Electrochromic glass maintains visibility in its darkened state and thus preserves visual contact with the outside environment. Recent advances in electrochromic materials pertaining to transition-metal hydride electrochromics have led to the development of reflective hydrides, which become reflective rather than absorbing, and thus switch ...
An electrochromic device (ECD) controls optical properties such as optical transmission, absorption, reflectance and/or emittance in a continual but reversible manner on application of voltage (electrochromism). This property enables an ECD to be used for applications like smart glass, electrochromic mirrors, and electrochromic display devices.
Electrochromic glass installed in buildings. Several electrochromic devices have been developed. Electrochromism is commonly used in the production of electrochromic windows or "smart glass", [3] [1] and more recently electrochromic displays on paper substrate as anti-counterfeiting systems integrated into packaging. [27]
These include electrochromic materials, which change their colour or opacity on the application of a voltage (e.g., liquid crystal displays), thermochromic materials change in colour depending on their temperature, and photochromic materials, which change colour in response to light—for example, light-sensitive sunglasses that darken when ...
A photochromic eyeglass lens, part of the lens darkened after exposure to sunlight while the other part remained covered. A photochromic lens is an optical lens that darkens on exposure to light of sufficiently high frequency, most commonly ultraviolet (UV) radiation.
The company's product, View Dynamic Glass, features an electrochromic (EC) coating composed of multiple layers of ceramic metal oxide with a thickness of 1 micron. [18] Low voltage wiring is added so the tint of the glass can be controlled through an app or centralized software system in response to weather or interior temperature.
