Certain crystals, like quartz will produce a voltage when hit. It's all to do with the arrangement of atoms and charge in the lattice. It's used in lots of things like piezo lighters, sensors, speakers and oscillators for timekeeping.

If you rub two quarts together it produces a really cool lighting effect, that jumps through the insides of the stones. Very very cool, I use it when camping to make my friends think I’m a wizard
😂
Two quarts of what
I always cordoned off Piezoelectricity as one of those things I just wouldn't ever really understand. It's sort of delightfully simple thanks to your breakdown! Really appreciate this video, it opens up a better understanding of so many electronics.
now the question remains, is a voltage being produced by the impulse or impact from compressing/deforming and relaxing the crystal, or do you think a constant pressure would yield a constant voltage?
Where does the Cristal recharge it's charges from?

@@GabrielCazorlaPersson1 - Are you familiar with the Earthtide theory as the mechanism for Earth's magnetic field? Imo it makes more sense than the core dynamo hypothesis. The gist is that 95% of the Earth's crust is quartz-based, and that tidal forces from the Moon produce a diurnal flexing on the Earth's heavily faulted crust, which generates a piezoelectric field - "magnetic field" is a misnomer. Anyway, it solves many of the mysteries associated with the field and provides predictive ability whereas the dynamo theory does not.
Thanks Steve
Steve covers an amazing range of topics - chemistry, electronics, physics, crystallography and more. Probably one of the best channels on TH-cam.
1:57 fun fact: when you take a rock with lots quartz in it (say, a large chunk of quartz) and rub it against another rock (it's best with another large chuck of quartz), the quartz will make a dust (that is *hazardous to breathe in* ). Those tiny flakes break in such a way that rubbing them will create light. 👍

This is amazing, I had no idea that's how those lighters worked.

You mean 'scientists' ..

He had me until he said chakras don't exists 🤣a bit ignorant for an intelligent man. But that's okay a little research will enlighten you.
@@jeffv2074 that’s because he’s talking about things that exist in real life and not how you feel. Nobody cares how you feel, it holds no bearing on reality. Your gods are fake, your chakras are fake, your demons are fake. It is a waste of all of everyone’s time to speak on the subject
@@jeffv2074 I won't say Chakras definitively don't exist, but you should at least respect it's not the same realm of hard science that this video covers - i.e. directly quantifiable materials physics.
At best it's a "softer" or more holistic science closer to the realms of medicine or neurology/psychology. And even within that realm the notion of Chakras is not super well supported in any sort of large scale, peer reviewed, replicable study (that I know of). Which again, doesn't mean it's wrong necessarily, but it's entirely understandable why some people would have doubts about it.
At the very least wouldn't be as condescending towards skeptics as you're being. You might be surprised to learn there's a lot of very intelligent people who don't believe in Chakras. Granted I also know plenty of intelligent people who *do* believe in chakras and various other spiritual/semi-spiritual concepts. But even among the latter group I've met, I don't think any ever claimed that there's convincing concrete research behind it at the moment.

Many years ago my 8 year old son asked why two quartz rocks make sparks when you bang then together. I had him forward his question to a CBC radio science program. Their "expert" gave a totally unsatisfying answer.
You sir, have satisfied my curiosity! I'll forward the link to this page to him....I'm sure he'll appreciate your explanation.
Interesting fact:
"Piezo" is a greek word ( Πιέζω ) meaning "I compress"
Which, in narrative terms, is approximately the opposite of "I digress".
Quartz protec
quartz attac
but most importantly
quartz piezoelectric
Which is funny, because “electric” is also from Greek - electros, meaning amber, since static electricity was first observed by rubbing silk and amber.
So, it means “I compress amber”

U reminded me of my high school teacher who would go extents, to make students understand the beauty of science in everyday things. Loved it man. Excellent work.😊
Captivating and inspiring an audience is a rare ability
These types of teachers are the only ones I really learned anything from, because I could relate to every day life, this stayed interested.
It's good to see that you don't try and impress your audience by speak too quickly like most TH-camrs.
Your teaching is very good because of this. You take the time to explain things in detail.
It's about time a TH-camr had the sense to know that an audience learns better when a teacher explains things at a slower rate than other TH-camrs priding themselves at how quickly they can speak.
ur very lucky to have teacher like that
I've been looking at how this work for a while, and you actually explained it in the most simple and understandable way. Thank you very much man!
This is amazing. I am so fascinated with Quartz. It is mind boggling what this stone is capable of. This is not just a shiny stone! Thank you for making such wonderful and educational videos.

