You beside by thomas edison

happy to hear it.

Piezoelectric turns mechanical compression into energy. It might be more efficient to leave it as it is because it receives more leverage and thus more compression. Not sure, though.

Thanks for the sub!

Or car shock absorbers to charge the cars battery

ceramic, dry bone powder, silk are commonly used. But, in labs, it is mixed with some types of titanates for better result. You can make a bigger size piezoelectric plate but, for better output voltage, you have to give the pressure evenly across the plate.

Try with a transducer for ultrasonic cleaner (industrial or hospital grade)

Pls reply creator! Were trying to do this aswell for our proj. Can you reply?

I currently doing this for my final project but when i try to store the energy from piezo to rechargeable battery. It doesn't work, idk why

Spring gives more recurrences.

@@SKILFULLIFE Thank you for you reply me. that's mean peizoelectric with sping can make the voltage and the power more than another one right.

That's right. more vibration gives more power.

@@SKILFULLIFE Ah, I see so Thank you for answer me🙏

From a piezo disc, you can harvest less than 50mA and about 3V. To charge a powerbank, you need minimum 1000mA and 5.2V, So, you may need 25 - 30 piezoelectric discs in one row in series and you need 2 rows in parallel to get more than 5V. Note, all piezoelectric discs should be vibrated at the same time.

Most of the parts were collected from used electronic devices.

To get more current and voltage, you have to use multiple piezoelectric discs based on your need. But, each piezoelectric disc should have it's own rectifier. Then only, you can connect them in series and parallel to get your desired output. If you don't have rectifiers for each piezo, the power generated by one piezo disc will be consumed by another piezo disc and you can not get the maximum output.

@@SKILFULLIFE thank you Sir for clarifying that each pzts should have its own rectifier. But each rectifier will cause voltage drop n make more loss. Is it important to use the spring? Could I just replace it with hot glue?

@@meitungleong3048 Dude im doing a similar project!!!!!!!!!!!

@@larrykrepp7428 👋 Hi...Good luck to both of us. 💪 We can dicuss n exchange ideas if u wish to.. Even though I may not have good knowledge on it 😊

@@larrykrepp7428 hi, I'm doing the same project. Is ur project successful? I have been trying to charge the battery using the piezo for weeks but the current generated is really too low to charge the battery

Generating electricity from piezos by vibration of moving vehicle is possible but worthless. just wasting money and time. There are some ways to generate more electric power than piezo such as attaching a small wind turbine, solar panel, and thermoelectric generator(TEG) modules on the hot part of the engine with cooling system. Even, you can get more electric power from vehicle's alternator. Try to make a vibrator by using wind or sound energy from the environment to vibrate piezos to generate electricity.

@@SKILFULLIFE great answer! two thumbs up for your skillful explanation!

I tried in that way too, but it limits the vibration of the blade.

@@SKILFULLIFE i reckon the spring is too stiff? Anyway, just a suggestion for a different configuration experiment.✌

It is possible. But, there won't be raining all the time. Find a continuous vibrating source before you invest money.

@@SKILFULLIFEthank youu sirr!

More efficient to create a hold tank with nozzle.... Open nozzle to spin electric motor....

Yes, you can try that. But, you need another power source to produce more vibration.

@@SKILFULLIFE This patented device imo produces free vibrational energy. Thane Heins invented it 10 years ago, with dubious claims of achieving '96% recharge "capability" (not "96% battery recharge"). There is a big difference. The device has survived a frantic decade-long search for a 'research consortium', PhDs etc. to find the key to completion. I am convinced that you may be instrumental in solving this. You may know something or know someone . imo the path to success is piezoelectric. I bet Heins a $million that it turns out this way. Please, please have a look. Whomever solves this is a billionaire, btw, if it goes without saying: kzfaq.info/get/bejne/osxpddFyzb3Jp2g.html

@@SKILFULLIFE interestingly, the motor only does its thing (free acceleration/free rotational mechanical energy) when the device is brought up to/or beyond , a given rotational frequency/RPM. Which would also be a sound/vibrational frequency. He never drives it or adds a full complement of coils, because imo he is stumped. Additional coils doesn't work. There's not enough torque rubber to road. He is CLOSE to a miracle here.

@@SKILFULLIFE my intuition: electronically amplify the sound. Maybe a looped system.

Can u tell me why? Im curious sir

@@alvin8268 ac current is use to transport electricity at higher scale

Not cost effective

@@viralvideo171 look at Israel they have roads lined with this now

@@puttingtechniques its probable just not practical atm. With the cost vs upkeep vs power output it's not a wise choice when compared to other options. Definitely neat though for sure.

Ignore the third wire from the smallest area on the disc.

to power the LED

to get a regulated voltage.

To generate enough current from a piezo, it needs a continuous mechanical compression and decompression. Chair cushion can not give enough frequent of mechanical force continuously. If you do it so, it would take months to charge a power bank. To get a reasonable current, find something can give over 100 compression per minute at least.

How about loud sound produced in warehouse from equipement where protective ear plugs must be worn?

Yes by tidal energy plant

pretty sure we are already doing it

Actually, when you press and bend it one direction, the current flow is positive. When you press and bend it opposite direction, the current flow is negative.

It only generates electricity once pressed for a little amount of time, and then when released it also generates electricity in am opposite current direction, and again only for a short period of time. In other words it wont generates electricity once pressed for a long time, instead you need to release it.

No, you have to keep changing the pressure on it by compress and decompress to get the voltage continuously.

@@SKILFULLIFE thanks for the answer. Exactly what I wanted to know...

No, it should be oscillating.

@@SKILFULLIFE oh.. ok bro

I would suggest to use individual rectifier for each piezo.

@@SKILFULLIFE thank you for quick response, I will try to do that way. Do you have any advise to increase harvested energy (mean current)? I think about puting one on another piezo and between some separator it should double it.

Yes.

Piezo disc produces AC current. So, you can connect the wires from piezo disc to the rectifier in any way. Those silicone bumber pads.

yes, you can try.

sheit don’t werk that way bruh 🥵

Yes, you can.

@@SKILFULLIFE Thank you so much sir!

Put em inside your car wheel as your driving might work...add something else inside car tyre that creates a vibration from the rotation off the wheels your noisy boy racer cars would do the job from the noise n vibration those sods make lol

Furthermore as they so thin you could go one further n build a load so they absolutely solid can take punishment and put them on the tyre itself on the outside like a line off them all the way around the tire say one long strip or lots off these round ones and they will get the pressure from the entire car pressing them down against the concrete n would create a constant charge obvs a few kinks would need too iron out but yh plenty ways I imagine...combining all these energy pottentials together into sorta one unit or units get things working in conjunction and utilise all heat n motion n vibration no need for any energy too go too waist can all be harvested I spose...was just looking at those thermo stove fans that power on from any heat source so your wood burner say n makes fan spin which you can then attach a copper coil n magnet too the fan n turn kinetic energy into electric n charge some batterys or something just utilising the heat ain't ya rather than being waisted..cherrs
