摘要

Recently, significant studies have been reported on using polyvinylidene fluoride (PVDF) composites for biomedical applications due to its semi-crystalline nature and appreciable dielectric properties. However, little has been reported on using ZnO and lanthanum (La)-doped ZnO as reinforcement in PVDF for enhanced sensing capabilities required for condition monitoring of diaphragmatic hernia (DH) in Bubalus bubalis (BB). This study highlights the design and simulation of PVDF, PVDF-ZnO, and PVDF-La-doped ZnO-based structures for dielectric analysis. It investigates the sensing capabilities of proposed compositions for designing the DH sensors. The results outlined that the PVDF-La doped ZnO with loss factor (ɛ”) of 0.019 (using Debye relaxation model) possesses an acceptable specific absorption rate (SAR) of 1.10 W/kg for the monitoring of DH in BB. The observed insertion loss (S11), resonance frequency (Rf), and SAR value for the proposed composition highlighted that La-doped ZnO reinforced PVDF may be used for 3D printing DH sensors.
