| 研究実績の概要 |
To enhance both transfer efficiency and received power, our research focuses on developing a Simultaneous Wireless Power and Information Transfer (SWPIT) system tailored for Active Implantable Medical Devices (AIMDs) through a near-field approach. Our aim is to create a high-performance SWPIT prototype optimized through mathematical modeling and physical simulations for the future clinical setting.
Commencing in November of the fiscal year 2023, our research has yielded the following achievements:
1) Near-field electric coupling investigations have identified the optimal frequency band for cardiac AIMD architecture, determined through finite element analysis. We have prepared a conference paper focused on cardiac IMD applications for submission to IEEE BioCAS 2024.
2) Regarding near-field magnetic coupling, an optimization algorithm based on semi-definite relaxation has been derived. This system incorporates a metasurface, and the corresponding prototype is currently being developed. Upon completion, we intend to submit our findings to IEEE Transactions on Power Electronics.
3) For the joint sensing and wireless information transfer, we are positively seeking collaboration opportunities. We have initiated discussions with Dassault Systems, and their Living Heart Project is poised to play a role in this research. Leveraging their model, we aim to conduct multi-physics simulations, enabling comprehensive comparisons with animal experiments conducted at Oslo University Hospital in Norway. The findings could be released in a high-impact journal and even apply for a US patent.

理由
1) The optimal frequency band for cardiac AIMD architecture based on near-field electric coupling has been identified, and the SAR results have been obtained by finite element analysis. 2) A next-generation metasurface-aided wireless power transfer system has been developed. Here, the semi-definite relaxation method has been adopted as an optimization algorithm. 3) The joint sensing and wireless information transfer preparation is ongoing. We can foresee some exciting findings that can be published in a high-impact journal. Until now, one conference paper has been finished, and one journal paper targeting IEEE transactions on power electronics is preparing.

| 今後の研究の推進方策 |
Since the progress is rather smooth, we will follow our prescribed plan to continue our research. In fiscal year 2024, we aim to identify the fundamental trade-off through theoretical analysis and understand how to deliver information and energy simultaneously to a receiver most efficiently. Meanwhile, the results obtained in the fiscal year 2023 will be organized and released as soon as possible. Moreover, we will develop our prototype and further conduct our animal experiment at Oslo University Hospital.
