New Operation? Italian Scientists Use Plant Power To Light Up LED Bulbs

- Dec 19, 2018-

Scientists have reportedly developed a way to use living plants to generate electricity to light up LED bulbs, providing a "green" solution for sustainable power generation. The plant that generates electricity is made of natural and artificial leaves. When the wind blows on the plant and moves the leaves, it generates electricity.——LED Christmas light


Interdisciplinary roboticists and biologists from IIT-Istituto Italiano di Tecnologia, Pontedera, Pisa, Italy, have found that living plants can help generate electricity. Moreover, the results have been published in the Journal Advanced Functional Materials.——LED Christmas light


The team led by Fabian Meder found that living plants can generate more than 150 volts of electricity from a single leaf, enough to light 100 LED bulbs at the same time. Researchers have also shown that hybrid trees made from natural and artificial leaves can be used as innovative "green" generators to convert wind power into electricity.——LED Christmas light


In the last study, the team studied plants and found that leaves generate electricity when touched by different substances or wind.——LED Christmas light


Most plant leaves naturally provide specific components, so some leaf structures can convert mechanical forces applied to the leaf surface into electrical energy. Specifically, due to the process of contact electrification, the blade can collect electricity on its surface. The electricity is then immediately transferred to the internal tissues of plants. Plant tissues act like "cables" and transmit the resulting electricity to other parts of the plant. Therefore, as long as the "plug" is simply connected to the plant stalk, the generated electricity can be collected to power the electronic equipment.——LED Christmas light


In this paper, researchers also describe for the first time how to use this effect to convert wind power into electricity. So researchers modified an oleander tree to touch natural oleander leaves with artificial leaves. Hybrid trees generate electricity when the wind blows toward plants and moves leaves. The more electricity you generate, the more leaves you touch. Thus, by developing the entire surface of a tree or even a leaf in a forest, it is easy to scale up.——LED Christmas light
