| Outline of Final Research Achievements |
Optimal installing conditions for measuring radial artery strain with a optical fiber type strain sensor were verified. The experimental results showed that when the sensor was installed within ±5 mm in the direction of the radial artery at from the pulsation point a pressure of 10-15 kPa, a pulsation strain signal with a high signal-to-noise ratio was measured. As an installation method of the sensor to the body, a wristband was developed in which an optical fiber sensor was embedded on a ribbon fabric in the form of a wave with a period of 50 mm. This wristband was elastic and could follow the movement of the wrist as it moved. Therefore, the sensor could be always installed at the pulsation point. From these results, the optimal sensor installation point and the development of a textile product to which the sensor can be installed have been achieved.

生体情報を知るためには生体から発せられる信号を計測する必要があり，生体と常に付着する衣服は生体情報センサとして最も有効である．生体情報であるバイタルサインのうち脈拍数や血圧は循環器の情報であり，血糖値も重要なサインである．そこで，手首の脈動ひずみから循環器の情報を測定するためのセンサ開発として，最適なセンサ設置方法およびセンサを含む繊維製品の開発を進めた．本研究の結果，最適なセンサ設置条件が明確になりセンサを含む繊維製品化が開発されたことから，日々の生体情報を容易に計測することが可能となり，健康寿命延伸に貢献できることが期待される．
