Outline of Final Research Achievements

The visualization and evaluation systems for human stress and/or emotion have been developed under investigating three viewpoints such as;(1)IoT sensor module for sleep sensing, (2)low-power design of CMOS logic circuits for signal processing system, (3)autonomic nervous system(ANS) evaluation index for visualization of stress/relax state.
It is found that the compact IoT sensing system is effective for evaluating human ANS condition in his daily and sleeping lifetime.

Academic Significance and Societal Importance of the Research Achievements

人間の健康管理を機器の方から積極的に支援するシステムの開発を目指し、普段の何気ない動作の最中に、測定を意識させる事なく生体計測が行えるセンサシステムと、日常の体調データと環境データを基に解析し、健康管理・ストレス管理およびその支援ができるような解析評価技術を開発し、ベッドに眠るだけで入眠／目覚めを支援するセンサーベッドシステムの基盤技術を構築した。超高齢化社会に突入する我が国において社会的意義は大きい。
