、温度和湿度信息，为农业环境中的风能收集和自供电环境监测提供了一种解决方案。
