How to squeeze electricity out of crystals - Ashwini Bharathula

[@patrickbrumm420]

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.

[@solaria777]

So you rubbed two crystals and they started to glow with electricity? Thats neat

[@elyeyi369]

Are you serious? That's possible?

[@jamespotter1436]

That sounds sick

[@monkpool]

Unpolished crystals are powerful

[@SilentSnipest]

This is a fantastic animation style.

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?

[@KevinSalim]

No I don't, but I'm replying in case someone explain it :D

[@ChangeUrAtOnYT.comSlashHandle]

Well, fuck. Not even I knew that. Thanks for mentioning that, mate.

[@Darsh0019]

Mira Jain replying to learn more about this

[@נועםנגבקר]

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...

[@KezzaFTW]

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.

[@Pureignition58]

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.

[@DavidAllen-px7gr]

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...

[@chaorrottai]

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.

[@logout52hz]

[@ryannu1578]

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

[@ryannu1578]

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

[@johnhmaloney]

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.

[@spacewalker9375]

I'm actually learning about this right now in my intelligent structure class

[@Alex2Buzz]

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.

[@KentTheExplorer333]

If you use electromagnetic fields to "squeeze" the crystal instead of doing it physically the energy output would be exponentially greater.

[@itsrtvbaby]

Is this why people "charge" there crystals using the sun?

[@cavv0667]

What I'm missing here is a mention of how efficient this technology is... Always with the missing information.

That's why I love crystals, however, is it possible to power a motor or engine with piezoelectricity only? How much of them would be required?

[@oreole9608]

a *lot.*

[@zeddy5085]

I'm pretty sure if you had enough of them to power an engine, it would weigh so much that the vehicle couldn't even move. TL;DR a *lot.*

[@emedi.09]

as I am not an electrical engineer nor anything similar. Mind = Blown

[@palaurunpis4145]

instead of making roads out of them why not make shoes???

[@chriszhao1736]

Would you like to walk everywhere with cords attached to your shoes?

[@IQuick143cz]

So having a cable sticked into the ground while walking is better?

[@ChangeUrAtOnYT.comSlashHandle]

*stuck

[@adamriaz8203]

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.

[@IQuick143cz]

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".
