About the same size as existing glucometers, the rectangular device works by sending radio waves through the skin and into blood vessels when users place the tip of their finger on a touchpad.

“Our safe, reusable, pain-free device would eliminate the need for implanted sensors, patches or devices that use chemical reactions or fluid transfer through the skin,” Ala Eldin Omer, an engineering PhD student who led the project said

Professor Safieddin (Ali) Safavi-Naeini said the science at the heart of the diabetes device potentially has several additional applications.

Two researchers at Waterloo Engineering have been awarded more than $7 million in provincial funding to support their work.

The antenna was designed by a large academic team from the University of Waterloo's CIARS in close collaboration with industrial experts from COM DEV International (now Honeywell Canada) and space qualification testing specialists at the Canadian Space Agency's (CSA's) David Florida Laboratory (DFL).
