Smart Materials: Introduction to Piezoelectricity lecture by Elizabeth Vanderhoef

[@ranjithramadurai7172]

Nice Lecture.. However in the introduction to piezoelectric material slide the symbol of Zirconium is given as Zn.. which is actually Zr.

Very nice presentation, and the sound quality is perfect. Thanks a lot for this very useful video. Please keep posting videos, you are gifted for that (I really mean it).

nice presentation. however, can you explain how to Fabricate and processing the piezoelectric ceramic ?

[@AnonymousRootz]

Hey any idea where i can that PWP presentation of yours? Would be really helpful in a near future, because im introducing my class mates into new and viable options by using piezo elements

[@kammularamgopal]

a very good lecture about piezo electricity

[@AL1977CHE]

Zirconium is Zr not Zn (Zinc)

so, we can convert sound energy into electrical energy...

[@adammizban3553]

We can convert any form of energy into any other forms of energy! We've been able to turn sound waves into electricity, ever since the invention of the microphone!

very very helpful

Some bad mistakes in this. Misspellings and wrong element symbols. Piezein Zr

[@64etto]

Di recente ho fatto domanda al istituti di ricerca perchè non utilizzare i cristalli piezoelettrici o piezomeccanici per regolare con una piccola tensione le diottrie le messa a fuoco e la struttura di prismi ottici, visto che per regolare la collimazione o messa a fuoco della lente di plastica del laser del lettore cd rom, cd audio, dvd, utilizza un solenoide "quanta energia risparmia un cristallo piezoelettrico da un solenoide"?

ma'am can u share the ppt

Greatttttttttttttt

Zr ,,,Kahan milega

But, does Piezoelectricity taste like a pie?

[@abdullahsaad8825]

Very Beautiful !!! I mean the girl

[@kenrutherford1109]

Nice comment!

[@nassimback]

is this chemistry ? physics ? or electronics ?

[@lamyaebenhammou8194]

These is Science of materials. when we study the proprietary of all materials.
