Development of non-invasive and ambulatory physiological monitoring systems for ubiquitous health care

Ubiquitous healthcare is very important subject not only as an effective scheme for early diagnosis of cardiovascular and other diseases, but also for prevention and control of such diseases. For this purpose, we have developed two kinds of non-invasive physiological monitoring systems. One is the systems utilizing furniture and furnishings in home to detect biosignals under daily life, and the other is portable systems for ambulatory monitoring of physiological valuables including blood pressure, cardiac output, posture change, walking speed, and so on.. In this paper, structure and performance of these systems are briefly described.
