摘要

Environmental monitoring of local climatic variations plays a vital role in theresearch on global warming, species diversity, ecological sustainability, andso on. Traditional monitoring technologies, such as meteorological stationsor satellite imagery, can give an overall environment picture but at highcost, high energy consumption, and with insufficient regional details. Here,a networking system made of low-cost, maintenance-free, and distributedself-powered wireless monitoring nodes is proposed, aimed at establishinga sensing system for long-term and wide-area environment monitoring. It isdemonstrated that, as driven by gentle wind, these distributed nodes are ableto monitor temperature, humidity, and atmospheric pressure automatically,and then transfer the sensing data to receiving terminals wirelessly usingtriboelectric nanogenerators as energy harvesting technologies. Thelongest transmitting distance is 2.1 km. Additionally, a sensing networkis formed. By utilizing several nodes, a 2-km~2 region is covered, and theinformation can be transmitted live using a relay-technology. Furthermore,the node is demonstrated to work for weeks, and continuously send backenvironmental data. Since the nodes are portable and the embeddedsensors are customizable, it is anticipated that the system can bemultifunctional and applied in many natural areas, such as forests, prairies,mountains, lake regions, and so on.
