What is the Piezoelectric Calculator?
Squeeze certain crystals and they spit out electricity — press a barbecue igniter and you have felt it in your thumb. The piezoelectric effect turns force into charge with one tidy rule: the charge generated equals the material's piezoelectric coefficient times the applied force, Q = d × F. Quartz, the crystal in every cheap wristwatch, uses the reverse trick too — feed it voltage and it vibrates at an exact frequency, which is why your watch keeps time.
This calculator runs the charge equation. Type the material's piezoelectric coefficient d₃₃ in coulombs per newton into Variable A — about 2.3 × 10^-12 for quartz, up to 500 × 10^-12 for PZT ceramic — and the applied force in newtons into Variable B. The Result box shows the generated charge in coulombs. A pickup winder in Nashville pressing 10 newtons into a PZT disc, for example, expects about 5 nanocoulombs per squeeze, which the guitar amplifier then turns into sound. Engineers sizing knock sensors, ultrasound probes, and electronic drum triggers all start from this same multiplication.
With the pre-filled defaults — Variable A 10, Variable B 5 — the Piezoelectric Calculator returns Result 50.0000. Change any input and those results update instantly, so you can see exactly how each number you enter moves the answer.
How to Use the Piezoelectric Calculator
- 1Look up your material's piezoelectric coefficient d₃₃ in coulombs per newton and type it into the Variable A box.
- 2Type the mechanical force in newtons into the Variable B box — 10 N is roughly a firm thumb press.
- 3Read the generated electric charge in coulombs from the Result box.
- 4Divide the Result by the crystal's capacitance if you need the voltage the charge will develop.
- 5Stack or wire multiple elements and multiply the Result by the element count for the total charge.
- 6Check whether your datasheet quotes d₃₁ or d₃₃ — the direction of squeeze changes which coefficient applies.

Calculation Progression Roadmap
How the Piezoelectric Calculator turns your inputs into a result, step by step — from the values you type to the answer you read.
Gather your inputs
Type in your Variable A and Variable B. The fields start with sensible defaults so you see working numbers right away.
Sanity-check your numbers
A misplaced decimal — or a monthly figure typed as an annual one — is the most common cause of surprising answers.
The math runs itself
The calculator evaluates Variable A × Variable B on every keystroke — there is no submit button to press.
Read your results
Your Result appears instantly. With the pre-filled defaults, that is Result 50.0000. Change any input to see the effect immediately.
Test a what-if
Try a bigger and a smaller value for one input. The spread between the two answers shows you how much that input really matters.

Frequently Asked Questions
Generated charge equals the piezoelectric coefficient times the applied force: Q = d × F. A bigger squeeze or a livelier crystal material both raise the charge.
