Radar â€” the technology that tracks enemy bombers and hurricanes â€” is now being employed to detect another danger: when babies stop breathing.
In a high-tech twist on the remote devices that allow parents to listen to or watch their baby from a far, University of Florida engineering researchers have built a prototype baby monitor that focuses on a babyâ€™s breathing.
If his or her chest stops moving, the crib-mounted monitor detects the problem and sends an alarm to a portable unit kept by the parents.
â€œItâ€™s a step beyond just watching the baby through a video link or hearing it cry,â€ said Jenshan Lin, a UF professor of electrical and computer engineering and the principal investigator of the Doppler radar technology used in the monitor.
Parents buy millions of baby monitors each year in the U.S., but most transmit only sounds or video images of the baby â€” both useful, but only if a parent is listening or watching.
Some recently available monitors also monitor babiesâ€™ movements and breathing, but Lin said he is not aware of any on the market that use wireless technology.
