N2 - As instances of heart failure increase globally, total artificial hearts (TAHs) represent a critical bridge-to-transplant technology. However, current TAH systems rely on percutaneous drivelines that significantly increase infection risk and negatively impact patient quality of life. This paper presents the design, simulation and initial results of a wireless power transfer (WPT) system intended for TAH applications, developed as part of an international heart hackathon student competition. The system achieves 30 W of continuous power transfer at efficiencies up to 67 % through tissue-equivalent phantoms, with an implanted coil volume of only 1.4 cm3, yielding a volumetric power density of 21 W/cm3, rivalling or outperforming previously reported systems. We discuss the key engineering challenges, design considerations, and system specifications necessary for practical implementation of WPT in TAH applications.
