Wireless Network Monitors Breathing (IMAGE) University of Utah Caption University of Utah electrical engineer Neal Patwari reclines in a hospital bed surrounded by wireless transceivers like those used to connect home computer networks. In a new study, Patwari and colleagues show how crisscrossing radio signals from a wireless network can detect breathing -- a possible new, noninvasive way of monitoring postsurgical patients, adults with sleep apnea and babies at risk of sudden infant death syndrome.
