Qiyin Fang is the living embodiment of taking McMaster's engineering work into
the community. He isn't just outside the classroom. He's going right into other
people's houses.
The Canada Research Chair in Biophotonics is doing novel, eye-catching research
at a home in Westdale. Fang's team is equipping a two-storey century home with
sensors to better track patient activities.
The estate of Ernest Kay (Bsc '47, Chemistry and Biology, MA '49) donated the
house to McMaster University.
Once the monitoring methods are perfected, health care professionals will use
them to monitor older patients with chronic diseases, Fang says.
"We want to sense their physical activities and their physiological responses," says
Fang, who is an Engineering Physics associate professor. Sensors will track "which
room they're in, how their bodies react to temperature change, how often they use
the bathroom." Such data will be encrypted and owned by the patient.
Students will be the first test subjects in the house. Once Fang perfects the data
collection, he plans to outfit the home of an actual patient.
As lives get longer and the population
gets older, there's increasing demand
for comfortable implants that last as
long as we do. That's where Kathryn
Grandfield enters the picture.
Grandfield researches ways to make
better implants for hips, knees, dental
work, and other parts of the body. The
goal is to create better, easier and longer-lasting implants that better attach
to bone and make a more comfortable
life - and fewer surgeries - for the end
user.
"We want to provide an implant
that will last the lifetime of a patient,"
she says.
Grandfield primarily works with
titanium and titanium alloys. Titanium has a unique surface layer - an
oxide layer - that's biocompatible, she
says. And the material is enduring
enough to last 40 years. Its primary
downfall? It's stronger than bone, she
says, but right now "it's the best we
have."
