| Outline of Final Research Achievements |
As the number of people living in institutions continues to increase in our super-aged society, the increased risk of bone fractures and dementia associated with vitamin D deficiency have become major issues. In this study, we developed a system that measures individual UV exposure in real-time using a wireless UV sensor attached to any part of the body, and notifies the user via Smartphone of the optimal UV dose required to produce vitamin D in the blood. This application, which is currently undergoing data collection and accuracy improvement, is a completely new attempt to avoid excessive UV exposure and to take (expose) the necessary amount of UV light.

| Academic Significance and Societal Importance of the Research Achievements |
日常生活におけるUVの適切な皮膚曝露はビタミンD生成を行う一方，過剰な曝露は様々な皮膚疾患を引き起こすことが報告されている．しかしこれら有益・有害の線引き，いわゆるUV至適量は未だ不明である．本研究はこのUV至適量推定に資するデバイスの開発およびUV至適量通知システムの構築を目的とした．同システムの実現は，過剰なUV曝露を避けつつ，必要量を摂取（曝露）する一次予防の一助となる可能性を有し，日本人の健康増進に大きな貢献を行うものと考えた．
