In recent years, the demands for vital sign measurement system have been increasing, such as home health care for elderly people, or self-health management for healthy people. In this study, we aimed at the development of a non-invasive wearable device to measure vital sign. We use a Fiber Bragg Grating (FBG) sensor as pulse wave sensor. A FBG sensor is the optical fiber. Therefore, a FBG sensor has a lot of features. Its characteristics are suitable for the measurement of vital signs at all times. We fix FBG sensors to different two points of the body surface and acquired pulse wave. We calculated the systolic blood pressure by using Pulse Transit Time (PTT) which is arrival time lag of pulse wave. We have confirmed the validity of the principle of systolic blood pressure measurement by FBG sensors.
