Wearing type foot health measuring method

Abstract

The invention discloses a wearing type foot health measuring method, which belongs to the technical field of sensing. Sensors which are arranged in an insole (or a sole) are used for sensing physical quantity of a foot of a user when the foot of the user moves, a fiber bragg grating demodulating system placed outside a shoe (or the insole) realizes data processing, and a display terminal has a displaying function. The sensors are packaged fiber bragg grating sensors or Fabry-Perot fiber bragg grating sensors, wavelengths of transmitted waves of fiber bragging gratings can be drifted when the foot of the user moves, optical signals are transmitted to the demodulating system placed outside the shoe (the insole) via optical fibers, the fiber bragg grating demodulating system obtains variation values of the wavelengths of the transmitted waves of the fiber bragg gratings and analyzes and processes signal data, variation of the physical quantity generated when the foot of the user moves can be reflected in due time, and the data can be transmitted to the display terminal to be displayed and realize follow-up processing. The wearing type foot health measuring method has the advantages of simple structure, convenience in manufacture, fast response speed, stability in working, electromagnetic interference resistance, corrosion resistance, high temperature resistance and the like, can be applied in industries including medical treatment, exercise training, games and the like, and has a high practical value.

AI Technical Summary

Problems solved by technology

Piezoelectric sensors are generally thin-film materials with weak signal response, are easily affected by surrounding environmental factors, and have a low signal-to-noise ratio. Therefore, their test accuracy is slightly worse than that of resistive sensors, and they are not suitable for densely arranged sensor arrays.

The capacitive pressure sensor is represented by the German Pedar insole pressure system. This design method is relatively difficult, and the calibration of the capacitive signal and the circuit are relatively complicated.
