Wi-Fi Heart Rate Monitor could be reality in 5 years

The folks at university of Utah have come up with an innovative way to use a Wi-Fi hotspot for monitoring person’s breathing rate. They achieved this by rigging their system together by surrounding a hospital bed with 20 wireless transmitters on a 2.4GHz band. It then detects a person taking 0.4 to 0.2 breaths per minute based on only 30 seconds data, whereas most monitors round off to the nearest full breath-per-minute.

The researchers also tested the system for accuracy by means of a carbon dioxide monitor connected to the patient’s nostrils by tubes. The Wi-Fi monitoring system scores over traditional ones for reasons of comfort. But that still doesn’t compensate for certain hiccups like when the patient moves, the system will detect their movement in pace of their breathing rate. The system requires 13 wireless transmitters but with 19, its more accurate and can even monitor two people breathing at different rates. The folks at the Utah University expect that this technology could make their way into homes in the next 5 years.
