The SHOCK Show #7: How Can You Reduce the Variability of Piezoelectric Materials?
Welcome to The SHOCK Show #7. In this episode, I talk about variability in piezoelectric material properties and how to reduce them. Inspired from my experience ordering drinks at Starbucks, I describe an effective method for reducing variability and thus increasing yield.

Yes, one of the largest problems in piezoelectric transducers are the piezoelectric transducers
Piezoelectric materials of the same type have a VERY significant amount of variability. Some manufacturers cite +/-20% tolerance. Now, there are several ways to ensure that this huge swing in properties will still result in successful minimally varying products. This is the real magic of ultrasonic transducer design, analysis and production
What does piezo variability have to do with Starbucks?
Everything, everything, EVERYTHING! When I go to Starbucks, I often get the Vanilla Sweet Cream Cold Brew. Many times, they put too much cream or too little cream. When I ask for a remake when I get too much cream, my next drink gets too little cream. Same story when I ask for a remake for a drink with too much cream.
Therefore, I get another cup and mix the two drinks together. I am one happy camper with a huge drink just the way I like it!
Okay.. I'll ask again, what does this have to do with Starbucks?
A key way to reduce variability in piezoelectric devices is to pair elements with low electromechanical coupling with those with high mechanical coupling. This reduces the variability significantly, more than half! So, just like mixing two drinks on opposite ends of the "cream-spectrum", you can mix piezo element at opposite ends of the property spectrum. THIS IS A HUGE DEAL!
