This electronics video tutorial provides a basic introduction into the piezoelectric effect which uses crystals to convert mechanical energy into electricity. This video explains how to store the electrical energy using diodes and capacitors and how to release that energy to power a LED or light emitting diode.

This is one of the best instructional videos that I've ever seen. You have a gift. Thanks and cheers.

U r all-rounder . In how much subject u r good in . Interesting man .

@jimmydylan4793 3 года назад

a trick: you can watch series on Kaldrostream. Been using it for watching lots of of movies lately.

@mekhibeckett7847 3 года назад

@Jimmy Dylan yea, have been using Kaldrostream for years myself :)

@tannercolson1886 3 года назад

@Jimmy Dylan yup, I've been using Kaldrostream for since november myself =)

Great demonstration and great lecture. The circuit construction was very clever. I liked especially the discussion about the deformation of how the Silicon Dioxide molecules generates electrical flow. Honestly, I don't think that I ever saw that explained before! I even bothered to click the thumbs up button! (don't worry I am subscribed)

so to those hollering not enough amps. guys just plug the voltage output of 2 of those piezos in series to ohms law. we already know a estimate of resistance in the wire based off the AWG it looks like hes using. those piezos are probably getting around 30v a piece. meaning 60v in the circuit. so 60v divided by the resistance of the wire which is about 0.5ohms and you get 120 amps. rough estimate... the energy your thinking of isnt necessary all from those value, but power over time as well or known as electrical charge. in that formula the electrical charge is dependent on the start and end time of the applied power. the longer the discharge time, the greater the electrical charge. knowing that, take a good look at his setup again. he specifically made the material to lengthen the discharge of the impact hence lengthening the time of applied power into the circuit. giving it a greater electrical charge than if only using piezos alone... formula reference (ohms law is basic and easy to find) electrical charge formula, watts law, voltage in series(for the 2 piezos in series) theres even formulas for coil gun energy using different types of cores and solenoids. take your time, learn some things you dont know yet and you will have a better understanding. its ok to not know. most poeple only have a basic understanding of electrical laws. theres a lot more to think about than first meets the eye.

The piezoelectric effect is so cool Love how you make videos on a variety of subjects. You're fucking awesome man!

@Axel-jv8wb 4 года назад

This is cool and simple like photoresistor

@peterv7258 Год назад

My question is, at the moment when the pressure is applied, i.e pressing the button, does it generate a continuous current, or is it merely a single pulse of electric flow?

@kokopelli314 3 месяца назад

Single Pulse

@ronash.a 4 месяца назад

Would it then be possible to convert soun energy, which is like vibrations and that, which are compressions, into electrical energy. Like is the materials that sensistive.

Excellent explanation, great work....keep it up...we would love to see more such

@pklearning-mathandstatisti7538 4 года назад

Still wondering whether this works as it is totally new to me! Great work!

@aTrainWreck100 11 месяцев назад

So if compression of quartz causes the electrical charge, let's say that I put a piece of quartz in a vice a squeeze it. Could I continually gather and store electric current as long as that vice is pressing down? How long would it last until the quartz stopped producing energy?

@asedonii-chan8466 Год назад

would you happen to know what is the most piezoelectric crystal? For some reason my google fu has failed me. I suppose to clarify I’m asking what crystal generates the most electricity through this phenomenon.

@jethronoahmoral9946 4 года назад

@ChrisTietjen_00 2 года назад

Where does the electron flow come from? In other words, when pressing the crystal are you "pumping" electrons out of the crystal and if so won't the crystal eventually dissolve? Also why does the relaxation of the pressure create a current flow since the crystal is going back to a balanced neutral state?

@chaklatech 2 года назад

If Im remembering correctly, it has to do with the crystals molecular structure and, when pressure is applied, the structure becomes disrupted causing electrons to flow. When the pressure is released the crystal wants to return back to its original molecular structure, causing the flow to reverse. Im not super sure I am correct but this is what I think I remember.

@winterender8663 4 года назад

Differentiation pls

@psixojohn6367 3 года назад

Great video, i needed that. I have only a question. If current doesnt flow through the capacitor, due to the dielectric, then when the switch is on what is happening?

@KLOC2812 Год назад

When the switch is closed (on), I’m fairly certain the LED would light up and the capacitor would charge at a rate decreased in line with the resistor added to the LED end of the circuit.

@ojoonaopemipo7085 Год назад

how much current does one piezo electric sensor/crystal genenerate

@saimittapalli9668 4 года назад

Yooo that's hella cool and useful

@claponclapoff6 2 года назад

Whatever happened to just wrapping crystals with wires and generating current that way oh that's right we're not allowed to

So this is how sound waves turn from mechanical waves to electromagnetics?

@global-hellsorosshjt5469 Год назад

There used to be "crystal" mics that used this effect ....also "ceramic". ....but they didn't sound that great. They had a high output though, at a very high impedance. I still have one; the Astatic JT-30.The crystal turns sound waves into electricity, not electromagnetic, although it could be argued that a flowing electron produces a magnetic field according to the right hand rule.
