摘　　要：对无线传感器网络节点的能量供应及其管理技术的现状进行了讨论。分析研究了无线传感器网络节点的能量收集原理、技术与方法,认为无线传感器网络节点能量管理应从节能与供能两方面去解决。对环境中存在的各种能源的收集原理与方法进行了分析,这些能源包括太阳能、风能、声能、振动、热电以及电磁场能等。最后提出了传感器节点应该采用尽可能多的方法从环境中吸取能量,以确保传感器节点能够长期、稳定、可靠地工作。The statu of energy supply and management of WSN node was discussed, and the principle, technique and method of energy harvesting were analyzed. The results show that energy saving and sup- plying are two aspects to solve the problems of energy management of WSN node. The harvesting princi- ple and method of various energy existed in environment were sunlmarized, such as solar energy, wind energy, sound energy, vibration energy, thermoelectric energy, electromagnetic energy and etc. In order to make WSN node work well, long and reliably, energy harvesting methods adopted as many as possible from environment for WSN node was proposed.
