Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Generated charge (C)

Required number input.

Effective capacitance (F)

Required number input.

Estimate open-circuit piezoelectric voltage as generated charge divided by effective capacitance. Loading, leakage, and amplifier input impedance can reduce measured voltage. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Voltage V

The resulting voltage v returned as a number.

• Piezoelectric charge, voltage, displacement, sensitivity, and resonance depend on material constants, axis, geometry, preload, boundary conditions, frequency, temperature, dielectric loss, amplifier input, and hysteresis. Static measurements are limited by leakage.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Fuel Gauge SOC From Voltage

  Estimate fuel-gauge state of charge by linear interpolation between user-supplied empty and full open-circuit voltages; chemistry, load, and temperature can make this inaccurate.

• Piezo Sensor Charge Amplifier Voltage

  Calculate ideal inverting charge-amplifier output voltage as −Q/Cfeedback for a piezoelectric sensor; leakage and reset circuitry are excluded.

• Battery State Of Health

  Calculate battery state of health as measured full-charge capacity divided by rated new capacity, expressed as a percentage; values over 100% can be valid measurements.
