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.
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.
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.
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?
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 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.
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...
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...?
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
I feel like this energy source is under appreciated charging a phone walking isn't a wow moment considering the practicality of energy through crystals an sounds is a wow moment
For all you know this is the missing element to infinite energy I mean it's powered by noise an motion for all you know there's a crystal better than quartz that could create large amounts of energy
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...
You wouldn't have a cable in the ground, it could be used on roads to generate some charge to be used in sockets that you would connect something to, or through an alternative solution. But the energy generated from your shoe wouldn't be enough to power your phone anyway, it would be insignificant.
That way it gives sense and I have to agree with you that the shoe alone wouldn't have enouth power. But the way Chris presented it it seemed like "having a cable sticked into the ground while walking would be better".
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
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.
Interestingly enough, there is almost no energy in compressing a solid since energy is defined as KG m^2/s^2. So using PZT-5A as an example. If you have a 37 mm diameter, 5 mm thick piece of PZT and you press on it with 9.81 N of force or the equivalent of setting a 1 kg weight on the PZT. The PZT will compress 164 picometers so the energy expended compressing the PZT-5A is 9.81 N * 164 pM which is around 1.648 nJ. Now you use the D33 value and the G33 value and the pressure in pascals to determine the power generated. They cruely list the values in C*m^2/N which is c / (N/M^2) and N/M^2 is a pascal. But for PZT the G33 is 326 pC/PA and 2.4 mV/Pa. pressure is force / surface area. So the PZT-5A experiences 2281 pascals of pressure. So the PZT-5A will make 24.35 mJ of energy. The opposite is true when using the PZT-5A as a prime mover. It's like a striling engine. If you use a striling engine to move heat energy aroun, it's a heat pump and has a COP > 1 but if you use it as a heat driven engine, it has a COP that is equal to 1/COP when you are using it as a heat pump. Perfect inversion of energy. It's also why stirling engines are not free energy.
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.
This misinformation is unacceptable. The voltage generated may be large, but the current is incredibly tiny. When the clapping to trigger the lights example is used, seperate machinery needs to detect the charge difference and turn on the lights (powered by mains). The amount of footsteps needed to power station gates or a dance club is ginormous and completely impractical. A child may watch this video and take in without questioning these false examples.
Although I agree with that, TED was simply giving an example. It would require an immaculate amount of Piezoelectric Energy to run street lights. An alternative could be that the Piezoelectric Energy helps charge the street lights, similar to a hybrid car.
Now that I know it would cost so much to produce the material composed of crystals, I can shelve the idea. I could never save enough energy to pay back the production cost.
So WHILE a crystal is being compressed, it generates a direct current in one direction. Once the compression stops, no current is generated. But, WHILE a compressed crystal is being released (decompressed), it generates a direct current in the opposite direction. Once the decompression stops, no current is generated. Is that right, or is there more to it?
The last name Curie has a reputation for science so I wouldn’t be surprised if a Curie suddenly discovered that planets can fly in the 11th dimension or something.
Just take two agates and grind them together in your hand in total darkness and watch the sparks. That's how the fire breathing leviathan made fire when he belched methane gas from his tummy and chewed rocks having quartz at the same time. The sparks from crunching on rocks like chickens do set the methane gas from his stomach on fire. Animals that lay eggs, eat pebbles to make shells for their eggs. Man walked with dinos. Anyway the sparks are neat.
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.
This video was pretty informative about piezoelectric materials, It's a bummer that I already knew about this stuff for a long time now which kinda made the video less exciting. I guess the only thing I learned is the atomic structure symmetry.
The first practical application lol , um what about the great pyramid as only one example? Ancient civilizations all over the world new this and applied it practically, just look at the high quartz content in the materials used in construction no coincidence

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

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.

I really want to look more into this as an energy source.
Your animations are not only interesting and well done but also keep some (medical) students from failing. Thank you!
FINALLY - I learned something today! Thanks always, Ted-Ed!
Hi😁

instead of making roads out of them why not make shoes???
Would you like to walk everywhere with cords attached to your shoes?
So having a cable sticked into the ground while walking is better?
*stuck
You wouldn't have a cable in the ground, it could be used on roads to generate some charge to be used in sockets that you would connect something to, or through an alternative solution. But the energy generated from your shoe wouldn't be enough to power your phone anyway, it would be insignificant.

