Abstract
An optical fiber arterial pulse wave sensor is proposed using an in-line Michelson interferometer that is a hollow optical fiber spliced to a single-mode fiber at one end and cleaved at the other end. The proposed optical fiber arterial pulse wave sensor consists of an in-line Michelson interferometer and steel reinforcement enclosed in a heat-shrinkable tube. The sensor was directly attached onto a wrist and signals corresponding to arterial pulse waves successfully obtained. The signal-to-noise ratio of the sensor signals was better than 20 dB.
