U.S. scientists have used inexpensive store-bought tape to craft a triboelectric nanogenerator (TENG), which is capable of harvesting electrical energy from various sources, including human movement and environmental conditions, to power small devices like wearable biosensors.
Using triboelectric effect, TENGs convert mechanical energy, such as friction or movement, into electricity.
Researchers from the University of Alabama in Huntsville (UAH) revealed that the triboelectric generator was proposed using commercial tape materials, which are composed of metalized poly(ethylene terephthalate) films to serve as electrodes and Scotch tape layers for power generation.
They highlighted that the power extraction is achieved by the interaction between polypropylene and the…
