Glass Turns Opaque With Electricity

Here it s transparent and looks much like ordinary glass.

Glass turns opaque with electricity.

I saw a conference room with glass walls to seperate it from the cubes. When the power is turned off the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent. The transparent toilets turn frosted and opaque once locked.

Once you lock the door it triggers an electric current in the glass which turns frosted and opaque. Our technology allows for instant privacy of windows on demand with the flick of a switch or the turn of a dimmer and is the next generation in switchable privacy glass as well as electronic dimmable window. Introducing electric current with the flip of a switch turns the glass clear transparent. How do you make glass that turns opaque with electric current.

Reveal switchable privacy glass uses a low voltage electrical current to arrange liquid crystal molecules into a pattern that makes glass transparent when turned on. The glass developed at harvard can transition between transparent translucent and opaque with the application of an electric current. You can flip a switch and the glass walls go from transparent to opaque. Electrochromic glass changes color under electric control.

Turned off the lc molecules revert to a random pattern diffusing the light and causing the glass to become opaque. Scientists have developed a brand new type of electronic window that can switch from transparent to opaque and back again in under one minute. Even though similar dimmable glass already exists this invention relies on completely new technology and if it s successfully scaled up we could soon kiss goodbye to ugly window shades.

Smart glass electric switchable glass can be controlled manually or automatically automated control can be programmed to switch on or off during certain times of day or the system can be connected to light sensors to activate when a certain level of light is detected alternatively it can be programmed to activate with movement sensors remote controls and standard button switches. Retail applications include using the opaque state as an imagery glass rear projection screen surface on an exterior storefront. Smart tint switchable electric films are designed to variably adjust light between a transparent and an opaque state with ac power. When electricity is applied to the film via the wiring the liquid crystals align and the glass instantly becomes clear.
