Glass Turns Opaque With Electricity

Smart tint switchable electric films are designed to variably adjust light between a transparent and an opaque state with ac power.

Glass turns opaque with electricity.

A special film laminated between glass layers allows for instant privacy for any commercial or residential application. 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. 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. Electrochromic glass changes color under electric control.

The glass developed at harvard can transition between transparent translucent and opaque with the application of an electric current. 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. Scientists have developed a brand new type of electronic window that can switch from transparent to opaque and back again in under one minute. Introducing electric current with the flip of a switch turns the glass clear transparent.

Once you lock the door it triggers an electric current in the glass which turns frosted and opaque. You can flip a switch and the glass walls go from transparent to opaque. How do you make glass that turns opaque with electric current. 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.

Apply a small voltage and it turns opaque blueish and dark. Retail applications include using the opaque state as an imagery glass rear projection screen surface on an exterior storefront. Here it s transparent and looks much like ordinary glass. 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.
