Investigate the optical FBG sensor to monitor the alignment of human body

In recent times, the true potential of Fiber Bragg Grating (FBG) Sensors is discovered that, it can be used to determine the physical parameters of a structure like: Strain, Temperature, corrosion etc. Researchers across the globe has also started to look for the usage of FBG in the healthcare department to monitor the different parameter of human body like blood pressure, glucose level, sugar level heart beat rate etc. Taking the research to its new heights, this research paper proposed the use of FBG optical sensor to monitor the alignment of human body. As it has been observed that when a human suffers from the Spine Dislocation or some other structural imparity, it's one of the major symptoms are the abnormality in walk and uneven strain on feet. If these symptoms detected at initial stage, then the cure is much easier. This paper shows the potential use of Fiber Bragg Grating Sensors to monitor Alignment of Human Body. In the research, two sensors were mounted at the bottom of both the feet of the person. The person walked for a few seconds and the readings of wavelength change due to strain on feet. Experiment was done on 3 persons with sensors mounted at the bottom of their feet and the readings were observed.
