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. Retail applications include using the opaque state as an imagery glass rear projection screen surface on an exterior storefront. 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. You can flip a switch and the glass walls go from transparent to opaque.

The glass developed at harvard can transition between transparent translucent and opaque with the application of an electric current. 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. Michelle starr march 14 2016 10 53 p m. Apply a small voltage and it turns opaque blueish and dark.

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.

When the power is turned off the liquid crystals return to their normal scattered positions rendering the glass an opaque translucent.

Once you lock the door it triggers an electric current in the glass which turns frosted and 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. Electrochromic glass changes color under electric control. 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.

When electricity is applied to the film via the wiring the liquid crystals align and the glass instantly becomes clear. Turned off the lc molecules revert to a random pattern diffusing the light and causing the glass to become opaque. The transparent toilets turn frosted and opaque once locked. Smart tint switchable electric films are designed to variably adjust light between a transparent and an opaque state with ac power.
