Simulation and Experiment of PVDF Temperature Sensor

Pyroelectric sensors based on PVDF polymers have great potentialities in the practical areas because of their great merits in the high converting efficiency from caloric or kinetic energy to the electric signal, as well as light-weight and flexibility. This work emphasized on the simulation of the PVDF pyroelectric sensor on the circuit level. The presented equivalent circuit model was simulated with the combination of the whole testing circuit in the environment of Multisim, so the simulated data could be comparable with the measured ones. And the validity of this PVDF sensor’s Multisim model was testified by the comparison with experimental data. Moreover, thermoelectric energy conversion was discussed by the extracted parameters in the equivalent circuit.
