Fabian Meder, Barbara Mazzolai and iheir co-workers at IIT discovered that living plants are “ green

24、” power source,which may :become one of futures electricity supplies that perfectly produces in natural environments and is accessible all over the world. Results are published on Advanced Functional Materials. They discovered that plants can produce, by a single leaf, more than 150 volts each time

25、the leaf is touched, enough to power 100 LED light bulbs. They also showed that an “hybrid tree” made of natural and artificial leaves can act as an “green” electrical producer transferring wind into electricity. Certain leaf structures are able to transform mechanical（机械的） forces applied at the lea

26、f surface into electrical energy, because of the specific composition that most plant leaves naturally provide. In detail, the leaf is able to gather electric charges on its surface due to a process called contact electrification. These charges are then immediately passed into the inner plant tissue

27、. The plant tissue transports the electricity to other parts of the plant. And then, by simply connecting a “ plug” to the plant stem（茎）, the electricity produced can he harvested and used to power electronic devices. The researchers additionally describe for the first time how this effect can be us

28、ed to transfer wind into electricity by plants. They equipped a Nerum oleander tree（夹竹桃） with artificial leaves that touch the natural Nerum oleander leaves.
