Performance Analysis of Polyvinylidene Fluoride (PVDF) Type Piezoelectric Pressure Sensor

This paper reports the design, modelling and simulation of a PVDF based piezoelectric pressure sensor, since PVDF is a semi- crystalline compound and its β phase is most responsive on piezoelectric polymers. The electro-mechanical properties show that the sensor exhibits excellent output response such as Voltage. The output voltage and the applied pressure possess linear relationship with a slope. Design and modeling of the sensor has been carried out using COMSOL Multiphysics. Later, characterization of the fabricated sensor undertaken to examine the parameters of the model and to validate it with simulation and theoretical results obtained, which can be further used for any specific application required.
