A Wearable Plantar Pressure Measurement System: Design Specifications and First Experiments with an Amputee

In this paper, we present a wearable plantar pressure measurement system for locomotion mode recognition. The proposed system is implemented with four force sensors in each shoe to measure different given position pressure. By phase-dependent pattern recognition, we get reliable classification results of the six investigated modes for a below-knee amputee subject. The satisfactory recognition performances show the prospect of the integration of the proposed system with powered prostheses used for lower-limb amputees.
