Summary:This paper described a novel use of textile sensors incorporating single-mode hetero-core optical fiber for blood pressure estimation. The textile sensors were designed by weaving hetero-core optical fibers together with wool yarn. The sensor detecting the applied pressure can be integrated into a garment. Textiles, which are fabrics like clothing, are innovative sensors that do not cause stress to the subject. In this paper, pulse wave detection was performed using smart textiles, and pulse waveforms were acquired at the wrist and elbow. We estimated blood pressure for two subjects using the Pulse Transit Time (PTT) method and found that the results were comparable to those of a reference sphygmomanometer. With this smart textile, sensor functions can be embedded in clothing, making it possible to measure blood pressure.
