| Outline of Final Research Achievements |
This is the first breakthrough for exploiting PDMS based freestanding nanosheet skin patch consists of pH sensing elements (antimony/antimony oxide & silver/silver iodate) to achieve high pH sensitivity and repeatability for heatstroke detection. The sensing elements were investigated for its structural and morphological properties. Easy to use and easy to fabricate nanosheet sensor exhibited a linear pH response of -43 mV/pH. Overall, the developed sensor showed high sensitivity, repeatability and stability. Our initial results indicate that the developed sensor well adhered to a skin surface. It is expected that this proof of concept approach gives reliable fabrication and measurement unlike other physical sensors.

隠れ熱中症の最も支配的な要因は、細胞外液の浸透圧とpHの関係からも、明らかな脱水症状である。したがって、固体電極とナノシートで構成された貼付型熱中症フレキシブルセンサの開発により、脱水症状をより直接的かつ連続的にpHを測定できるようになれば、体表面でのpH変化と体温の連続測定により、今まで未知であったpHと温度との相関を深く理解することができ、隠れ熱中症を理解する上で学術的意義も大きい。本研究により、体表面に「貼る」フレキシブル性を持ったセンサで隠れ熱中症の進行具合を知ることができ、高齢者や児童だけでなく全ての年代の人にとって福音となる。
