Intelligent glass for railways manufactured using sputtering techniques

The aim of the project is the development of electrochromic side windows: the project aims to develop windows based on electrochromic glass manufactured entirely by layer deposition using magnetron sputtering and that can be easily industrialised at the Ariño facilities. Electrochromic glass has the peculiarity of changing its light transmission properties when a small electrical current is applied to it. This type of smart glass allows users to control the amount of light (and, consequently, heat) that they transmit, representing considerable energy savings. Once activated, the glass changes from transparent to opaque, partially blocking light while maintaining a clear view, offering the passenger the possibility to modify the state of the window with the push of a button, and resulting in greater comfort.
