Professor. Z. L. Wang and Dr. X. D. Wang of the Georgia Institute of Technology have developed a nano generator that generates electricity by moving your arm or take a walk. Even the beating of the hart can generate electricity to charge your iPod or cell Phone.
"This research will have a major impact on defense technology, environmental monitoring, biomedical sciences and even personal electronics," says lead researcher Zhong Lin Wang, Regents' Professor, School of Material Science and Engineering at the Georgia Institute of TechnologyThe main advantage is that those nano wires can grow on a large variety of surfaces.
