Abstract
We developed a chair-attached, nonintrusive photoplethysmogram
(PPG)measuring system for everyday life, unconstrained monitoring
using nonskin-contacting sensor-amplifier circuits capable of emitting
suitable light intensity adaptable to clothing characteristics. Comparison
between proposed and conventional systems showed reasonable correlation
and root-mean-squared error levels, indicating its feasibility for unconstrained
PPG monitoring.
