| Outline of Final Research Achievements |
From the fingertip, we developed a system to detect increase and decrease in blood volume with pulsation with a USB camera, display it as a pulse wave, and quantify it. We verified that the obtained pulse wave is data reflecting biological information.
We developed a software by Processing that automates various kinds of processing, and teaching materials that peak detection, resampling, Fourier transform by numerical data processing outputted by developed software. We developed a pulse wave device at 2 ms intervals and verified the relationship between fluctuation and autonomic nerve function. A respiratory rate detector was prepared and the relationship with respiration rate fluctuation was investigated. We verified that the pulse wave is an observation quantity which has useful meaning as biological information. We conducted eight practical lessons using teaching materials.
