Professor Kim Jin-kon (CE), Sandip Maiti (CE, Ph.D), and Professor Khatua (IIT Kharagpur) researched together to create piezoelectric elements created from the cellulose fiber in onion peels. The research team figured that the crystalline structure of the cellulose fiber could be used in piezoelectric materials, and focused on onion peels, one of the abundant sources of cellulose fiber. After the conduction of experiments, the team found out that the energy could be produced with onion peels, and successfully create a sensitive, efficient piezoelectric element that could produce electricity with the movement of a leaf.
Prof. Kim said, “We created a method of generating energy with natural materials, without damaging the environment.” He also showed his expectations, that “This research will be the groundwork for energy supplication methods of future devices, such as wearables.”
