Outline of Final Research Achievements

This research aims to develop a practical healthcare wearable device with terminal-to-terminal communication using magnetically coupled, intra body communication (IBC) by comprehensively resolving the associated technical problems . We analyzed the characteristics of signal transmission loss for various magnetic-field-coupling methods and developed their equivalent circuit models. Based on this analysis, we formulated a guideline to optimize the resonant frequency characteristics of the resonant coupling method. Then, the communication characteristics of all coupling methods were evaluated. Additionally, we examined and evaluated a 2-coil wireless power transmission system to achieve optimum power transmission efficiency. Finally, we fabricated a prototype of a magnetically coupled, IBC-based wearable device. Thus, we obtained multiple results using the designed system. We also evaluated and verified the device safety for applications to living organisms.

Academic Significance and Societal Importance of the Research Achievements

人体通信の伝送方式として磁界を用いた方法に関する研究はほとんど行われておらず,これからの発展可能性が非常に大きい研究課題である.本研究では,ボディエリアネットワーク(BAN)に適用可能な通信方式の中で最も優れた手法となりうる磁界方式人体通信システムの実用化技術に関する各種成果を得ることができた.この実用化技術は,医療・ヘルスケア用BANだけでなく,汎用的な用途(例えばワイヤレスイヤホン等)の通信システムにも適用が可能である.
