Wireless system uses off the shelf components to monitor patients' breathing

Two years ago, University of Utah assistant professor of electrical engineering Neal Patwari demonstrated how radio signals could be used to “see” people through solid walls. Now, he is leading a team that is using that same technology to wirelessly monitor peoples’ breathing as they sleep. The system could be particularly useful for observing patients who are recovering from surgery, people with sleep apnea, and babies who are at risk of sudden infant death syndrome (SIDS). While respiration-monitoring systems do already exist, Patwari’s doesn’t require anything to be physically attached to the subject’s body, plus he claims that it should be cheaper.
