在过去的十年中，无线设备的尺寸和功率要求已经减小。这些装置通常使用电池作为电源，但也可以使用其他动力手段，如太阳能、热能或风能。然而，传感器网络通常部署在最小照明和热梯度的条件下，例如茂密的树木环境，即使是正常的风能收集也是有限的。在这些情况下，能量的一个可能来源是树木本身的运动。我们调查了在博福特4级风期间，处于庇护位置的树木运动所产生的能量和功率。我们测量了树举起物体所做的功，我们测量了自由运动的水平加速度，我们确定了树干运动的角偏转，以确定各种类型的收获设备可用的能量和功率。我们发现，从树可用的功率量，如通过提升质量所证明的，与运行无线传感器节点所需的功率相比是有利的。
Over the last decade, wireless devices have decreased in size and power requirements. These devices generally use batteries as a power source but can employ additional means of power, such as solar, thermal or wind energy. However, sensor networks are often deployed in conditions of minimal lighting and thermal gradient such as densely wooded environments, where even normal wind energy harvesting is limited. In these cases a possible source of energy is from the motion of the trees themselves. We investigated the amount of energy and power available from the motion of a tree in a sheltered position, during Beaufort 4 winds. We measured the work performed by the tree to lift a mass, we measured horizontal acceleration of free movement, and we determined the angular deflection of the movement of the tree trunk, to determine the energy and power available to various types of harvesting devices. We found that the amount of power available from the tree, as demonstrated by lifting a mass, compares favourably with the power required to run a wireless sensor node.
