Smart glass, also known as switchable glass, is a type of glass that can change its properties, such as transparency and color, in response to electrical signals, light, or heat. This technology allows users to control the amount of light and heat entering a space, enhancing energy efficiency and privacy. Common applications of smart glass include windows in commercial buildings, vehicles, and even homes. It can be used in automotive industries for sunroofs and in architecture for modern facades, providing both aesthetic appeal and functional benefits.
