In the simplest definition, smart glass technologies alter the amount of light transmitted through typically transparent materials, allowing these materials to appear transparent, translucent or opaque with a push of a button or the wave of a hand. Smart glass is dynamic, allowing a traditionally static material to become alive and multi-functional. This technology allows for the control of various forms of light, including visible light, ultraviolet and infrared.
Currently, smart glass is increasingly recognized worldwide for its ability to provide instant privacy, impressive energy-saving benefits and a modern, sleek appearance. In addition to being used for novel purposes, such as public toilets and gym pods, and the more traditional purposes, such as partitions, windows and doors for privacy, there are still many uses yet to be discovered.
