Outline of Final Research Achievements

AE sensor that can adhere even to a complex shaped stem and can detect plant AE was developed and demonstrated that it can detect plant AE regardless of the size and hardness of the stem to which it is attached. Stand-alone AE device combined with solar cells and batteries was developed. Then, IoP device that can measure plant AE anytime and anywhere demonstrated that plant AE can be measured for a long period of time without power supply. Furthermore, by visualizing plant AE occurence behavior and environmental changes, we monitored plant activity and quantified the environmental impact of plants, thereby clarifying the usefulness of activity monitoring using plant AE.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、植物のさまざまな部位にAEセンサ(ECS)を取り付けられ、いつでもどこでも活動モニタリングの根幹となるAEデータが常時計測（植物の活動モニタリング）できるようになるAE発生数の挙動は、植物の活動状態を視覚的に理解しやすいデータであり、様々な場所における活動モニタリング情報を共有し、環境との関連を探ることで、環境影響評価としての利用を促進できる。
