  • can make a touch sensor

  • Add a rectifier circuit and it lights up when you release the pressure as well. A small capacitor might hold the excess charge for a second. I wanna build a carpet made of this!

  • I am very happy to see the vidoe after you give this can be used in reverse to generate a momentary voltage.

  • I Love The Video This short clip shows how an LED, soldered across the disks of a piezo, illuminates when the disk is tapped or pressed It Can Increase My Knowledge

  • Steady I Really Like This Video can be used in reverse to generate a momentary voltage

  • Good, I like that you share this video can be used in reverse to generate a momentary voltage, I wish success always

  • Nice Video can be used in reverse to generate a momentary voltage That You Share , So Very Nice Thanks You

  • I Really Like The Video From Your can be used in reverse to generate a momentary voltage

  • Your Video Is Very Useful Sharing A simple piezoelectric disk

  • i dont know how many times i have said this and no one has done it still ,,wy not stack hundreds in a car exhaust or under the roads man you guys are missing out

  • Would you like to give a reference to this Piezo? It's because I found one inside of a buzzer, but apparently, it doesn't generate the same amount of energy, I'd like to know. Thank you.

  • Where can i buy a disc and small LED light like yours?

  • Perhaps the roads should be lined in cross-section strips of quartz under the pavement with leads on both sides.. Hermmmmm Could light street lights, capacitors, perhaps even homes. And i wonder if rain could also strike it with enough force to produce electricity. How cool would that be!

  • Hi, i have to do a project for school, can you please tell me how can i make this myself? how do you make the disk or rather where do you get it from?

  • where can i buy it ??

  • lol, it really works! also the led lights brighter when you bend the piezzo rather than tapping it :)

    but... why does a piezzo produce more electricity than a normal speaker with a large magnet?

  • where can I let one disc of these? Ty!

  • stick it on ur engine block!!!

  • Can you give me the link of the data sheet for this please

  • Can you give me the link of the data sheet for this please

    

  • where can i buy it?

  • Hi, i am trying to make some project with this but i cant find this disk piezo in my country, can u help me?

  • @nahairavallejo

    you can find them in toys and minature radios and other electronics

  • Hi, i am trying to make some project with this but i cant find this disk piezo in my country, can u help me?

  • man, i want to do something like this, but im considerin a much larger light source, like a light bulb, can i still do it with a thing like that disk? also, what really is that disk?

  • where can you get one of these disks and how much does it cost?

  • @TheReasonWhyGuy Energy is never created or destroyed. An electrical generator utilizes mechanical energy to generate electrical energy.  You're arguing a moot point.

  • @thesinner85 agreed...

  • there is an alloy called liquid metal, it has the ability to store kinetic energy when hit or dropped onto a hard surface, try using a large liquid metal ball, set it on the piezo and then turn it on underneath the ball to see the kinetic energy of the bouncing ball being converted back into electricity.

  • Is there a recovery time of the piezo, or can you just hold it down for any amount of time?

  • Can piezo be usead as a switch somehow? with some added components or something?

  • @TheBetterPeter if it's an on/off switch and not only a pressure button, you can use an op amp and some flipflops.

  • i heard quartz amps electricity...is this true? if so i'll experiment by a copper wire coiled around quartz & still in its regular use to charge a batt. the other option i'll try too is having copper electroplated around it with wire still on both ends still to charge a batt. if it works enough i'll add this into my solar panel wire.

  • How much is the piezo?? and where i can find one like this???

  • @chil0man You can buy a piezo transducer at Radioshack for less than $5. They are used as simple buzzers for electronics. You just have to take the plastic casing off.

  • how many volt generated each time the piezo is pressed??

  • @mikothe87 enough to light a LED... its gotta be at least 2 volts... sick drumset light show, batteries not needed.

  • how many volt generated each time the piezo is pressed??

  • its a bad ass thing

  • In honor of Black History Month, let's pay tribute to NASA Engineer Joycelyn Harrison, who rec'd numerous patents and the 1996 R&D award, from R&D magazine for her role in developing T.H.U.N.D.E.R. technology (Thin-Layer Composite-Unimorph Piezoelectric Driver and Sensor).

    This gives a nice visual on how this technology works. Thank you for the upload.

  • that's direct piezo electric property when you make a force on piezo electric disk and then by processing of peizo electric it'll show the light... it's the mechanical energy going to be the electrical energy ... I was make some product test ... I use battery A , hook up like , and peizo electric disk..... btw this video is very cool

  • hey, im doing a project for design tech, where im trying to put a bunch of piezo generators in a shoe, and have the energy that they generate from the walking around stored and then later be used to be a charge for like a phone or something, do you think this is possible>?

  • you're not the only one, friend. google trevor baylis and his electric shoe. he is also the inventor of the wind-up radio. i also tried to design an energy harvesting shoe, but not practical right now for the consumer market.

  • cool! thanks alot, yeh in design-tech we watched a video on Baylis and the wind-up radio development. yeh im turning in my project tomorrow, and i discuss that. i say that piezoelectrics are becoming mroe and more popular in green energy, but for the moment its quite primitive as a technology. but who knows, maby someday.

    thanks again

  • Where can I find a transducer like this?

  • it will take 3ma to light up an LED, if we stack 100 of the piezo plates, that would not be too thick. That will be 0.3A current.

  • How can i make the piezo vibrate using Voltage supply instead?

    Ty :)

  • Hi.

    The process works in reverse, so electrical pulses cause the piezo to flex. This is typically used to make a tone, by applying a pulsed signal (the frequency determines to tone/note).

    I guess that this could be used to produce movement, but the flexing is very small on the disk piezos. You might get more by using piezo film, but I have never tried this. There are Electroactive Polymers (EAPs) under development that do this more effectively - rather like a muscle.

  • @StHelensEngineering I take apart electronics that aren't in use around the house because I don't want them to be thrown in the trash because of the metals. And one speaker that I took apart had one of these in it, and all I was interested in was copper. So I broke the peizo element thinking it was a protective film. So... these things are being used "in reverse" to produce audio.
