The market for automated BP measuring devices is growing
rapidly. Home blood pressure measurement (HBPM) is
becoming more and more popular [5]. The study of G. Bobrie
and others [6] indicated that BP should systematically be
measured at home in patients receiving treatment for
hypertension. With the advances in technology and health
awareness, many researchers use sensor and network
technologies for home health monitoring system. In order to
achieve monitoring of everywhere in home environment, J. H.
Shin and others [7] used the non-invasive sensor to
implement a homecare monitoring system for ECG and PPG
monitoring, whether sleeping on the bed, sitting on sofa, and
even in toilet.
