@@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.

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.

@@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.

Fantastic video, as always.

My favourite application of the piezo effect is a marine depth finder. Same element acts as transmitter and receiver. That's cool. Thanks Steve.

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.

Do you do MRI-compatible neurorobotics? My buddy Greg Cole did his master's thesis designing a piezo actuated brain surgery robot that had less than 1% MRI signal interference. They're loud as anything

I love the demonstration of "It is not a great one but it is one" XD

A máster in action. Your understanding of this phenomenon is such, that I finally got it. The lid diagram was the key for me. Thanks.

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!

daaaamn notification is so on! I WANNA SEE THAT QUARTZ vibrating video :D your videos are just amazing! Love it!

3 years old and still interesting!!! Amazing how much of that voltage is used everyday all around the worl,just lighting those"COFFIN NAILS"!!

this is a great video. Thank you for explaining why the butane long neck lighters are difficult to light (but you left out another main reason, they make them child proof now, lighters weren't that hard to light years ago, they didn't have the extra safety button you have to hold, so that factors into it). I bought a piezo electric long neck lighter about 5 years ago (primarily to light candles in glass candle holders where a smaller lighter won't reach), it works great, never have an issue lighting candles. Before having the piezo lighter, I used to go through many butane lighters, they would stop working quickly (even after refilling with butane).

100% i often remove the extra safety spring or try use a rly old lighter it annoys me i have to consider safety! Theres no kids getting it how about teaching parenting rather than making laws about safety lighters that then inconvenience me for a kid who dont exists safety! I hate the after 2000s world so much lol!

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!

As the vibrations travel through the crystalline structure theres compression and expansion happening, producing an electric voltage. Well, something along those lines anyways.

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.

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.

@eekee6034

@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.

A very exceptional channel, you explained Piezoelectricity, but introduced everyone to the edge of a whole new world that few understand. very definitely worth a tick and subscribe. (and yes I'm a bit spooked by long videos, definitely preferring the 2/3 minute Vids, but you can't spell something like this out in 2/3 minutes)

*points to 3 things with 3 separate hands*

I don’t know how you are really able to do it, but every video I watch of yours i can totally understand what you are explaining! :0

liked. subbed. when you said the video was already getting too long, I was like, what? no, it's not! more! more!! 😉 I could listen to your explanations all day. in fact, I'm going to watch the rest of your channel & literally do just that. lol.

The energy generation aspect of piezoelectricity is way underrated. Especially when thinking at large scale.

You are fantastic! Thank you. Nicely expressed and presented.

This is also a part of why load bearing exercise is important for bone density Ie calcium resorption!

Your brain can be considered as an electrical powerhouse, given its amount of connections, wiring and power consumption. Well, in fact, no, not a powerhouse; but rather something electrical, big, and complex. And stress surely increases brain activity.

I learned a ton. Thanks for describing the need for a lack of a certain type of symmetry for piezoelectricity to work. It leads me to my next question. Since there's so much quartz in the earth. What happens with the earth compresses with the gravitational pull of the moon?

@@DANTHETUBEMAN The positive and negative charge of the individual atoms? It does not need to recharge at all! (it does not discharge). When you apply pressure to a quarz, you bring the center of the positive charge and center of negative charge apart. When you stop applying the pressure, they drift back together. This 'drifting' of opposite charges creates a flow of electrons, or in other, words electricity. The charge of the individual atoms remains constant throughout the whole process.

Thanks for the video! What software were you using to visualise the crystal structure?
