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. © 2010 Wiley Periodicals, Inc.
