Piezoelectric Generator 

You did a great job by lightning a single LED using 1 piezoelectric

Thanks for this video. I've been looking all over where I could find these piezoelectrics. Now I am inspired to make a project.

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.

If they used this in video game controllers you won't have to recharge the controller

clear. simple. repeatable. thank you!

Great presentation. Thesis: Line my tires with piezo sensors to generate enough power to......(wait for it).......run my car! :-)

A really nice video sir. Clearly understood how a Piezoelectric materials works. :) Thank you ....

Great video on this unique feature of the Piezo buzzer. Thank you very much.

Now make a stack of piezos to produce enough energy in one go

Perfect demonstration.

So small and so powerful!

I like the way you explained all of those thing's purposes..

You could use full wave rectifier to charge it. It would be more efficent. :) Thanks for clear instruction :)

hey, try to put this pieso betwen two iron core of 50 hz electromagnet. The core vibrate and pieso produce a voltage.....good luck!

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.

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???

Thanks, brother, for explaining the concept

*WHO NEEDS COLLEGE* - *WE HAVE THIS GUY*

good explaination

great demonstration!

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)

A cool demonstration.

Excellent video!

it is very useful thank you and we wish to see more :)

Use a super capacitor with 50 to 100 Fad to get the LED going for a long time. Thinking 🤔 of building a torchlight 🔦!!!!

Can you just hold and squeeze and keep squeezing to get a continuous charge from the piezoelectric crystal

What was added to electrify the output? Thanks for this incredibly helpful video :)

i have learned so much from your videos thank you.

i'm just a beginner so sorry my stupid question, but is that resistor put in wrong place in your drawing?

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..

May you give me a link, for that piezo-element?????!

So if you have multiple of piezoelectric discs on all freeways, roads , streets, the car tires would replace the hand actuator presses and the electricity would generate your night light and road signs or stop light . Interesting

Hi please where I can find 20uf and 25 v capacitor please

halfwave rectifying for great efficiency. much smart! such genius. cool, very?

I am not an electrical or electronic engineer so pardon if my query sounds ridiculous. 1) If i use a Battery instead of a Capacitor will i be able to store more amount of electrical energy? what changes i'll have to make in the circuit diagram? 2) can piezoelectric effect take place in the sole presence of vibrations by Sound waves? If yes How?

Hi! Can you please tell what values did you use for each electric component?

I love piezoelectricity, but could you replace it with a brushless motor and and make a generator?

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!

Please, I did this practical experiment. My AC voltage was varying , sometimes, 10V sometimes 2 V. That's not my problem, the problem I'm facing is, the rectifier circuit absorbs all my ac voltage and delivers value of around 0.5V as the DC output, please, what should I do?

Whether this piezeo electric plates are arranged in series or Parallel in order to voltage of 100v

Hi I wanted to ask if the soldering in the piezo is too much does it affect the overall performance?

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.

What type of diode

it only powers a tiny light for a few seconds? how many presses would it take to charge a phone?

what instrument do you use to measure resonant frequency of vibration or sound produced? Yoshigo

that's funny, I experienced the same logic before I watched videos like this.

where can i buy these

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???

can u pls reply why does it show negative value

That's good, but a note about pronunciation: Circuit isn't pronounced sirkwit. If you know how "cut" is pronounced in English, it's pronounced sir-cut, with an unstressed vowel in the second syllable. And LED is typically pronounced L-E-D, as three separate letters. Hope this helps!

Ludic Science where do u get these from? what website? give me a link

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?

Sir? what are the things we need to make a Piezoelectric Generator

Hi, I don't know very much things, but is it possible to replace the capacitor with a ultracapacitor 2600F 2.7V ?

Can we use OpAmps?to make higher voltages?or does any limits exist for using higher capacitors or more complicated circuits?

Awesome idea

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.

+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!

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?

Good day! Sir, Currently, this video is really similar to our project (thesis). Let me ask, "What is the mechanical energy harvested and converted it to electrical energy via peizoelectric disc"? Is it AC or DC?. **if AC what materials we used to convert it to DC? Overview of our project: Title: Acoustic Electricity Generator Objectives: -to design an energy harvester of audio signal for small battery-operated devices -to design a system that can harvest energy using piezoelectric disc (transducer) -to design a charge regulator and controller -to develop a battery-based charger Is it really possible to store the converted electrical energy into a battery? Also, how much is the current produced? We searched it, but find none. I read an article, 'Using several elements (piezodisc) that are mechanically in series and electrically in parallel is the only way to increase the charge output'. What does this mean? Should we connect the elements in series then,, don't know the electrically part mean. Thanks More Power! Yours, ECE students PS: Sorry for bad english, we are from PH by the way. Your idea will be gratefully appreciated. Do you have emails or fb sir?

how did you get the piezo out of its shell without breaking out?

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.

can you please tell me how much farad of capacitor and which diode you have used to convert negative voltage to positive....

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

Wouldn't you get twice the power using a bridge? it seems like you are throwing away the negative voltage pulse.

is this true for ANY piezo-element?

Hi good afternoon, is it ok if i dont have a switch?

You are great!!! Master!!

When did mourinho make a RU-vid channel? 🔥😂

can this theoretically charge a triple A battery?

where we can buy piezoelectric generator offline at which type of shop.

How many Amps did the Rectifier diode you used take?

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

Congratulations ! Awsome presentation! Can you please tell me how i can charge a cell phone using piezoelectric sensors?

I tried this, but the capacitor charges to only ~1.11V and refuses to go higher idk why. Please help. And what is the resistor value?

can we use multiple Piezoelectric together as generator, any idea how can do that...

Where did you purchase these chips? Can you share the link?

Why we r using diode and resistor in dis circuit ? Pls explain d use of those two elements in that circuit

That is great! Can you tell the type of the piezoelectric material you are using? and the substrate also..?

what type of diode did you used?

Which rectifier did u use? I am asking because i am doing this peizoelectric circit for science exhibition

Connect in parallel or series or mix which one is better ?and why? Thx

Hey, Ludic Science, I have a very similar design! My piezoelectric material is very inefficient. It does not generate enough voltage to charge the capacitor and power the LED. Do you mind telling me where you got your piezoelectric material from? Thanks in advance!

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?

How much amps or milli amps does it produce?

Heyy Lucid Science can you answer my question- can enough electricity be produced by an piezoelectric disk with a perfect circuit to run a DC motor??? If yes pls explain the circuit that is needed?? Thanks in advance!!

very useful video. thank you.

Hello can I ask where can I buy a piezoelectric energy harvester online? Thank you

i am interested to know more on this piezoelectric generator. where can i get one

What size of wire is suitable to solder in the ceramic transducer u use. Also stranded or solid

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

HI, I'm a student and I would like to know where did you buy your piezoelectric buzzer., please.

What type of diode, capacitor and resistor are you using? I am new to this stuff but am doing research. I want the output from the capacitor to be a constant 5V to power something.

can you shout directly at the piezoelectic element to light up the LED ? if possible , will the capacitor still needed ?

Could massive sheets a piezoelectric material be placed on the floors of a building to produce energy from the people walking around?

U r videos are interesting

nic video but what is the value of resistor used????

i am using 9 piezo sensors in series and parallel combinations.. they are not enough to generate voltage to glow a led.. what should i do

What type of capacitor and diode did u use in the second part? I am looking to resteste your project

Sir can you tell me how can we measure that pressure value that you were applying? i have project to measure the pressure using piezoelectric cell.
