When I was 17, I worked at a fastener company in Mississauga, repackaging car parts called spacers—or as we called them, "Jutras." My job wasn’t glamorous: help the lead engineer fine-tune a machine he built. But this machine was fascinating. It vibrated at high frequencies to move spacers through pathways where sensors checked for specifications. By the end of this 10-foot-long contraption, the spacers were either deemed good or rejected.
I didn’t know it then, but that summer job was the spark that ignited my lifelong curiosity for technology and engineering. The experience of tweaking that machine, getting my hands dirty, and solving real-world problems taught me the power of innovation and persistence. I saw firsthand how something as simple as vibration could transform an industry.
Fast forward to today, and the challenges of vibration in engineering remain just as important—and just as wicked. Vibration disrupts machines, causes wear and tear, and impacts precision. It’s a problem that has persisted for decades, yet one that’s still waiting for elegant solutions.
Enter Shape Memory Alloys (SMAs) and Quantum Computing, two technologies that could redefine how we tackle vibration in engineering.
The Wicked Problem of Vibration
Vibration is more than an annoyance; it’s a silent saboteur. In cars, it causes parts to wear out prematurely. In buildings and bridges, it creates structural instability. In precision devices, it disrupts accuracy.
The challenge is that vibration isn’t static—it changes based on frequency, load, and environmental factors. That complexity makes traditional solutions, like dampers or springs, clunky and inefficient. This is where SMAs shine but imagine SMAs and Quantum working together!
SMAs + Quantum: The Perfect Pair for Solving Vibration Problems
Shape Memory Alloys (SMAs) are materials that "remember" their original shape and adapt to forces like vibration. Pairing them with quantum computing creates groundbreaking possibilities to predict, control, and optimize vibrations in real time. Here’s the magic in three steps:
Dynamic Adaptation (SMA): SMAs adjust their stiffness and shape in response to vibrations, absorbing energy to transform mechanical chaos into stability.
Predictive Insights (Quantum Computing): Quantum systems analyze vibration patterns on an unprecedented scale, modeling complex scenarios and delivering optimal solutions almost instantly.
Intelligent Integration: Combining SMAs and quantum creates adaptive, energy-efficient systems—like bridges that not only endure earthquakes but "learn" to counteract them in real time.
Canadians Leading the Way!
In Canada, several companies are at the forefront of SMA technology:
Smarter Alloys: Based in Waterloo, Ontario, Smarter Alloys is pioneering advancements in smart materials. Their Multiple Memory Material™ technology enhances the capabilities of SMAs, enabling their integration into diverse products and devices. Their innovations are applied across various industries, including medical devices and automotive actuators.
Kinitics Automation Limited: Located in Vancouver, British Columbia, Kinitics specializes in developing actuators and pumps that leverage SMA technology. Their products offer precise control and efficiency, making them suitable for applications in sectors like oil and gas, aerospace, and advanced manufacturing. Notably, NGIF Cleantech Ventures has invested in Kinitics to scale up their disruptive SMA technology.
From Warehouse Floors to Cutting-Edge Innovation
That warehouse job feels like a lifetime ago, but its lessons echo today. The power of vibration—both as a problem and a tool—continues to drive my fascination with technology. Engineering is about embracing complexity, learning from the past, and imagining better futures.
As Steve Jobs famously said, “You can’t connect the dots looking forward; you can only connect them looking backward.” That vibrating machine was the first dot on my journey—a reminder that curiosity and hands-on problem-solving can lead to breakthroughs we never imagined.
My guess: SMAs and Quantum will solve some of the most stubborn engineering challenges of our time—like vibration control, energy efficiency, and adaptive materials. These technologies have the potential to transform industries, from building safer infrastructure to creating smarter transportation systems and even stabilizing sensitive medical devices. Together, they could redefine what’s possible in precision engineering and dynamic problem-solving.
