When installing insulated glass for the bedroom, we are faced with such a choice:
Ordinary glass: It can make the indoor light abundant and the sun bright, but it also exposes the privacy in your life to the fullest.
Tinted glass (or frosted glass) : Although it leaves you with enough personal space, it has the defect of being opaque.
Ultimately, people often have no choice but to compromise: drawing a thick curtain behind the window pane!
Perhaps soon, this problem that gives you a headache will no longer exist!
A type of glass that American scientists are developing, which uses electrically controlled materials to adjust the light transmittance, will solve this difficult problem easily.
At a recent exhibition, scientists demonstrated the "humanistic care" of this new type of glass to us: A shiny ordinary piece of glass, after simple remote control adjustment, turned into opaque frosted glass in an instant.
Why can this kind of glass change from transparent to opaque?
The mystery lies in that this kind of glass is composed of two ordinary pieces of glass with a layer of electrified liquid crystal molecular film added between them.
When no current passes through the film, the liquid crystal molecules are arranged randomly in the free state, the incident light is scattered, and the glass darkens. When an electric current is applied and a magnetic field is applied, the liquid crystal molecules are arranged vertically, allowing incident light to pass through, and the glass becomes transparent.
That is to say, people only need to adjust the light transmittance of the glass by adjusting the voltage level, thereby replacing the opening and closing of the curtains.
Glass has undergone thousands of years of development, from the "crystal clear and glittering things" first discovered by the Phoenicians to the simple glassware made by the ancient Egyptians, then to rare wearing accessories and expensive court tributes, and up to today's ordinary daily utensils, important materials in the field of science and technology, and precious artistic masterpieces, as well as those "intelligent glasses with spiritual energy". Its types and quantities have shown an exponential growth, and its quality has undergone earth-shaking changes. The development history of glass reflects people's yearning for a more convenient life and extends people's boundless wisdom and extraordinary talents. And smart readers, have you gained any inspiration from these "magical glasses"? Perhaps one day, in your hands, a more intelligent and magical piece of glass will be born!
