It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini Bharathula explains how piezoelectric materials turn mechanical stress, like pressure, sound waves and other vibrations into electricity, and vice versa.

Those hippies were right. Those crystals vibrate with energy!!!
John Smith lol I have crystals for my chakras
They also know of energies beyond eletricity.
😂
Spiritual and scientific things are actually the same but different like fraternal twins
@@johnathansmith713 Mhm! Spirituality and Technology are def the same, just retold in different stories.
I used to dig for quartz crystals in Arkansas, and one time had a pair of "pounders" which were too damaged or too cloudy to be worth much so I used this pair to rub together at night to get them to glow! Great fun was had by all.
So you rubbed two crystals and they started to glow with electricity? Thats neat
Are you serious? That's possible?
That sounds sick
Unpolished crystals are powerful

Electrocuted by lingerie. Your contribution to science will be remembered. RIP.
That's why women are so powerfull
matroosoft wow sounds sexist
Guys don't wear lingerie so the joke is not sexist.
gay men do
at least my neighbor does
Now I can safely say that this is the best animation I've seen on this show since the begging, I mean God damn this is better than most of the shows on TV. Great work, keep it up.

This is the part of my education that was wiped out from seizure activity. So many questions that have been in my mind for a decades are being answered. Thank you! Millions of ideas are springing from this right now i have to research more.
I am currently in the midst of preparing my M.Tech thesis in harvesting piezoelectricity and this video was an amazing watch!! It so vividly explains the phenomenon with utmost clarity and simplicity. Loved it! :D

Could I possibly access your thesis? I am doing a project that involves trying to incorporate piezoelectric generators into a rocket during flight. I am trying to find a way to increase its capabilities but haven’t found much.
This is a fantastic animation style.
Austin Anderson I am interested to know who did this animation ?😭
It's the first time I came to say that about TedEx talks. It's amazingly animated!
In the description is says Karrot Animation did it.
yeah man..already checked their website. They have made pretty awesome stuff.

this is one of the most BEAUTIFULLY animated episodes yet!! hats off, TedEd!!
I remember hearing that these are also used for more powerful microscopes. When they have to focus in on an object in the nanoscale, without breaking or dulling the tiny fragile equipment(specifically the cantilever), they need to "inch" one way or another in extremely small units. They run current through piezoelectric materials, which then move the probe part of the microscope up/down or sideways just slightly.
I'm not very sure about what I'm saying, does anyone know enough to explain it properly?
No I don't, but I'm replying in case someone explain it :D
Well, fuck. Not even I knew that. Thanks for mentioning that, mate.
Mira Jain replying to learn more about this
i dont realy know anything about this but it does make sense becuse in the video they say that when you pass a current in this typy of materail it changes its size.
soo if you can make a small current that will allow you to make small changes to the size and that can move the microscop a littile.
i guss...
When a voltage (electric force) is applied to both sides of the crystal, the charged particles that make up the crystal redistribute themselves to align with the electric field (so negative charges move towards the positive side and positive charges move towards the negative side). Depending on the polarity (direction) of this voltage, the crystal will either compress, or expand, this is basically what is shown at 2:45, but in reverse. This small shift in position can be enough to move an object into focus on a microscope.
They also use this technique in manufacturing to produce very small objects with precision, such as the billions of transistors inside a computer chip. In this case, they will use many crystals to get the exact positioning required.
This was an absolute delight. Thank you, all involved! I do wish that learning too, all manner of signalling molecules, carried with it just such a soundtrack...

this was a beautifully animated and informational video, I learned so much from this short video!
"Welcome back to my laboratory, where safety is number one priority" *puts on cool shades*
The graphics are amazing! Holy crap, keep those animations up!!
I showed my biology teacher your channel and now he shows us all your newest videos.
animation is perfect. thank yoh for so talented person
Thanks for the video, y'all did a great job! I love the visuals
Show de bola essa explicação sobre os materiais piezoelétricos.
OMG! The animation *has upgraded*. So cool!
👏👏👏👏👏👏
Very well-done video! Precisely what I needed; thank you!
the animation was awesome in this video
Such an awesome explanation!!! Very interesting too
Fascinating. I can't believe this actually existed for so long
Excellent explanation..... It will be used to my seminar presentation on piezoelectric materials
This is awesome! Thanks TED-ED !
beautiful animation as always
Amazing animation and flow of information.
This video was sooo amazing and unique!! I loved it!
That was some amazing animation.....
Very cool! I love learning about things like this. Physics is my fav subject
Amazing animation ! 🔥
FINALLY - I learned something today! Thanks always, Ted-Ed!
Hi😁
Thank you Scott
This animation is top notch!
If, as this video suggests, the quartz produces a current when constant pressure is applied to it, what factor is stopping us from just stacking a bunch of weight on the crystal and producing infinite energy...?

