摘要

In the past, some studies were reported on the use of different thermoplastics/composites (like porcine pericardium, polyvinylidene fluoride (PVDF), polypropylene (PP), polytetrafluoroethylene (PTFE), etc.) as mesh materials for diaphragmatic hernia (DH) surgery in bovines. However, limited studies have been reported on the sensing capabilities of these materials for detecting foreign body syndrome in bovine post-surgical treatment. To minimize post-DH surgery complications and facilitate remote health monitoring, a PVDF-based composite (90% PVDF, 8% hydroxyapatite (HAP), and 2% chitosan (CS) by weight) has been used in this study for the fabrication of hernia mesh as a substrate for novel biosensors. Rheological, mechanical, morphological, and thermal characterizations were performed on the proposed composite to ascertain its suitability as a biosensor in high-frequency applications. Finally, the sensor was designed using the high-frequency structure simulator (HFSS) and simulated within a phantom model comprising three layers: a diaphragm, a PVDF-based substrate, and a reticulum of bovine tissue. The frequency (fo) vs. insertion loss (S21) characteristic curve indicates that the proposed biosensor can provide signals in the industrial, scientific, and medical (ISM) band, resonating at 2.46 GHz, and is found to be suitable for health monitoring of bovines post-DH surgery.
