On 3D printed intelligent diaphragmatic hernia sensor

Abstract

Purpose The purpose of this paper is to design and manufacture an intelligent 3D printed sensor to monitor the re-occurrence of diaphragmatic hernia (DH; after surgery) in bovines as an Internet of Things (IOT)-based solution. Design/methodology/approach The approach used in this study is based on a bibliographic analysis for the re-occurrence of DH in the bovine after surgery. Using SolidWorks and ANSYS, the computer-aided design model of the implant was 3D printed based on literature and discussions on surgical techniques with a veterinarian. To ensure the error-proof design, load test and strain–stress rate analyses with boundary distortion have been carried out for the implant sub-assembly. Findings An innovative IOT-based additive manufacturing solution has been presented for the construction of a mesh-type sensor (for the health monitoring of bovine after surgery). Originality/value An innovative mesh-type sensor has been fabricated by integration of metal and polymer 3D printing (comprising 17–4 precipitate hardened stainless steel and polyvinylidene fluoride-hydroxyapatite-chitosan) without sacrificing strength and specific absorption ratio value.

3D-printed conformal sensors for health monitoring of bovine post diaphragmatic hernia surgery: a review

“…The study dealt with the materials PVDF-HAP-CS and 17-4 PH SS that are biocompatible, piezoelectric (PVDF) and durable. According to previous studies, the implant made up of these materials would last approximately 15 years (Singh et al , 2023a, 2023b, 2023c), whereas the life of the targeted patient is only 10–12 years, therefore these materials bring sensing capabilities along with good mechanical properties. For the durability of the implantable sensors, essential factors are pore size, flexibility and mechanical properties of the hernia mesh as well as the incorporation with host tissue, and the selected materials are suitable for such applications (Singh et al , 2023a, 2023b, 2023c).…”

The low durability of PP solely depends upon its semicrystalline nature, which is responsible for the warpage and shrinkage behavior of PP that indirectly affects the mechanical strength of the component (Zander et al , 2019), whereas poor flowability and high viscosity make PTFE a difficult to extrude material.…”

“…Ti-based alloys are the most used materials for biomedical applications because of their corrosion resistance, good mechanical properties, etc. (Hosseini et al , 2016; Singh et al , 2023a, 2023b, 2023c) provide an innovative design of multi-rooted dental implants for the strategic tooth of canines through the DMLS process using SS alloy. Apart from implant and prosthetic fabrication, AM also found an effective application in the field of biosensors that can transmit a physiological signal from the patient’s body to a smart device for health monitoring purposes (Moscato et al , 2016).…”
