Smart Glass
Smart glass or switchable smart privacy glass (also called smart window or switchable window in those applications) is a glass or glazing whose light transmission properties are altered when voltage, light, or heat is applied. In general, the glass changes from transparent to translucent and vice versa, changing from letting light pass through to blocking some (or all) wavelengths of light and vice versa. Smart glass can be constructed by lamination with a smart film or switchable film, often using either glass, acrylic, or polycarbonate laminates.
