As part of a new project, scientists at China’s National Center for Nanoscience and Technology have developed an innovative triboelectric nanogenerator called STENG that is just as flexible as human skin. Like other triboelectric devices, the contraption produces electricity as a result of friction between two different materials. A paper describing its potential uses has recently been published in the Science Advances journal.
For the uninitiated, the triboelectric effect refers to static electricity that is generated when two materials are rubbed against each other. The flow of surface electrons from one substance to the other is what creates an electrical charge. Made from a mixture of elastomer and an ionic hydrogel, this skin-like transparent device is incredibly flexible, boasting an astounding 1000-percent improvement over conventional triboelectric nanogenerators…
