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.

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?

@@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.

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. 👍

@IronicHavoc
@IronicHavoc Рік тому
@@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.

​@@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 Self-education is only possible with a good knowledge of debate.

@@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.

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.

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)!

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.

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.

@eekee6034 2 роки тому
@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.
