Abstract

In this study, the optimization of piezoelectric materials for good conductivity to measure medical recordings was investigated. For comparison, piezoelectric materials were employed. The analysis is done based on the piezoelectric materials such as lead zirconate titanate, polyvinylidene fluoride, graphene, barium titanate, combination of lead zirconate titanate with barium titanate and graphene, and combination of polyvinylidene fluoride with barium titanate and graphene. COMSOL Multiphysics 5.6 is used to carry out the simulations using different combinations of piezoelectric materials. The stress factor with displacement, electric potential, Young’s modulus owing to different loads were evaluated for different piezoelectric materials. Load variations were performed from 1 to 3 N to plot the interpolated graph. For various loadings, the output revealed good sensitivity for graphene and polyvinylidene fluoride with graphene. The dynamic area in this paper was carried out based on graphene piezoelectric material. With the applied pressure in the range 1–3 N, the final values were obtained from simulation results for PVDF with graphene material with stress factor of 4.52 MPa, the Young’s modulus value as 4.4 MPa, the electric potential obtained in the range of 3–5 µV when compared to other piezoelectric materials involved under study.
