| Outline of Final Research Achievements |
We have developed piezoelectric polylactic acid sensors for vital sensing using traditional craft techniques. In this study, in order to industrialize this handmade technique, we used the finite element method and devised a sewing shape using an industrial sewing machine to achieve the same functionality as the traditional craft technique. This has expanded the possibility of social implementation. Furthermore, the data transmission system using BLE that has been developed in the past had frequent signal loss problems due to the position and posture of the subject, but by thoroughly optimizing the circuit, the performance was dramatically improved. Finally, we were able to verify the accuracy of vital sensing using a sewing sensor with an ingenious stitching technique in the free behavior of a toy poodle, an indoor dog.

伝統的な几帳結びを用いた研究段階だったユニークなバイタルセンシングを、より実用的な工業的手法（ミシン縫いの方法）で実現することが可能になった。この成果は、大量生産可能な産業プロセスに転換する道を開いた。特に、室内犬を対象とした健康管理では、このセンサ技術が、動物の安全と快適を保ちながら連続的な健康モニタリングを可能にする。BLE通信の最適化によるデータ送信の安定化も、リアルタイムでの健康データの確実な受信を保証し、動物医療やペットケア産業における予防医学と早期発見の推進に寄与すると考える。この成果は、将来的には人間にも適用可能なウェアラブルセンサ技術の発展に繋がる一歩である。
