People with diabetes could be able to monitor their blood sugar without drawing blood using a system now being developed at the University of Waterloo.
In a recent study, researchers combined radar and artificial intelligence (AI) technologies to detect changes in glucose levels without the need for painful finger pricks several times a day.
“We want to sense blood inside the body without actually having to sample any fluid,” said George Shaker, an engineering professor who leads a large team working on the concept. "Our hope is this can be realized as a smartwatch to monitor glucose continuously."
The research involves collaboration with Google and German hardware company Infineon, which jointly developed a small radar device and sought input from select teams around the world on potential applications.
The system at Waterloo uses the radar device to send high-frequency radio waves into liquids containing various levels of glucose and receive radio waves that are reflected back to it.
