The Art of Accelerated Life Testing


ALT Testing Medical Device

Greetings from the Veteran's Corner, After two decades in the development trenches, one thing we have learned is that time is a luxury we can't afford to waste – and that's where Accelerated Life Testing (ALT) comes into play.


Let's take a moment to share a Quick perspective on this time-honoured technique that's as much an art as it is a science.



The Essence of ALT


In our whitepaper, "THE POWER OF ACCELERATED LIFE TESTING," we unpack ALT as our go-to strategy for aging devices at warp speed. It's our way of asking, "What will this device look like in 10 years?" without actually having to wait a decade. It's a bit like predicting which cars will become classics – a blend of experience, data, and a touch of engineer's intuition.

Cranking Up the Dial: A Calculated Move


Employing the Arrhenius model, we essentially turn up the heat – quite literally – to accelerate aging. Over the years, I've seen this model predict the future with uncanny accuracy, allowing us to ensure devices will last long after they leave the lab.


ALT in Practice: A Delicate Balance


It's a delicate dance, choosing just the right temperature to accelerate aging without degrading the device. It's not unlike finding the perfect roast for a coffee bean – too little and it's underwhelming, too much and you've gone too far. In our ALT studies, we're looking for that ideal condition that tells us how the device will behave in the long run without pushing it over the edge.


The Nitty-Gritty of ALT Testing


Now, the testing isn't just plug-and-play. We're methodical, taking into account factors like the Temperature coefficient and the specific attributes to monitor.

We've got to be precise, ensuring the accelerated conditions are rigorous yet within the material's tolerances. It's this attention to detail that ensures our predictions are as accurate as possible.


The Wisdom of Experience


With experience comes the wisdom to appreciate the nuances of ALT.


Yes, it's a projection, not a guarantee, but a well-conducted and validated ALT gives you as close a glimpse into the future as you can get in this industry. And when it comes to regulatory approval, it's this depth of understanding and thoroughness that helps usher our devices into the marketplace with confidence.


As we continue to innovate and push the boundaries of medical technology, ALT remains a critical tool in our kit. It's about more than just compliance or ticking boxes; it's about honoring the trust patients place in our work, ensuring the devices we develop today are still performing when they're needed most. Here's to the next twenty years of engineering excellence.
