Outline of Research at the Start

体内埋め込み型センサや医療機器の制御を行うため、電力と信号を同時に伝送するWireless PowerTransfer (WPT)システムは必要とされるが、従来は、信号と電力の伝送のために別々のモジュールが使用されている。本研究では、小型化マルチバンドWPTによる信号と電力が同時伝送される単一モジュールを開発し、電力をMulti-Sine波で伝送し、受信機と整流回路間は、生体の電気特性を考慮した複数共役インピーダンスマチィング技術にて小型化マルチバンドWPTシステムで体内への伝送効率を向上する手法を提案する。最終的に、体内への信号の伝送効率(AC-AC)を80%と電力のAC-DC効率を50%以上の小型化WPTシステムを開発する。

Outline of Annual Research Achievements

In this joint research, we were able to make the so-called artificial dielectrics having negative permeability which is also known as metamaterial that will work for nearfield WPT system. We proposed the condition for such metamaterial, and we also proposed a new type of metamaterial in 3D configuration to satisfy these conditions. We also proposed a single compact and high-efficiency WPT system that can transfer the power and signal concurrently to biomedical implants or embedded medical devices. In the collaborative work, many ideas were invented jointly, and some of them by the host researchers and implemented by the JSPS fellow in a concise period remarkably and effectively. The results were published in many highly referred transactions and international conferences/symposium.We publisehd three works. In Work 1 where simultaneous wireless power and information transfer system using coupled co-existing defected ground structures. In Work 2 where simultaneous wireless power and information transfer system using coupled co-existing defected ground structures and figure-8 inductors is proposed realized. In work 3 where new type of metasurface-inspired geometry was proposed for compact WPT system for biomedical applications. In this study, a new type of metasurface with the stacked configuration is proposed to make it more compact and easy to integrate with the receiver.
