An international team of researchers (Canada, USA – University of Connecticut, UCLA)
has developed a snow-based triboelectric nanogenerator, or snow TENG. A triboelectric nanogenerator, which generates charge through static electricity, produces energy from the exchange of electrons. Snow is positively charged and silicone is negatively charged. When falling snow contacts the surface of silicone it produces a charge that the device captures, creating electricity. After testing a large number of materials including aluminum foils and Teflon, they found that silicone produces more charge than any other material. The research could usher in a new generation of self-powered wearable devices for tracking athletes and their performances. It can also send signals, indicating whether a person is moving…read more.
