Abstract: In this study we analysis piezoelectric materials such as (i)Lead zirconate titanate (ii) Polyvinylidene fluoride (iii) Graphene (iv) Barium titanate (v) Combination of Lead zirconate titanate with Barium titanate and Graphene, (vii) Combination of Polyvinylidene fluoride with Barium titanate and Graphene.COMSOL Multiphysics 5.6(one of the simulation tools) is used to carry out the simulations with different combinations of piezoelectric materials.The stress factor with displacement, electric potential, Young's modulus, and interpolation owing to different loads were evaluated for different piezoelectric materials.According to the findings using COMSOL Multiphysics, the Graphene material delivered better results, so employed for sensor design to get the recordings of Electronic Fetal Electrocardiogram monitoring, Electrocardiogram and uterine contractions for pregnant women.Load variations were performed from 1N to 3N to plot the interpolated graph.The output revealed good sensitivity for Graphene and Polyvinylidene fluoride with Graphene.The simulation results for PVDF with Graphene material were in the range of 200 mm to 500 mm for interpolation plot of different time span and stress factor of 4.52 Mpa ,the Young's modulus value as 4.4Mpa, the electric potential obtained in the range of 300 V to 500 V when compared to other piezoelectric materials involved under study.
