Game-changing breakthroughs are nothing new for Waterloo Engineering. Right now, students, faculty members and alumni are revolutionizing hardware development, tapping into unlimited sources of clean energy, working to save healthcare dollars spent on heart disease treatment and much more.
Take Multiple Memory Material™. Like many innovations, it came about through unintended consequences. As a doctoral candidate, Ibraheem Khan (MASc ’07, PhD ’10, Mechanical) working with Norman Zhou, a Waterloo mechanical and mechatronics engineering professor, realized the lasers and electron beams used as welding tools were changing the properties of the materials he was joining.
However, the properties they gained were highly intriguing: the ability to remember more than one shape and apply specific amounts of force in specific locations. Inspired by Waterloo’s inventor-owned intellectual property policy, Khan and Zhou launched Smarter Alloys to commercialize the discovery.
One of the company’s latest ventures is developing wires for orthodontic braces that promise to cut treatment time dramatically. Anyone who has worn braces knows just how long the process can be. Because different teeth require different degrees of correction, dentists swap brace wires every few months, increasing or decreasing the stiffness to target different teeth. Smarter Alloys’ SmartArch™ wires change all that, providing a single wire that applies exactly the right force to each tooth at the same time.
The biomechanically optimized archwire was launched to great enthusiasm at May 2015’s annual session of the American Association of Orthodontists in San Francisco. SmartArch has also caught the attention of someone closer to home — Khan’s wife. The newly minted dentist is interested in bringing the technology to the Guelph dental clinic she recently joined.
