Piezoelectric materials generate electricity when they are mechanically deformed. In this video we show how this can be used to make a simple circuit that stores the energy in a capacitor and lights a LED.
Capacitor is 20 uF @ 25 volts and resistor is 2.2 k. - วิทยาศาสตร์และเทคโนโลยี

Great video on this unique feature of the Piezo buzzer. Thank you very much.
A really nice video sir. Clearly understood how a Piezoelectric materials works. :) Thank you ....
Thanks for this video. I've been looking all over where I could find these piezoelectrics. Now I am inspired to make a project.
clear. simple. repeatable.
thank you!
Perfect demonstration.
I learned a lot from your video. Thank you very much.
Because I don't have knowledge about electricity But with a little knowledge about the mechanism so
The ideas and inventions that I create can come true.
I like the way you explained all of those thing's purposes..
What was added to electrify the output? Thanks for this incredibly helpful video :)
A cool demonstration.
Hi! Can you please tell what values did you use for each electric component?
great demonstration!
thanks
I put a short bit of plastic line in a drill press and had it strike a peizo disk to see if it would trigger a transistor pulse motor. The pulses looked good. Takes the place of the reed switch.
You did a great job by lightning a single LED using 1 piezoelectric
Thanks, brother, for explaining the concept
Hey, can you please tell me which size or what capacitor should I use? I am planning to do this for a science fair and i will be connecting 4-6 of these transducers in parallel (or should i connect in series) , thank u..
good explaination
So small and so powerful!
i have learned so much from your videos thank you.
Glad to hear that
Now make a stack of piezos to produce enough energy in one go
In fact, making a stack will just divide the amount of energy you give by pressing on it... with some energy loss due to heat caused by the pression. Plus you'll need to press harder because of the added thickness...
it is very useful
thank you and we wish to see more :)
ahmed antar Thanks! there will be more
Great presentation. Thesis: Line my tires with piezo sensors to generate enough power to......(wait for it).......run my car! :-)
what instrument do you use to measure resonant frequency of vibration or sound produced?
Yoshigo
Hi I wanted to ask if the soldering in the piezo is too much does it affect the overall performance?
Hi, and thank you for the nice demo! I am interested in reading and sending (wireless) the voltages given by a piezo strip, any suggestions on what voltage sensor I could use? I was able to read voltages of up to 24V from my piezo strip, but I don't have a data sheet with more details. Any suggestions would be appreciated. Thanks!
eusiegoulmeu I don't think you can do that, the piezo current is very low.
Excellent video!
Oden Knight Thanks!
Awesome idea
so if I was to install these in my foot wear and use a Peltier for thermal or heat charge and have a useful amount of energy storage. Any chance of charging a battery pack with the usage of a kinetic device?
If they used this in video game controllers you won't have to recharge the controller
Haha
Gijs It Creates very small amount of energy its so hard
TheFastly but using a buckconverter or other voltage booster can be used for getting that much electricity
+Alfash corpwannable
are you dumb?
Lol 😝 BRO
very useful video. thank you.
Can we use OpAmps?to make higher voltages?or does any limits exist for using higher capacitors or more complicated circuits?
can you please tell me how much farad of capacitor and which diode you have used to convert negative voltage to positive....
Hi please where I can find 20uf and 25 v capacitor please
Congratulations ! Awsome presentation! Can you please tell me how i can charge a cell phone using piezoelectric sensors?
You are great!!! Master!!
Thabk you for this video
i am interested to know more on this piezoelectric generator. where can i get one
Connect in parallel or series or mix which one is better ?and why? Thx
U r videos are interesting
Hello can I ask where can I buy a piezoelectric energy harvester online? Thank you
Is it possible for piezo to degrade over time? I'm troubleshooting a digital watch which no longer beeps. The rest of the watch works and the tiny spring is in place. I used your pressure technique to connect a multimeter to the piezo (which is stuck to the back of the watch) but didn't get any volts.
May you give me a link, for that piezo-element?????!
your video was awsome but i want a simple circuit diagram please share the link
thnxs very very, much it works!
Hrishikesh Patil Great!
Can you just hold and squeeze and keep squeezing to get a continuous charge from the piezoelectric crystal
bodacias402 yes but it will not be continuous. you will get a voltage only the moment when you squeeze
That is great! Can you tell the type of the piezoelectric material you are using? and the substrate also..?
+Nicky D'amico I used the piezo element from a common buzzer.
Can i use ir for drum trigger?
You could use full wave rectifier to charge it. It would be more efficent. :) Thanks for clear instruction :)
Aaron Sarrafoğlu Yes that will increase efficiency, thanks!
Have you any calculations for this ?
is this true for ANY piezo-element?
how did you get the piezo out of its shell without breaking out?
Hi, I am a sound engineering student at Argentina. Lately I've been working on hydrophone designs for cetaceans sounds. I used 160kHz piezoelectric crystals and achieved an acceptable result for Narrow Band Ultrasonic Frequency clicks emitted by dolphines. However, I had a poor response in audible frequencies. If I want to use a hydrophone for audible frequencies, should I use crystals with a resonant frequency bellow, within or above the range of interest??? Why???
Hello!! im a highschool student and I want to do a project where I use a piezoelectric material to convert sound waves to electricity, is that possible?? If it’s possible can you please help me on how to make it work or how to do my research about it?? Thanks in advance.
what are the specifications of capacitor and resistor?
well explained i am gonna make a video on this topic
Woww.. Wonderful..
