Towards a Complete Gait Analysis using Optical Fiber Bragg Gratings

Design, Implementation, and Performance Evaluation of a Fiber Bragg Gratings (Fbg) Based Smart Insole to Measure Plantar Pressure and Temperature

“…So, while measuring temperature, the effect of pressure is required to be compensated and viceversa. But from the literature [26,29,31], it has been found that the effect of pressure on temperature is negligible, but the opposite is significant. To understand the effect of temperature on pressure for the cables used for our experiment, we recorded the change in strain reading while applying temperature.…”

“…The developed solution had four FBG sensors spread intelligently around the insole surface. In another of their study [29], they proposed a complete gait monitoring solution consisting of an insole for gait cycle measurements and two additional systems for concurrently monitoring knee and ankle movements using FBG. Each insole contained four FBG sensing units while knee and ankle movements were monitored using a single FBG sensor.…”
