Downsizing of coreless coils for transcutaneous energy transmission in implantable devices - Improvement of coupling factor and efficiency between coils

摘要

Transcutaneous energy transmission is useful for improving patient quality of life and for supplying energy to implantable devices noninvasively. To supply highly efficient energy transmission through the skin, it is necessary to increase the coupling factor between the coils and increase the inductance of each coil. In this study, the optimal shape required for the coils to increase the coupling factor was investigated.
