More than just a blip: using radar to monitor vital signs
This is an excerpt of an article originally published on Waterloo News.
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.”
In the study, the radar unit was mounted to the ceiling over the bed of more than 50 volunteers as they slept normally in a model long-term care apartment.
The system, which collects and analyzes data from radar waves that are reflected back to the unit from the bodies of patients, achieved results over 90 per cent as accurate as standard hard-wired equipment.
“This is the first time radar has been used for heart sensing with this degree of accuracy and in such an uncontrolled environment,” said Mostafa Alizadeh, a research associate who led the study. “Our subjects slept unobstructed, in any position, for up to eight hours.”
Researchers are also exploring use of the technology to monitor activity levels and falls by residents of long-term care homes, and in hospitals for routine monitoring of heart and breathing rates of all kinds of patients.
Students compete in Data Open Championships

Out of 100 students competing at the Data Open Championship, 11 of them were from the University of Waterloo, making it the institution with the largest number of competitors to compete in the championship.
The top 24 teams from 23 datathon competitions held throughout the year at top universities across the US, Canada, Dublin, and Beijing pitched to a panel of top executive judges. Competitors had pre-submitted their reports on global infectious diseases. They used statistics and mathematical reasoning, and assessed complex, socially relevant problems and data sets. Presented by the hedge fund Citadel and trading firm Citadel Securities, the event took place at the New York Stock Exchange.
Congratulations to the 11 students for making it to the Championship:
- Priyank Jaini, PhD candidate, Computer Science
- Ankai Jie, undergraduate, Data Science
- Ryan Kinnear, Master’s candidate, Electrical & Computer Engineering
- Patrick Li, Master’s candidate, Statistics
- Neil Liu, undergraduate, Computer Science and Statistics
- Sai Praneeth, Master’s candidate, Applied Science, Mechanical and Mechatronics Engineering
- Kevin Wang, undergraduate, Mathematics, Computer Science and Optimization
- Richard Wi, undergraduate, Computer Science
- Alexandre Xiao, undergraduate, Mathematics, Combinatorics and Statistics
- Richard Zhang, undergraduate, Computer Science and Statistics
The University of Waterloo is hosting a two-day meeting of the local chapter of the Young Presidents Organization (YPO) on May 14 and 15. The YPO is an organization of chief executives from a broad range of industries under 40 years of age. More than 75 attendees will be on campus today and tomorrow. The meeting's events include a special CEO dinner at the Waterloo Region Museum tonight, with a pitch competition in Engineering 7, a "Why Waterloo?" panel featuring Murray Gamble, president of the C3 Group, Physics and Astronomy PhD student Kristine Boone, Jennifer Stanley, senior manager, research & development at OpenText and CEO of the Accelerator Centre Paul Salvini, and a campus tour taking place on Wednesday, May 15.
Conrad Grebel University College has announced that David Y. Neufeld will serve at Grebel as Visiting Assistant Professor of History for two years. Neufeld will also hold a research fellowship during his first year.
A Waterloo alumnus (BA '09), Neufeld comes to Grebel as a highly-regarded and accomplished teacher of European and world history from the University of Arizona, where he completed a master’s degree, followed by a doctorate in 2018. He is the author of Common Witness: A Story of Ministry Partnership between French and North American Mennonites, 1953-2003.
The Institute for Anabaptist Mennonite Studies (IAMS) at Grebel has also named Neufeld the 2019-20 J. Winfield Fretz Visiting Research Scholar in Mennonite Studies. He will spend time researching Anabaptist archival cultures and practices, as well as investigating a new archival turn in early modern European historiography that recasts archives as the products of historical processes, not neutral bodies.
Spring Welcome Week continues today with a Chopstick Challenge from 11:00 a.m. to 2:00 p.m. in the SLC's lower atrium and an ice cream social in the SLC's Multipurpose Room from 1:00 p.m. to 3:00 p.m.
