A team of scientists from Carnegie Mellon University of America has found a new application for conductive paint. Practical experiments have shown that a small amount of such a substance is enough for any surface to have the properties of a touch panel. The Electrick system, which was developed by university professor Yang Zhang, works on the principle of electric field tomography. Using small electrodes that are installed around the perimeter of the surface painted with a conductive composition, Electrick gives the sensory properties of wood, plastic, gypsum, gelatin and clay. The panel launches a shunt effect, which creates the usual touch of the fingers. The voltage difference may be different. The scope of application for Electrick is very wide – from creating smartphone covers to improving the Smart Home system, where even walls can be endowed with a certain degree of intelligence. Specialists took into account the durability of the coating: so that the paint applied at this stage from an ordinary spray can It doesn’t peel or wash, it can be protected with a special coating with waterproof properties.
