THE NEW DEVELOPMENT TURNED THE WALLS INTO A TOUCH PANEL

Developers, programmers from the University of Carnegie – Mellon, using electrically conductive paint and sensors, made from a conventional wall a touch panel. The new development will make it possible to locate the switches in any convenient place on the wall, control video games using gestures, and also inform, changing the lighting, about the boiling kettle.

Using the paint, the researchers applied electrodes to the surface of the walls . Thanks to them, the wall turns simultaneously into a touchpad for tracking the user’s touch and an electromagnetic sensor that monitors the operation of electronics and household appliances.

To reduce the cost of technology, the developers chose a water-based paint with nickel. As a result, the improvement required about $ 20 per 1 sq. Km. m.

Scientists used a conventional paint tape to apply two layers of diamond-shaped cells to the wall – during the study this form proved to be the most effective. After that, they removed the tape and connected the electrodes. The top was covered with ordinary latex paint to increase the strength and concealment of the system.
