Learn Piezo provides the most comprehensive online video tutorials on piezoelectric materials and their applications. We have compiled over 30 hours of videos in over 15 separate lessons.
Understanding piezoelectric materials devices is challenging because it requires knowledge of material science, electrical, mechanical, and software/firmware engineering disciplines. Thankfully, I have setup the "Learn Piezo" lecture series where I start from foundational concepts such as electrical charge and strain and build up all the way to energy harvesting applications and ultrasonic transducers.
