Literature Survey on Smart Optical Fiber based Respiratory Monitoring system

Electronics and communication engineering

Respiration is a significant physiological activity, and internet-based respiration monitoring is of utmost significance in clinical and wearable healthcare applications. Conventional respiratory sensors are actually so problematic that they induce distress, rigidity, signal distortion, and electromagnetic interference, especially in sensitive applications. To address such problems, the application of optical fiber sensors, namely plastic optical fiber (POF) sensors, has proven to be a highly viable solution since they are flexible, lightweight, and immune to electrical noise. They are integrated into wearable garments, elastic bands, and even hospitals requiring non-electrical solutions. The current review provides a general overview of the different fiber-based respiratory sensing technologies, evaluating their structural geometries, sensing modes, and processing schemes. Smart textile advances, wave-structured fiber geometries, and low-cost fabrication of sensors are also addressed in this paper.
