title: Multi-channel measurement of photo-plethysmography and evaluation for the optimal site of a thigh in a toilet.
abstract: It is hard to obtain the physiological signals from the thigh. In this study, we used multi-channel photo-plethysmography systems and monitored the signals to know the optimal sites. For the reliability, 8 subjects were participated in the study, and the estimations of probability about their obtained signals were done. With bluetooth technique, we made a remote monitoring don Finally, we chose the candidate sites for the optimal sites and our study will be continued to monitoring the noninvasive and nonconscious physiological signals with this information.
