Prof develops wearable, non-invasive health monitor
University of Waterloo engineers have invented a powerful antenna small enough to fit in a ring and capable of transmitting critical medical data to healthcare workers and individual patients.
Lead researcher Dr. Omar Ramahi, a professor at the Department of Electrical and Computer Engineering, worked with Rania Rabhi, a visiting scholar from Tunisia, to build an antenna that is small enough to be worn like a piece of jewelry and powerful enough to safely send medical-related information to smartphones or a health clinic over long distances through airwaves.
