This part of the charge integration method for measuring pyroelectric coefficient of pyroelectric material.
The method by measuring the pyroelectric charge accumulated in the integrating capacitor, measuring the residual polarization changes with temperature. Electrostatic measurement
The amount of the voltage across the integrating capacitor, recording the measured voltage value due to the capacitance value of the integrating capacitor is much larger than the capacitance value of the sample, both ends
The change in specimen remanent polarization is proportional to the voltage change. At the same time, record the temperature change of the measured values \u200b\u200bobtained pyroelectric charge (Q) with temperature
(T) curve changes, the differential curve can be obtained pyroelectric coefficient at different temperatures. Test shown in Figure 1.

Where.
ΔV0 --- change in output voltage in volts (V);
Change [Delta] Pr --- remanent polarization, in units of coulombs per square centimeter (C/cm2);
Sample A --- electrode area, in units of square cm (cm2 for);
The capacitance value of the integrating capacitor C1 --- farads (F).
Measurement was V0-T curve, find the temperature (T) at a slope that was pyroelectric coefficient, see formula (2).
