Piezoelectric Effect Explained using a simple physical model

This video covers how crystals are used to create and receive high frequency sound. Apart from their use in small speakers, they are especially useful in their used of transducers for ultrasound imaging. Using a physical model we review the distortion of the crystal leads to a potential difference which can them be measured

The video is well done and the content is explained at a level easy enough for anyone to understand, but advanced enough to help you in the subject. He starts the subject at a level assuming a extremely elementary knowledge and slowly works up the ladder of knowledge. If you are wondering if this is the video to watch to help you understand the Piezoelectric effect, rest assured that you have found the right video.

I have seen around 7 to 8 videos on piezoelectric effect and your one explains it the best. ☺️

[mushyomens]

Holy crap! This is such a brilliant explanation. This channel is so underrated.

[wenwu-xu]

Brilliant!! Youtube has been my best teacher after school... Thanks for your great talk.

[gama]

Really helped my understanding of PiZeOLectRic crystals and the EM spectrum overall. Thank you again!!

[zainulabdien]

Best video on internet explaining piezoelectric effect..appreciated

[fatemehghezelbash]

This explanation is great. I couldn't understand Piezoelectric effect, but after watching this video I completely get it. Thank you very much indeed.

[ragin_cajuns]

It really makes sense...very nice explanation, sir.

[DaniiMarie]

Perfect! I love your teaching style!!! New sub❤

[darksun]

Can we just take a moment to appreciate the 2D moving model 👏🏾. Great explanation for a Highly interesting subject.

[bakanobasire]

ur explanation is great. you are indeed real teacher, how can i do research on piezoelectricity.

[Competitive_Antagonist]

This is the first compelling science video I was able to understand in a while. So it's not just the organised structure that gives it the piezoelectric effect, it's also the arangement of the charged particles.
I've heard that bone is a good piezoelectric material. I'm guessing that's how bone conduction works, as the sound distorts the structure of bone, converting it to electrical signals, then it reaches the 8th cranial nerve which get's processed by the brain as sound. I'm a bit foggy about the mechanics of sound hearing though. The ear seems like a very complicated piece of machinery.

It is remarkably simple but very useful and effective to learn about piezoelectric fundamentals

[akatsuki]

Very informative and simplified explanation!

[nipun_]

That is a really good explanation. Thank you so much ❤️❤️❤️

[ellispress]

Thankyou for explaining this topic as it looked so daunting when we were set it as work but now I understand it and am ready for my physics lesson

[desert.mantis]

Excellent explanation, Paul! Thank you. I Wish you were my college physics teacher back in the day...

[thecrazykartbyAJ]

Excellent video, thank you very much!! The explanation in 4:20 has opened my mind...
One question here please: I did not understand the reason in putting the negative charges in the upper or lower part of the crystal, and viceversa for the + charges, in the 9:37 minute...
Thank you!

Very good, will use for our students.

[ColoradoForestBeings]

Will applying weight on a quartz start a charge too?
