Fiber Bragg Gratings based smart insole to measure plantar pressure and temperature

Various foot complications can be easily avoided by continuously monitoring plantar (foot sole) pressure and temperature at home. Systems which simultaneously measure in real time are still scarce. In this work, the design, characterization, implementation of a Fiber Bragg Gratings (FBG) based smart insole capable measuring has been reported. The instrumented was tested verified during static gait exercises. paper also provides comparison developed optoelectronic-based solution with commercially available widely used measurement analysis system, lab-made electronic sensor-based for recording temperature. It shown that even though commercial acquisition system is very robust highly precise due to many sensing units on insole, much smaller number sensors acquire both reasonable precision while displaying maps, cycle plots real-time development cost more than eight times lower manufacturing solution. Our proposed lightweight, uncomplicated but robust, electronically safer system. While far from its optimized form, we expect our prototype will instigate other researchers domain further explore solutions monitoring.
