Designing and analyzing multi-coil multi-layers for wireless power transmission in stent restenosis coronary artery

Wireless power transfer technology features shorter transmission distances in biomedical applications. This is a result of the small size implanted coils, biocompatible material conductivity, and large between receiving transmitting coils. There have been numerous attempts to improve efficiency across longer distances. Multiple including 2-, 3-, 4-, multi-layered were previously considered. study proposes novel approach achieve higher by integrating single coil on side three asymmetric coils transmitter side. As such, it delivers sensor within coronary artery that monitors blood pressure while introducing uniquely shaped stent. The transmitted stent its dual forms, helical zigzag helical, was examined as well, with wireless system thereby analyzed at 27 MHz Industrial Scientific Medical band operating frequency. For four-coil technique, distance 25 mm receiver sides using biological human tissue medium can reach 56.42%, whereas other approaches show lower efficiencies: three-coil method’s 32.88%, double-layer parallel 27.75%, two-coil 24.76%, triple-layer 17.31%, series 0.501%, 0.092%. In addition, suggested demonstrated be more efficient than prior designs regard which represent stents.
