Feet Position Identification Using Velostat
摘要
This paper presents a cost-effective solution for foot posture identification using a pressure sensing mat. The mat is constructed with velostat, a carbon-impregnated polyethylene material, as the core sensing element. It features a matrix of 14x13 individual sensors, created by sandwiching velostat between orthogonal copper tapes. These copper strips are connected to a microcontroller via multiplexers, enabling the measurement of pressure distribution across the feet. The pressure variation, corresponding to changes in resistance, is monitored and controlled through an Arduino microcontroller. The data is projected onto a system display, allowing for the classification of foot postures into categories such as normal stance, tiptoeing, heel standing, over-pronation, and under-pronation.
