Paint job transforms walls into sensors, interactive surfaces

Paint job transforms walls into sensors, interactive surfaces Walls are what they are -- big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used. Researchers found that they could transform dumb walls into smart walls at relatively low cost using simple tools and techniques, such as a paint roller. https://ift.tt/eA8V8J
