Smart Monitoring of Vital Sign Parameters in IoT-Based Fiber Bragg Grating Sensing Technology

The adaptation of Internet of Things (IoT) technologies in healthcare applications is growing rapidly over the globe. Keeping track of vital sign parameters act as an early diagnosis tool for various diseases. Further, the optical sensing technologies integrated with IoT-enabled systems can solve various healthcare diagnosis requirements. In this article, the intervention of Fiber Bragg Grating (FBG) sensors to effectively monitor vital cardiac parameters and present diagnosis reports using an innovative approach are discussed. The design and construction of a Fiber Bragg Grating sensor are also discussed in the methodology section of the article. Also, the recorded raw Ballistocardiogram (BCG) signal is filtered using advanced filtering algorithms. The heart rate (HR) of different subjects is evaluated in real time after successful filtering of the noisy cardiac signature.
