A Conductive Fabric Based Smart Insole to Measure the Foot Pressure Distribution with High Resolution
This study presents a smart insole system made by pressure sensitive fabric. This fabric insole has 360 sensing arrays. Therefore, it can measure the foot plantar pressure distribution with a high resolution. An experiment was carried out to validate this system with the reference measurement system (F-scan). Ten participants were involved in an experimental study. The results showed that the fabric insole can measure the foot plantar pressure distribution accurately, with an average RMSE ranged from 22.46 kPa to 38.54 kPa for different balancing tasks.
