“…In addition, the difference in peak power loss in sample 7 which is farther from the other samples is because the fiber optic belt responds more to the large abdominal circumference during inhalation. The further the belt moves during inhalation, the higher the power loss value [26]- [28]. This fiber optic belt actually relies on the principle of strain and stress from the buffer that forms the SMF and FBG in a sinusoidal pattern.…”

Optical fiber is increasingly popular and appreciated as a modern sensor technology in various sectors, one of which is for medical functions. This study was conducted to detect human diaphragmatic breathing flow using theoretical and experimental approaches. Initially, the lung model was formed using the finite element method and the Navier-Stokes equation by applying the principles of momentum and continuity. Furthermore, fiber Bragg grating (FBG) and single mode fiber (SMF) were experimentally designed with sinusoidal patterned macro-scale bending as a stretch sensor in a breathing belt applied to the diaphragm. The simulation model shows the airflow velocity increases up to 4 m/s when it flows into smaller branches. While the experimental results show that the largest power loss occurs at a buffer diameter of 0.8 cm. The power loss detected in SMF is a maximum of -0.18 dBm during inhalation and a minimum of -0.28 dBm during expiration. However, FBG bending is superior with high sensitivity.

“…9 Compared with traditional electronic sensors, optical fiber sensors offer advantages such as small size, light weight, low cost, and immunity to electromagnetic interference. [10][11][12][13] Polymer optical fiber (POF) sensors are widely used due to their higher flexibility and lower Young's modulus for fabric sensors. 14,15 Conventional POF fabric (PF) sensors for monitoring the pulse and SpO2 are mostly based on embroidery technology or fixing POFs with chemical materials.…”

Monitoring pulse and arterial oxygen saturation (SpO2) continuously and in real-time is conducive to the prevention and monitoring of cardiovascular disease. The reported optical fiber fabrics have the shortcomings of low side-emitting and side-coupling efficiency of a single fiber, and more optical fibers were used. In this paper, we propose a micro-bending bulge structure based on side-emitting and side-coupling of the polymer optical fiber (POF), and a small number of the POFs are woven into the fabric as weft yarns to measure pulse and SpO2 using a simple plain weave. The experiments investigated the effect of the different micro-bending bulge structures on the side-emitting and side-coupling efficiencies by means of the ray tracing method, explored the feasibility to measure pulse waves and SpO2 on the fingertip, brachial artery, and forehead ophryon, and evaluated the accuracy of the measurements in the static, dynamic, and sweating states. The results show that the side-emitting and side-coupling efficiencies of the POF are optimal by adopting a 1 mm micro-bending bulge height and a 3 mm micro-bending bulge width. The fabric sensor with three side-emitting POFs and two side-coupling POFs is capable of monitoring pulse and SpO2 on the forehead. In addition, the maximum error is 1 bpm for the pulse and within 2% for SpO2 on the forehead.
