Improving the efficiency of harvesting electricity from living trees
The harvesting of environmental energy has been attracting more and more attention. In this study, it was observed that there exists electrical potential difference between the phloem of a living tree and the surrounding soil. This kind of bioelectricity is sustained and it can be harvested by charging a capacitor. However, the charging efficiency is greatly dependent on the shape of the electrodes which affects the contact resistance between the electrodes and the phloem significantly. Based on an equivalent circuit model, a method to improve the efficiency of electricity harvesting is proposed. The experimental data demonstrate that this method is feasible and effective.
