The world wants to be connected to the internet at all times, and as a result we're bombarded by Wi-Fi almost everywhere we go. Yasamin Mostofi, Associate Professor in the Department of Electrical & Computer Engineering at UC Santa Barbara, wanted to know can we use them not just for connectivity, but for sensing?
Using nothing more than a Wi-Fi card and a receiver, Mostofi has shown that it's possible to see through walls - useful for search and rescue - as well as sense the number and location of people in a building, which could transform smart lighting and HVAC technology.
