摘　　要：环境能量采集课题的研究已经得到大量学者的持续关注。主要讨论了植物中所存在的电能以及植物电能的采集效率问题。实验测试发现植物中不同部位之间以及植物与土壤之间均存在电势差。基于此,提出了一种简单的植物电能采集方法,该方法采用给电容充电的方式来采集植物中存在的电能。重点研究了该采集方法的采集效率,实验结果表明该方法采集效率的高低依赖于电极的形状,这是由于电极的形状会直接影响电极与树木和土壤之间的接触电阻的大小。最后还讨论了研究的一些潜在应用。The study on energy harvesting from surrounding environment has been attracting researchers＇ interests. The electricity in living trees is measured and the efficiency of electricity harvesting from trees are mainly discussed. From the experimental tests,it can be found that there exists electrical potential difference between not only different parts of a tree ,but also such parts and the surrounding soil. Based on the observation,a simple method is proposed to harvest the electricity from the living trees by charging a capacitor. The charging effwiency is analyzed in the research. The experimental results show that the e ftciency is greatly dependent on the shape of the electrodes which affects the contact resistance between the electrodes and the tree significantly. Some potential applications of the findings are briefly discussed.