Oh man, the last part would be a huge benefit!
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?
How come people dislike such a cool topic?
animation is perfect. thank yoh for so talented person
Piezo discs are inside of those electronic drum pads. The harder you hit the drum pad, the louder the controller plays the drum sound.
the sidewalk charging would be revolutionary and super useful

this was a beautifully animated and informational video, I learned so much from this short video!
If you use electromagnetic fields to "squeeze" the crystal instead of doing it physically the energy output would be exponentially greater.
Is this why people "charge" there crystals using the sun?
Well, so squeeze the energy out from space using the dynamic Casmir effect using these....
Show de bola essa explicação sobre os materiais piezoelétricos.

also the claim that unit cells on some crystalline structures lack o a center of symetry es completely wrong, they all do
And they show crystals generating continuously, when it's only on pressure change.
Unacceptable indeed for educational stuff.
DAMN, TED. How many other videos may be filled with misinformation?
Although I agree with that, TED was simply giving an example. It would require an immaculate amount of Piezoelectric Energy to run street lights. An alternative could be that the Piezoelectric Energy helps charge the street lights, similar to a hybrid car.
but how does the electrical current effect the crystals on molecule scale?
they may change shape overtime.
this is just freaking amazing
I'm actually learning about this right now in my intelligent structure class
animation is top notch
as I am not an electrical engineer nor anything similar. Mind = Blown
What if we used these crystals at concerts? The noise would be converted into electricity, which can be used to power the equipment.
In technology nothing is absolute ,we always have something to upgrade and move for better technologies.
Excellent explanation..... It will be used to my seminar presentation on piezoelectric materials
I love the personality Karrot the animator gave to the orange hair glasses girl.
It's not "Positive/Negative". It is a direction of flow.
Very well-done video! Precisely what I needed; thank you!
Now that I know it would cost so much to produce the material composed of crystals, I can shelve the idea. I could never save enough energy to pay back the production cost.
why I never heard of this awesome discovery ? damn
the animation was LIT.
Clever, using people's activity to power the lights.
One of the few things I already knew!! YAY!!
i like these types of ted ed videos
Awesome animation, nicely explained. I also wanted to know that for a while but noone knew and i forgot about it.

This is awesome! Thanks TED-ED !
bullets that fry electrical circuits? Fusion reactors that generate heat on their own? Spaceships that gain power by colliding with specks of dust?
Wish if ted ed videos were long enough
These animations 😍😍
If I remember correctly, silk and other piezoelectric fibers have been proposed as a power source for computers integrated into clothing.
Yup..got it
Thanks for the video, y'all did a great job! I love the visuals

"Unit cells which lack a center of symmetry. " underscored
Is this what smarter every day once talked about? Now we have the answer!
beautiful animation as always
This is so fascinating !
Is this why so manny sci-fi films/series/books use crystals lie a source of energy?
TED-Ed, the only youtube channel not asking for subs, likes or comments
That was an amazing video ... my mind was blown
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.
Thank you.This video is useful in many ways.
Schools should learn from Ted-Ed
HOLY SHIT HOW DID THIS DISCOVERY GO UNNOTICED?!?!?!?!?
I remember that back in the day mica the mineral was used to make computer chips
Thanks for the clear explanation and the funny animation as always.
But, please stop torturing a robot by electricity lol
This video was pretty informative about piezoelectric materials, It's a bummer that I already knew about this stuff for a long time now which kinda made the video less exciting. I guess the only thing I learned is the atomic structure symmetry.
Shoes that charge your phone?
Yes please!
Piezo crystals are in acoustic guitars.
This video was sooo amazing and unique!! I loved it!
Superb !!!!! Now words to describe
Amazing animation and flow of information.
Magic crystals are real.
The first practical application lol , um what about the great pyramid as only one example? Ancient civilizations all over the world new this and applied it practically, just look at the high quartz content in the materials used in construction no coincidence
what makes Crystals to produce electricity? is it really squeezing causing electrical disbalance or vibrations?
