Researchers at the Centre for Micro-Bio Robotics of IIT in Pontedera in Italy have discovered that certain plants generate electricity when touched that can power up to 100 LEDs (150V) per leaf. The leaves gather electric charges on their surface as a result of contact electrification and transmit the current directly to the stem of the plant, which can then be harvested. the researchers built a hybrid Nerum oleander tree with artificial leaves that touch the natural leaves and generate electricity.