Whether this piezeo electric plates are arranged in series or Parallel in order to voltage of 100v
Sir thanx for the video shown please tell what type of capicator and diode and resistor used and what rating of capacitor,diode and resistor
+maddipati surendra Capacitor is 20 uF @ 25 volts and resistor is 2.2 k.
can u list down the compt that u use.
Muito bom que tal fazer um teste(( junto com vibralert )) de telefone ja que funciona com pulsos dar um (start com 5 v ) !!! Abraço
it only powers a tiny light for a few seconds? how many presses would it take to charge a phone?
where we can buy piezoelectric generator offline at which type of shop.
Ludic Science where do u get these from? what website? give me a link
can we use multiple Piezoelectric together as generator, any idea how can do that...
hey, try to put this pieso betwen two iron core of 50 hz electromagnet. The core vibrate and pieso produce a voltage.....good luck!
Green Latern is there anywhere I can read more about this please?
What size of wire is suitable to solder in the ceramic transducer u use. Also stranded or solid
+JD Punzalan almost any wire works, it is not critical.
Does anyone know what kind of piezoelectric disk it is? Also the LED?
What type of capacitor and diode did u use in the second part? I am looking to resteste your project
Aldo Sanchez check description.
How many Amps did the Rectifier diode you used take?
+Matt Bilik 1
superb
can we use any capacitor
Tnx i make floor of my house with this piezo!
halfwave rectifying for great efficiency. much smart! such genius. cool, very?
You could add a rectifier bridge instead of a diode, in order to harvest both ways of the current instead of just one. (the resistor would charge twice faster)
but that would also have twice the diode drop tho
Great four play
+Lucid Science
As the capacitor is always connected to the piezoelectric element, isn't it discharging the energy stored against the piezo? Do you feel any increasing resistance on the piezo surface (by touch) when you have pressed the piezo a few times?
Thank you!
+DoNotPushHere The diode blocks the current from returning to the piezo
Ludic Science
Idiot me... Of course... =) thanks!
Sir what is the maximum possible and practical voltage that these piezos can produce? And can some kind of an arrangement be made to produce constant output voltage?
The output voltage is depends on how big the module is and how much pressure is applied.
As for the constant energy output I would recommend a capacitor and a step up voltage board.
may i know the resistor and capacitor values??
Hi good afternoon, is it ok if i dont have a switch?
thank you
i am making a e bike so i am placing this piezoelectric generator on wheel so wile ridding the cycle i the battery will get charge so how much piezoelectric genrator i need to place and i want to charge a 24 v battery. plz help me
What is the specification of the capacitor you have used. please reply its urgent
Looks like 22uF 200V, see 1:42 on video. 200V is too high, 20V is plenty.
Can we run a dc motor using a 20mm piezo electric disc
What are specification of capacitor and diaode. I tried with 220uf capacitor and IN4007S Diode but it isn'working at all and capacitor is not charging please help. I want to use it to charge a 3.7 v battery. Please help.
nic video but what is the value of resistor used????
what diode r u using
What is the value of Diode and capacitors. I did everything as shown in video with 220uf 16 v capacitor and IN4007S Diode but capacitor is not charging, and I am not getting any output ,out of diodes(rectifier) on multimeter in my case. What are the value of diodes or rectifier if I want to buy???
If i connect an piezoelement to a 24x7 vibrating machine what would be a lifespan that piezoelement and if i stack those ...what difference would it make in power generation and its lifespan?
*WHO NEEDS COLLEGE* - *WE HAVE THIS GUY*
How much amps or milli amps does it produce?
Hi, I don't know very much things, but is it possible to replace the capacitor with a ultracapacitor 2600F 2.7V ?
nycoshouse No. the cap is too large, the piezo does not produce enough energy to fill that capacitor.
very gooooooood man
:)
where I will get it online link for Asia or world wide dilevary
if i want to do the same thing, except store a lager energy bank, is it the higher voltage i look for in an capacitor or the amount of micro farads?
+Rory Saba Both
What type of diode
Sir? what are the things we need to make a Piezoelectric Generator
Hello i want to use the speaker like the one you have in an ultrasonic humidifier but cant seem to think of a way to go about it please help as i need to put the speaker in water
+Vanesa Lusaria I do not understand what you want to do. do you want to generate voltage with that speaker?
can i use many (20 for example) piezo elements in parallel so that i can get more current and charge a battery?
dimos geo Yes, but nothing comes free... with 20 piezos you will need to apply 20 times more force.
what is the number of the capacitor and the diode
i tried this at home. I tried to charge capacitor but it kept rapidly discharging. should i do it too rapidly? i was doing it slowly.
nice one
Thank you for the video. If I wanted to use more than one piezo connected to the same capacitor, is it possible?
synenvi yes, it is possible.
Ludic Science Thank you for your reply! So I have to take all the piezo and join all the negative and positive? (as a parallel connection). And rectify the common positive with a single diode? Or should I use a series connection? Thank you
synenvi every piezo must have its own diode, then you can wire them in series (for more voltage) or parallel (for more current)
Thank you very much! I'll try as you said. Last question: what about Graetz bridge (or diode bridge)? If I use it instead individual diodes I could increase the "flow" to the capacitor and load it faster? Considering that I have to generate maximum energy from very low movement of the piezo (music on a resonant surface). Thank you for your support and kindness!
synenvi yes a Graetz will improve efficiency a little bit
