| Outline of Final Research Achievements |
In this study, the communication area of the body area network, which was previously limited only to the area around the living body, was expanded to include not only the area around the living body but also the area deep inside the living body. We have clarified the antenna characteristics and transmission characteristics of antennas placed inside and outside the body, and also clarified the electromagnetic compatibility including electromagnetic biosafety. We have further investigated and demonstrated the possibility of making the antenna transparent and of sensing biometric information with a communication antenna, taking into account the wearability of the antenna and the extension of its functionality. The findings obtained through this research are important and effective in solving technical issues such as transmission quality and transmission characteristics of conventional body area communications.

本研究で提案・検討した磁界励振型送受信アンテナによる人体周辺通信は、従来の電界励振型アンテナを利用するものに比べて生体の影響を受けにくい。そのため、生体周囲のみならず生体内部・深部へと拡張し、生体内外を通信エリアとする次世代の新しいボディエリア通信へと発展させることが可能となる。さらに、提案アンテナを利用することで、通信のみならず、センシングが可能であることも発展的に示した。本研究の成果は、健康意識が高まる現代社会において、次世代の通信・センシング機能を両立するデバイス・システム開発の知見として重要かつ有効なものである。
