A method for measuring pyroelectric coefficient (p[subscript 3]) of polyvinylidene fluoride (PVDF) films was developed. Light pulses of 10 Hz frequency were exposed on two samples of PVDF films of 30 micrometre thickness. Three different light intensities were used for each set of measurement. A lock-in amplifier was used to measure voltage pulses from PVDF electrodes. An electrometer was used to measure the increase in the resistance of PVDF electrode when the films were exposed to light and obtain the increase in the temperature of the films due to the light pulses. From these experiments, the values of p[subscript 3] of the first and second films were found to be in range of (41+-4) to (50+-6) micro C/m[superscript 2] ํC and (4.9+-0.2) to (5.5+-0.5) micro C/m[superscript 2] ํC, respectively. These values are different from the reference values of the film by 15%.
