Piezo plates....How To Connect In parallel Or series?

Hello Everyone...
We Have Some Piezo Plates And Wanted to connect them parallel or in series to make a circuit that makes energy to charge your phone...
We want to use them in boxing gloves or something like that to get sufficient energy to charge a phone....
Our Piezo plate has 3 wires as shown in the image...
Please provide a circuit diagram also....
Thanks for your help....

Like all batteries in parallel for current and in series for voltage.

The small finger is to help operate at resonance.

Here is the circuit...... Now what about that Best Answer ?

Spark pump punches holes into paper you can see.

Sorry those thin discs are sound or sensors only.

These power piezo discs and cylinders are the way to go for power generation.

They work both ways, Deform them like the spark pump and you generate electrical Power OR apply voltage to them and they change length (width) enough to activate a mech ratchet (what would you say to a half inch car jack)

That car jack is a 1/2" tube within a second tube and a ratchet to maintain the raised weight of a car. BTW you need an AC to DC bridge because when you deform compress the crystal you get one polarity when you release the force and the crystal is allowed to reform to the original shape you get the other polarity..

Placing a capacitor on the DC side of the bridge will save (No Need of) the application of any safety circuitry because the voltage NEVER exceeds the capacitor design.....

I'm not sure how much usable power you can get out of a few small piezoelectric transducers like that. It would probably require like week of lots of walking and running to get enough power to charge a really small thing. My guess is that while running, you will get the average power that a calculator solar cell generates under standard household lighting. Although I don't know.

However, with the right type of element that can really be compressed and flexed a lot, you can probably get some respectable power output, like that link below:

No answer unfortunately, but I like your idea and could bet that's going to a contest or two as well, so good luck!
