“…However, they may exhibit non-linearity and sometimes a significant hysteresis [ 26 , 30 ]; fiber optic sensors: typically produced in a polymer (POF, Polymer Optical Fiber; PMDS, Polydimethylsiloxane), fiber optic sensors consist of a light emitter and a light receiver with a specific wavelength. When the fiber is pressed, the Fiber Bragg Gratings (FBG) sensor measures deformation by varying the photo-elastic constant of the fiber and a change in microstructure period, resulting in a change in Bragg wavelength [ 38 , 50 , [67] , [68] , [69] , [70] , [71] , [72] ]. …”

Gait Pattern Analysis: Integration of a Highly Sensitive Flexible Pressure Sensor on a Wireless Instrumented Insole

“…Consequently, gait analysis is instrumental in biomedical engineering for the investigation of human locomotion. This wide-ranging utility has sparked significant interest among researchers and clinicians alike, to find sensors and instrumentations for gait analysis [3][4][5][6][7]. V. Bucinskas et al devised and constructed a pressure sensor for assessing human gait by examining foot pressure distribution.…”
