| Outline of Final Research Achievements |
We studied a wireless power transmission technology (wireless power processing technology) that freely supplies power to target devices via wireless pulse signals, and an environmental recognition technology based on sensor data to which no positional attribute is assigned (position information non-use type environmental recognition technology). For the former, a method for supplying power to multiple devices located within a line-of-sight while freely changing the beam direction was studied, and for the latter, certain prospects were obtained for realizing a system that is robust to load fluctuations and positional deviation. For the environment recognition technology that does not use location information, the basic principle of operation was devised and its performance was confirmed through simulations and experiments on actual equipment.

| Academic Significance and Societal Importance of the Research Achievements |
センサが収集するデータを介して現実空間を認識し，現実空間とインターネット上の仮想空間とを融合させて社会的課題の解決を図るSociety5.0は，低環境負荷（低消費電力）な技術として実現させる必要がある．本研究で取り上げた無線パワープロセッシングと位置情報非利用型環境認識は，その実現に向けて核となる技術であるが，国内外での過去の検討例が乏しく，社会的意義の高い研究テーマである．本研究の成果は27件の査読付き論文（IEEE Access 5件，IEEE Open Journal of the Communications Society 2件を含む）に掲載され，その学術的意義は高いと認識する．
