  • BLOOD-PRESSURE SENSOR, MANUFACTURING METHOD THEREOF, AND BLOOD-PRESSURE SENSOR SYSTEM
    Publication number: 20110152694
    Abstract: A blood-pressure sensor is constituted of an elastic body which is fitted to a blood-vessel outer wall, and a shape of which is deformed by force generated by pulsing motion of expansion and contraction of the blood vessel, and a plurality of nanosized particles dispersedly provided in the elastic body, and when the force is applied to the sensor in a state where the sensor is irradiated with light, the magnitude of the force is measured on the basis of intensity of scattered light from the particles or emission intensity of fluorescence from the particles, the intensity of the scattered light or emission intensity of the fluorescence corresponding to a change in distance between the particles.
