18 Jul Electricity from hydrogel
In China and USA, researchers have developed a skin-like, biocompatible triboelectric nanogenerator that is both highly stretchable and transparent.
That object, made by sandwiching a layer of ionic hydrogel (which acts as an electrode) between two elastomer films (which act as an electrification layer), converts mechanical motion into electrical energy.
Moreover, the hydrogel composition is biocompatible which means it could be use for medical applications.
