Diagram of Wireless Links to Monitor Breathing (IMAGE)
Caption
This diagram shows how a network of 20 wireless transceivers send radio waves crisscrossing a person on a bed. The transceivers or "nodes" connected by dashed lines indicate radio signal links that detected breathing. University of Utah engineers are developing wireless networks as a new kind of breathing monitor named BreathTaking, and hope it can be used to allow more comfortable monitoring of breathing by people who have undergone surgery, adults with sleep apnea and perhaps babies at risk of sudden infant death syndrome.
