New grads make top three in Dyson invention contest

Two recent Waterloo Engineering graduates were named national finalists in a prestigious design contest this week for an idea that began taking shape in a first-year class.

Anneke van Heuven (BASc ’21) and Elias Trouyet (BASc ’21) were just starting the nanotechnology engineering program when they learned that the chemicals in most existing flame retardant materials can cause long-term health effects including cancer.

Better masks needed to stop virus spread

The findings of a new study highlight a need for widespread use of better face masks and the importance of good ventilation to mitigate the spread of COVID-19 indoors.

Waterloo mechanical engineering researchers performed experiments using a mannequin to simulate a seated person breathing in a large room.

The studies showed a significant buildup over time of aerosol droplets – exhaled droplets so tiny they remain suspended and travel through the air – despite the use of common cloth and blue surgical masks.

PhD student's app tracks COVID vaccine doses

A systems design engineering doctoral candidate has used his biomedical engineering background to develop technology to accurately track COVID-19 vaccine doses at clinics. 

Ryan Tennant, who holds undergraduate and master's degrees in systems design engineering from Waterloo, designed an app to "help alleviate the stress of end-of-day doses – to ensure that there are fewer or no doses that go unused.”
