Outline of Final Research Achievements

Bilateral masseter electromyograms, mental muscle electromyography, electroencephalogram, electrocardiogram, respiratory movement diagram, eye movement diagram were recorded during nighttime sleep of subjects using a small, lightweight portable device equipped with Bluetooth. Recorded data were displayed, checked and saved using a sensor data display/recording software. An attempt was made to create a program that can display and analyze multiple channels from saved CSV data. It was confirmed that biological phenomenon data during sleep at night could be saved for each two channels. It was confirmed that CSV data for every two channels can be converted into binary data that can display multiple channels at the same time. It was enabled detailed analysis of electromyogram and electrocardiogram.

Academic Significance and Societal Importance of the Research Achievements

Bluetooth搭載小型軽量のポータブル装置を用いて、被験者の夜間睡眠中の両側咬筋筋電図、オトガイ筋筋電図、脳電図、心電図、呼吸運動図、眼球運動図の記録とCSVデータの表示が行えた。保存したCSVデータをテキスト・バイナリファイル変換プログラムを用いると、バイナリデータ（DATデータ）に変換が可能であり、その結果、生体現象の詳細な解析が可能となり、臨床応用できる可能性があることが示唆された。
