Outline of Final Research Achievements	We conducted research on wireless charging for medical devices and simultaneously developed medical devices and communication networks suitable for remote areas and home healthcare. In response to the global pandemic of the novel coronavirus, we created an improved prototype machine to assist patients undergoing home-based treatment. The improved machine was exhibited at the Tokushima Invention Association and received the Tokushima City Mayor's Award. In the study on wireless charging using gallium nitride (GaN) semiconductors, we successfully obtained patent rights both domestically and internationally. Our experiments in the radio wave shield room achieved successful transmission at a distance of approximately 2 meters. Additionally, in 2019, our research was the sole selection from Tokushima Prefecture at the European Society of Anaesthesiology, where we presented our research findings. As a result, our research garnered attention both domestically and internationally.
Free Research Field	臨床工学
Academic Significance and Societal Importance of the Research Achievements	新型コロナウイルス感染症に罹患し在宅療養する患者に役立てるため、改良プロトタイプ機を作成し、この改良機が徳島県発明協会で徳島市長賞の受賞につながったことは、本件研究の注目度の高さと社会的貢献度に期待がされていることに改めて気づかされることとなった。また、ワイヤレス給電に関する研究においては、レクテナアンテナに使用した窒化ガリウム半導体の製法について、国内外と合わせて４か国で特許を取得できたことは、我が国の半導体分野での研究の復活の狼煙となることが期待される。
