Glass Turns Opaque With Electricity

The glass developed at harvard can transition between transparent translucent and opaque with the application of an electric current.

Glass turns opaque with electricity.

When the power is turned off the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent. Retail applications include using the opaque state as an imagery glass rear projection screen surface on an exterior storefront. How do you make glass that turns opaque with electric current. I saw a conference room with glass walls to seperate it from the cubes.

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. Once you lock the door it triggers an electric current in the glass which turns frosted and opaque. Introducing electric current with the flip of a switch turns the glass clear transparent. A special film laminated between glass layers allows for instant privacy for any commercial or residential application.

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.

Is this a diy project possible. Scientists have developed a brand new type of electronic window that can switch from transparent to opaque and back again in under one minute. Turned off the lc molecules revert to a random pattern diffusing the light and causing the glass to become opaque. Here it s transparent and looks much like ordinary glass.

You can flip a switch and the glass walls go from transparent to opaque. Electrochromic glass changes color under electric control. When electricity is applied to the film via the wiring the liquid crystals align and the glass instantly becomes clear. The transparent toilets turn frosted and opaque once locked.
