Development of an in-shoe pressure-sensitive device for gait analysis.

Area of Science:

• Biomechanics
• Wearable Technology
• Biomedical Engineering

Background:

• Gait analysis is crucial for understanding locomotion and diagnosing movement disorders.
• Accurate plantar pressure measurement is essential for detailed gait analysis.
• Existing methods may lack portability or high-frequency data acquisition capabilities.

Purpose of the Study:

• To develop and characterize a novel in-shoe device for monitoring plantar pressure distribution.
• To enable high-frequency data acquisition and wireless transmission for gait analysis.
• To perform a preliminary validation of the device on a healthy subject.

Main Methods:

• Integration of a 64-element sensor matrix within an in-shoe system.
• Incorporation of in-shoe electronics and a battery for autonomous operation.
• Experimental characterization and preliminary in-vivo testing for gait analysis.

Main Results:

• The developed in-shoe device successfully captures plantar pressure distribution data.
• The system supports high-frequency data acquisition and wireless transmission.
• The device demonstrated an average autonomy of 7 hours in continuous use.

Conclusions:

• The developed in-shoe plantar pressure monitoring device is a viable tool for gait analysis.
• The system offers portability, high-frequency data, and sufficient battery life for practical applications.
• Preliminary validation suggests potential for use in clinical and research settings.