@@bhogarsishyan5769 Fooling manipulable people is not funny, we are not laughing.
The fact that people buy these is seriously concerning, as it is not "alternative medicine", it's just a placebo, and for a high price.
Accepting the existance of things like chakras without any sort of evidence for them is very childish, same with other dogma.
Scepticism is the thing that makes the scientific method the best way to obtain truth about our surroundings: constantly checking if you are wrong, not if you are right. Once you realize that "alternative medicine" (like crystal-healing and homeopathy, etc.) is not medicine, simply a psychology trick to take your money, you might actually start learning that the world is not so simple.
It's also good to eradicate your biases, for that I'd recommend yourbias.is , for not commiting logical fallacies, I'd recommend yourlogicalfallacyis.com

My friend... I'm 34 and I've tried to mentally visualize how this stuff works, and I've watched many videos in my time on TH-cam, but you nailed it. This is amazing! I am gonna watch more of your vids and subscribe!
The presentation of this was amazing. Each idea flowed to the next, very well thought out.
MR.MOULD, YOU HAVE NO IDEA HOW NUCH I LOVE YOUR VIDEOS AND HOW MUCH YOU'VE TAUGHT ME AND KEEP EXCITED ABOUT THESE PHYSICAL PHENOMENA.
I'm a dentist and we studied about the piezoelectric theory in orthodontics (braces work). Yes piezoelectric happens in your body too, but i never quite understood what it really was.
There are a lot of stuff we study and just get over it not actually quite going into the depth of each phenomena (for understandable reasons) and i wpuld stop and think about them. Somehow too often i end up finding a video of yours explaining the phenomena and satisfying my curiosity.
So thank you Mr. Mould.
I've a deep passion for learning. Alhamdulilah.
Steve, thank you for helping me to understand,( what would have been) something waaay too scientific for me to grasp, by keeping it simple, to the point, and the visuals. (I loved the peanut butter lids)
I am a crystal collector and I have recently become very intrigued by orgonite crystal pyramids (have you heard of them?) and how they work. I was skeptical as to if a man made construction as such could actually produce piezoelectric energy as they claim, and thanks to this video, it all makes sense. 👍🙂.
Some people believe the pyramids in Egypt were power plants. They say the outside was an insulator, and the inside was a conductor, and when the ground water would rise and fall, energy was generated. That may be a reason it was such a huge accomplishment. Idk about the crystal pyramids, but I'll check it out.
HEY!

Dear Steve Mould, this is an absolutely great video. Thank you for sharing that knowledge in such an efficient and easily conceivable way.
Absolutely love your presentation. Very succinct. And clear! Self educated and rely on guys like you to do my reading and homework, condense and pass along. You should write a book. Reading and watching are my learning strengths.
This was the most amazing video i have seen this year. You brightened up my mind too much. Thank u ❤❤❤❤❤
Fantastic video, as always.
Another interesting use of piezoelectric crystals is when you need extreme accuracy in the measurement of distancies (for example in interferometers), by applying a small voltage to the crystal you can shift it's length with a resolution of a fraction of a nanometer (10^-9 meters)!
Thank you, you just connected a lot of dots in the knowledge I have
You put so much work into each video, don’t let anyone tell you eating peanut butter isn’t work. I learned about lattice structures and piezoelectric crystals on Star Trek.

6:40 you just explained piezoelectric pickups for guitars! Thank you good sir
Great, another creator I gotta sub to because they make good content *sigh* my crowded dashboard, woe is me. 😉
I remember an old interview with guitarist and multi-instrumentalist David Lindley, talking about having used earthquake sensors, little piezoelectric discs, as guitar pickups.
What is this? Something to record the guitar from inside?
@@Enrique-peralta , since piezoelectric crystal's produce voltage when vibrated, you can stick them inside the body of an acoustic guitar and they will pick up the vibrations of the wood, which is somewhat analogous to the vibrations of the strings. The trick to getting a good sound, of course, would be placement of the piezo pickup, or pickups (plural), and whether you blend it with some kind of internal or external microphone or even a magnetic pickup that senses the string vibration directly. At least one company makes piezo type pickups that go underneath the bridge saddle and have six individual piezo crystals for the contact points of the six strings. I don't know what the favorite pick up systems are now, but back in the 80s and 90s Sunrise and Fishman, and to a lesser extent Barcus-Barry, were the ones that people were mostly using. I believe at least one of these systems had an internal microphone as well as the piezo pickup.
I thought they worked by em induction, oh i guess multiple types.
Up until recently I thought the spring-loaded mechanism was forcing a magnet through an inductor. I'm amazed at the amount of voltage

