“…With the consistent rise in the applications of MPA’s in the biomedical sector, these implantable devices do have the capability to integrate with emerging technologies like AI, machine learning, digital twins, augmented reality and virtual reality to achieve excellence in the field. Singh and Barwar (2022) established a set of conformal sensors [Figure 2(a)] through 3D printing with certain combinations of meta-structures and outlined that the sensor printed with the parametric setting: infill density – 75%, raster angle – 0° and infill pattern – a combination of tri-hexagon, gyroid and octet [Figure 2(b)] results in improved dielectric properties with minimum insertion losses on performing the conformal test. Through 3D printing with a combination of meta structures, the developed sensor undergoes more amount of elastic deformation with the combination tri-hexagon-gyroid-octet (T-G-O) and is hence suitable for applications like scaffolding and implant fabrication.…”

Purpose Some studies have been reported in the past on diaphragmatic hernia (DH) surgery techniques using additive manufacturing (AM) technologies, symptoms of a hernia and post-surgery complications. But hitherto little has been reported on bibliographic analysis (BA) for health monitoring of bovine post-DH surgery for long-term management. Based on BA, this study aims to explore the sensor fabrication integrated with innovative AM technologies for health monitoring assistance of bovines post-DH surgery. Design/methodology/approach A BA based on the data extracted through the Web of Science database was performed using bibliometric tools (R-Studio and Biblioshiny). Findings After going through the BA and a case study, this review provides information on various 3D-printed meshes used over the sutured site and available Internet of Things-based solutions to prevent the recurrence of DH. Originality/value Research gaps exist for 3D-printed conformal sensors for health monitoring of bovine post-DH surgery.

Diaphragmatic hernia (DH) recurrence is a commonly reported disorder among bovines. Recently, studies have been reported using wireless devices (like ultrasonic and radio-frequency (RF) based pressure sensors) to detect DH. But hitherto, little has been reported on using polyvinylidene fluoride (PVDF)-based sensors mounted on the diaphragm of bovine to detect the recurrence of the DH post-surgery. In this work, the PVDF-hydroxyapatite (HAP)- chitosan (CS) composite in the proportion of 90-8-2 (wt.%) was used as a substrate for sensor fabrication based on microstrip patch antenna (MPA). Based on the results, the parts of the sensor, that is, substrate, patch, and the ground plane, were designed in the high-frequency structural simulation (HFSS) software assigned with the material properties of PVDF-HAP-CS (as substrate) and 17-4 precipitated hardened (PH) stainless steel (SS) alloy (as patch or ground plane). Upon simulation, it was observed that some deviation in resonance frequency occurred with/ without the natural bovine diaphragm, which was verified based on experimental analysis. The parts were 3D printed for validation through material extrusion (MEX) and direct metal laser sintering (DMLS) processes. Upon testing using a vector network analyzer (VNA), it was observed that the sensor without the diaphragm resonated at 3036.57 MHz with a return loss (S11) of −12.81 dB, whereas the sensor with the diaphragm resonated at 2019.35 MHz with an S11 of −21.06 dB. This shift in frequency with/without the diaphragm is measurable in the industrial, scientific, and medical (ISM) frequency band on a Bluetooth device to detect the reoccurrence of DH.
