The advent of the smartphone, a compact but powerful and multifunctional computing device, permits the measurements of various physiological indices using a commercially available device alone. This is achieved by using built-in flash LED as a light source and built-in CMOS camera as a photo detector, and is called smartphone photoplethysmography (PPG). Although smartphone PPG is so easy that even a non-specialist can operate by oneself in daily life, it should be used with sufficient knowledge of its effectiveness and limitation. Otherwise, users may encounter unpredictable pitfalls. In this review article, we describe the basics of smartphone PPG in terms of the general background of PPG, restrictions especially for smartphone PPG, and caution during measurement, which are essential information for effective daily life measurement.

緑色の光で脈拍を測る仕組み:なるほど・・・ https://t.co/lJi9LSuZBK
え、どうやってスマートフォンでアドレナリン分泌量測るの??と思ったら、「光電容積脈波測定」なる手法があるらしい https://t.co/3JllReG5a2 「脈の強さ」=「吸光度の直流成分と交流成分の比」がアドレナリン分泌量で鋭敏に変化することを利用しているとか書いてある https://t.co/Owtp3M7D3t
