Introduction: Piezoelectric Generator

hello frnd,

i come with new attractive ,easy and smart power generation idea which is useful for your smart project and give new way of creation .

piezo electric power generation which is fully depend on applying pressure on piezo transducer,

Step 1: Collect Wooden Plywood As U Want to Make in Your Size

cut as per images .

Step 2: Buy Piezo Electric Buzzer at 20 Rs Per Pic and Modify As Image and Get Piezo Transducer


Step 3: Draw Square Box to Attach Use Box As Per Show Images,,, Buzzer Upper Parts Use for Making Top Part to Press

Step 4: Make Series Connection of Piezo Transducer

Step 5: Finally Glue or (use Plastic Tap )on Series Connection on Down Part As Shown Image

Step 6: Start to Generate Electricity by Applying Finger Pressure ,,,

Step 7: Generate Electricity While Walking Homemade

Sir as I can see there is three wire one is connected to feedback part another connected to metal part and last one is connected beside the feedback part . So at the end we can see two wires make connection finally but third one is still why we are using the third wire which is beside the feedback path.??

Those piezos produce high voltage (easily 40V) but only very, very low current. So the wattage you can get out of that is only in the micro Watt area. At best you can lit LEDs for a short time.

hello sir, but i have one idea ..use rectifier ckt to convert ac voltage to dc ,and also use dc charging ckt store battery whenever u can use...

That won't work. To charge a battery you need a constant current. And one that is much larger than any piezo can deliver. I have seen university projects to get energy from cars driving over a street. It can illuminate a side strip or middle marker. But then it's incredible expensive. You can use those piezos as sensors to detect movements or even use them as microphone. But energy harvesting: no way.

I'd love to know how they built that nightclub that is powered completely by peizoelectric panels on the dancefloor works then.

it is possible as I've seen various successful projects. But I have no idea of the circuitry.

id like to adapt something for charging lithiums.


not strictly true, you can use the small pulses of current to charge a capacitor,with the correct circuitry you can them 'dump' the capacitors held charge to the battery. I have used similar technology in devices with solar panels where the sunlight is not reliable but there is power to be scavenged


I agree. I had tried this a year ago to charge a cellphone battery, they dont work.

Courrent is less than 1 mA for 6 piezo in parallel.

But though Nice instructable.

Hello, I have a question concerning the piezoelectric devices used in this project. As it turns out I will be needing a piezoelectric generator circuit. The idea is that the piezos will charge moderately large capacitors which will then be dumped into a battery with some extra timing circuitry. However, I have not developed a circuit yet because the rochelle salt crystals I tried to grow were unsuccessful. So, instead of wasting my time, I went to Amazon and bought some piezoelectric elements marketed as guitar pickups/drum triggers. Will these work?

n Spain there is a small company that manufactures electric generators obelisk-shaped piezoelectric operating with a base and the movement of wind, thus avoiding the huge blades of the wind turbines that threaten the birds' migration routes. a larger obelisk captures more wind and produce more energy. for now they are struggling to break through against traditional energy production system and the pro-establishment

Awesome! what if I made four of these plates and placed them under my car tires?

Unfortunately, it doesn't really work that way. In a piezo generator, electricity is produced only when there is a press AND a release. So, if you simply keep a heavy book on top of these generators, there will only be a short burst of voltage and after that no electricity shall be generated. In contrast, if this is accommodated into your shoes, you will be able to generate significant amounts of power since the piezo will be pressed and released continuously.

hello ,,,, of course ,,u can put but u have to make down part from metal thin plates and upper part where i apply pressure there make from rubber ..try it ..Have a great fun ...

DonCesare (author)niravpatele632015-12-13

Amazing!!! Thanks a lot I will sure try!!!

piezo elements are a lot of fun to work with.


Yes ,try it at home to make it cost is around 250 Rs it is low budget homemade project..
