Fadel Adib and his colleagues work in the Wireless Lab at MIT (under Dr. Robert Miller). Most of their research utilizes different radio waves and using their reflection to determine the presence of people in an indoor space. But this year, they produced a much higher resolution — Vital Radio — that records respiration rate and heart rate. This is a huge advance for the internet of things and smart homes. Look ma’ no wires!
"In this paper, we ask whether it’s possible for smart homes to monitor our vital signs remotely – i.e., without requiring any physical contact with our bodies.” People can just relax in their homes — note that the technology used here does require they sit or lie down — as they normally would and the system generates highly accurate respiration rate and heart rate data.
The system is highly accurate, with average accuracy rates over 98%. The researchers used consumer grade chest-strap heart rate monitors as their ‘ground truth’ measurements. And their system can measure these signals at a distance of almost 25 feet (8m)!
