It is hard to early detect somnipathy such as sudden death (SD), sleep apnea syndrome (SAS), and obstructive sleep apnea (OSA) because the patients don't aware of the subjective symptoms. Then, it is needed to develop a vital-sign monitoring system which can measure the vital signs in a sleep state over the long period. In this paper, we develop a belt type sensor that can measure the signals of respiration, heartbeat, and ECG in a sleep state by using conductive fibers and a Polyvinylidene Fluoride (PVDF). Since the sensor is a belt type, it can be attached with the patients with a minimum invasion. In order to verify the effectiveness of the sensors, we measure not only the signals from the sensors but also that from the commercially available sensors. The results show the validity of our approaches.