that might work aswell though and it has a similarity in usecases as it aswell is used in audio equipment.
I always assumed lighters just used a flint striker to make the spark that ignites them. I never considered that peizo electricity would be easier/cheaper/better than a basic friction striker.
@@jasonreed7522 the problem is, sparks from a flint aren't electric and can't go through metal
I'm a biologist, but our confocal microscopes also make use of the piezoelectric effect.
To adjust the focus, there are of course mechanical gears that adjust the position of the objective relative to the sample with exquisite precision. But for some application where both speed and even higher precision are needed, microscopes can be outfitted with a piezoelectric focusing system.
The range of motion is smaller, but the objective can be moved tiny amounts with a precision down to 10s of nanometres within microseconds. This is especially useful for certain modes the microscopes can use, such as resonance scanning mode, which allow us to capture images at very high speed in the xy plane. The piezoelectric focus adjuster gives us a matching fast way to adjust the z-plane.
I don't know which specific materials they use, but the principle is the same. By applying a specific voltage, the crystals deform in length and can be used to position the objective.
Another common use is in ultrasound machines where the crystal is used as both a speaker and microphone/reciever.
Same with drive-through speakers.
A good content as i expected, sir thanks for this informative video
It's not a great content, but it is a content.

Me at the beginning: "Piezoelectric," sounds like a Piezo pickup.
Me at the end when you used it as a microphone: OH THAT'S WHY!
Logan Strong Hi I’m an elementary audio guy here, what does a Piezo pick do?
@@natheniel it's a pickup for acoustic instruments, like cello or acoustic guitar. Idk exactly how it works, but by the name I'm guessing it's the piezoelectric effect.
As the vibrations travel through the crystalline structure theres compression and expansion happening, producing an electric voltage. Well, something along those lines anyways.
@@natheniel Also known as contact microphones, they are used to pick up only the sound from the instrument/object they placed in contact with, not picking up surrounding air vibrations like an ordinary microphone, isolating the sound.
The sound waves (aka compression waves) in the instrument's body make its way to the piezo pick-up and consequently compress it, in turn generating an electric signal which is then sent to an amplifier. Piezo pick-ups work better when they have direct contact with a hard surfaces as you might've guessed from this video.
Thank you very much for the amazing explanation!!!
Love this, takes me back to my days with the old toy crystal radio
Crystal radio?
@@Slay_No_More Oh yea; you can find an article about them on wikipedia. Basically you take a coil of wire, a capacitor, a crystal detector, and earphones to make a simple radio. Moving the contact to different spots on the coil lets you receive different radio frequencies. Some companies sell little science project kits of them

It will only open your third eye and align your chakra colors with the magical powers of its piezoelectricity if you *INSERT IT R E C T A L L Y* !!!
One of the most exotic and nonintuitive uses of the effect is for making electron beam evaporated optical coatings on glass. Little wafers of PZ quartz are located in the vacuum chamber near the glass and the change in resonance frequency of the crystals corresponds exactly to the amount of reflective material that's been deposited thus far. It is exquisitely sensitive, nearly being able to sense the weight of individual atoms and is able to detect coating deposition rates of mere angstroms per minute.
Another Applied Science fan? :D
You are fantastic! Thank you. Nicely expressed and presented.
Peiezoelectric pick ups for guitar is the first thing that sprung to mind. I remember faffing about with a speaker when I was a kid, and realising that it worked as a microphone. I love this guy's videos.
This is an amazing explanation. I have often thought about this myself, especially because a lot of acoustic guitar pickups use this effect.
@slayo 66 I believe those use a different approach, with magnetic fields, but I am not sure exactly how.
And that's why if you use nylon strings on an electric guitar you won't get any sound.
@slayo 66 Electric guitar pickups have weak magnets surrounded by coils. (Or maybe just 1 coil.) When the steel strings vibrate, the magnetic field varies with them. The coils produce electricity in response to the variations in exactly the same way as the coils in a car alternator or power station generator, but obviously at a much weaker level.
Very interesting video. I used to work for a company in San Jose, CA that designed and manufactured silicon microstructures that behaved as either pressure sensors or accelerometers. These devices were designed as a essentially a "micro" piezoelectric device using a Whetstone bridge as the primary circuit. Wow, that was over 30 years ago now!
Your humor is very subtle. Superb
As calm as you sound and simplicity in the way you're describing details of known components, if you're not an instructor, well you'd be a great one.
I actually use piezoelectric actuators a lot in my work, but I never pay attention to how it actually works in molecular level until I saw this video. Thank you for the effort!
