无线传感器网络作为遥感、测量、记录和传输科学和工程评估数据的一种手段，正变得越来越普遍，远程和自主。通常，远程传感器节点由电池供电，电池由太阳能或风能收集器充电。有时节点位于由于当地条件而无法进行这些形式的能量收集的地区，例如在森林的树冠下。本文概述了一种能够从树木运动中收集能量的设备的设计和测试，并展示了该设备连续为无线传感器节点供电。该装置利用树干（6米高的树）移动的力和位移来驱动电磁发电机，为镍氢电池充电。电池储存的能量可以持续为一个~ 0.5 mW的无线传感器节点供电。这种演示的能量收集方法可能允许在以前不可能的位置放置和供电节点。
Wireless sensor networks are becoming increasingly more common as a means to sense, measure, record and transmit data for scientific and engineering evaluation, remotely and autonomously. Usually, remotely located sensor nodes are powered by batteries which are recharged by solar or wind energy harvesters. Sometimes nodes are located in areas where these forms of energy harvesting are not possible due to local conditions, such as under the canopy of a forest. This article outlines the design and testing of a device capable of harvesting energy from tree movement, and shows the device powering a wireless sensor node continuously. The device uses the force and displacement of the movement of a tree trunk (of a 6 m tall tree) to drive an electromagnetic generator that recharges a nickel metal hydride battery. The battery stores the energy from which a ∼0.5 mW wireless sensor node is powered continuously. This demonstrated method of energy harvesting may allow the placement and powering of nodes in locations previously not possible.
