چکیده
Recently, the number of health-related car accidents in Japan has been increasing. Most health conditions leading to traffic are detectable by analyzing fluctuation blood pressure. In addition, cardiopulmonary arrest is an important condition that linked and should be studied along with respiration. Therefore, this study proposes a noncontact measurement system for cardiac dynamics respiration using coupled capacitance electrode. The principle electrode utilizes capacitive coupling human body. body, particular heart lung, regarded as dielectric. displacement dielectric indicated changes To validate proposed system, we conducted measurements concurrent chest circumference strain gauge electrocardiographic recording references. results revealed capable measuring dynamics.
