Area of Science:

  • Biomedical Engineering
  • Materials Science
  • Rehabilitation Technology

Background:

  • Traditional rigid sensors for plantar pressure detection have limitations including poor biocompatibility and high manufacturing costs.
  • Gait disorders require effective monitoring and rehabilitation strategies.
  • Accurate plantar pressure distribution analysis is crucial for understanding and treating gait abnormalities.

Purpose of the Study:

  • To develop a novel flexible sensor array for precise plantar pressure detection and gait pattern recognition.
  • To overcome the limitations of conventional rigid sensors in terms of flexibility and cost.
  • To enhance gait rehabilitation for individuals with gait disorders through advanced sensing technology.

Main Methods:

  • Fabrication of a flexible sensor array using Acrylamide/Sodium chloride (AAM/NaCl) hydrogel and Polyimide (PI) membrane.
  • Characterization of the sensor array's structural flexibility and sensitivity.
  • Implementation of a Wavelet Transform-Random Forest (WT-RF) algorithm for gait recognition based on plantar pressure signals.

Main Results:

  • The developed hydrogel-based sensor array demonstrated excellent structural flexibility (209 KPa) and high sensitivity (12.3 mV·N⁻¹).
  • The sensor array ensures accurate pressure signal collection due to full foot sole contact.
  • The WT-RF algorithm achieved a high gait classification accuracy of 91.9%.

Conclusions:

  • The novel hydrogel flexible sensor array offers a promising, cost-effective, and biocompatible alternative to traditional rigid sensors.
  • Accurate plantar pressure monitoring and gait recognition using the developed system can significantly improve gait rehabilitation outcomes.
  • The integration of advanced signal processing algorithms like WT-RF enables precise gait analysis for clinical applications.
