A radar system developed at the University of Waterloo can wirelessly monitor the vital signs of patients, eliminating the need to hook them up to any machines.
A radar system developed at the University of Waterloo can wirelessly monitor the vital signs of patients, eliminating the need to hook them up to any machines.
Housed in a device smaller than a cellphone, the new technology records heart and breathing rates using sensitive radar waves that are analyzed by sophisticated algorithms embedded in an onboard digital signal processing unit.
Researchers developed the system to monitor sleep apnea patients by detecting subtle chest movements instead of connecting them to equipment in labs via numerous cumbersome wires.
“We take the whole complex process and make it completely wireless,” said George Shaker, an engineering professor at Waterloo. “And instead of a clinic, it could be done in the comfort of your own bed and run daily for continuous monitoring.”
