Nanogenerators Could Charge Your Smartphone
Researchers at the Georgia Institute of Technology have been exploring the applications and commercial potential for triboelectric nanogenerators (TENGs) since 2012. These so-called TENGs essentially harvest static electricity from friction.
Now a team of researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea have overcome one of the hurdles preventing the technology from gaining wider adoption: low power output. To do this, they have developed a new polymer that serves as a dielectric material.