Thank you.This video is useful in many ways.
Could you do a video on what exactly electricity is as well. I've watched a couple videos on electricity, like this one, but I don't know what it truly is or how it behaves.
BTW those too scientists are my favourites when it comes to TED-Ed animations.
I really want to look more into this as an energy source.
This was well done. I really enjoyed it.
Awesome animation, nicely explained. I also wanted to know that for a while but noone knew and i forgot about it.

DuckJoan 04 your lucky 😥
Very useful ill suggest to be next video also by this based on by diff electricity topic
Great Ashwini bharathula...and karrot.
animation is top notch
Ted ed is just ridiculously awesome. Can you guys do a video on more basic things. Like the simple electromagnetic effect/ Electromagnetic waves? Especially relative to what is the electric field/magnetic field changing?, How can there be no time lag between these two fields?.-Thanks ted ed

This is so cool! I loaf this channel
This is so fascinating !
Your animations are not only interesting and well done but also keep some (medical) students from failing. Thank you!
That was an amazing video ... my mind was blown
Oh man, the last part would be a huge benefit!
So that's why Dr Robotnik always wanted the chaos emeralds!!!
I only knew about Piezoelectric crystals because they're used in the pickup systems for Acoustic Guitars, allowing them to be amplified like an Electric Guitar without a Microphone :D
Nice topic and great presentation 👏👏👏
this one is already changed the world.
awesome channel
Piezoelectric pickups are often used on acoustic instruments, particularly guitars, and I've always wondered how they work. This was a great explanation. I've also heard a few different pronunciations over the years that I've been playing, so it's nice to finally know which one is correct.
Also, iirc, most computers use a piezoelectric crystal (called a clock crystal) to generate the clock signal that keeps all their components in sync with each other.
One of the few things I already knew!! YAY!!
very well explained.. thank you
Great presentation
this is just freaking amazing
i like these types of ted ed videos
but how does the electrical current effect the crystals on molecule scale?
they may change shape overtime.
This video needs more views!
I can see a pretty good portable power source powered by something like this; Modify a crank clamp (Those tools you turn the crank and it squeezes what's between its two plates) so it has conductive ends (The parts that push on the object) and have wires going from the clamps to an output, secure a properly cut Quartz Crystal in between so compressing it will create charges on the clamp plates, and that output can power something. Also, make sure you put on insulators where appropriate to keep the user from getting shocked by accident. It's not too expensive, capable of being carried like a water bottle, and can probably work a light or motor for a good long while. (I came up with this before today, 8:40 a.m. on 7-17-2017) The low current might be a problem...
Well, so squeeze the energy out from space using the dynamic Casmir effect using these....
This should be shown in schools
Great lecture hats off
does the thickness of the crystal affect the voltage, or just the area of the two opposing surfaces?
Very nice explanation 👌👌👍👍
Excellent, thank you
can you make one on pyroelectricity as well?
These animations 😍😍
Thank you that was very helpful.
That was really great!
This is an awesome video.
why I never heard of this awesome discovery ? damn
I'm curious could you use stuff like this to power something in an area with a higher pressure like underwater or lower pressure like space?
Superb !!!!! Now words to describe
so it need an alternating movement to the Cristal or just putting constant pressure produce electricity ?
Incredible!
amazing video !
Question: is it possible to use that as a source of energy using gravity and just the weight of the material itself?
Lets say there's one of those crystals in Jupiter, for instance. Letting it on the ground or on a table would make some difference in voltage between the top and the bottom of the crystal, even if just a little?
I'm actually learning about this right now in my intelligent structure class
Piezo discs are inside of those electronic drum pads. The harder you hit the drum pad, the louder the controller plays the drum sound.
Am I going to recommend these to my science teacher, yes...
I wonder hower how efficient it is at converting movement into electricity, could a large crystal hooked up to a piston like structure were rotation causes an object to be repeatedly compress and stretch the crystal be more efficient than the old electric motor in reverse trick?
What I'm missing here is a mention of how efficient this technology is... Always with the missing information.
^
Exactly,
The video is 5 minutes long! Should they explain everything?
So can we use it in high pressure enviroments to generate electricity? For exemple in the deep oceans or other planets?
What an interesting video!
this is soo amazing .
Love you Ted ed
could you make a machine that runs forever off of this I'm thinking about the sound example and if you have a constant sound that creates electricity from the crystals it could go on forever and since sound is free flowing you could have multiple crystals getting energy from just one sound source so you can continue to power the sound source and maybe have some left over energy?
How does a used quartz crystal replenish it's Electrons after being compressed, are new ones made somehow or are Electrons brought in from the crystal's surrounds.
Smarter Every Day has a really cool video where you can see the sparks in slo-mo when Destin crushes some Life Savers
This is so interesting !!
the sidewalk charging would be revolutionary and super useful
Yup..got it
Great video
totally awesome
Amazing visuals!
:D
This is so cool!
