Abstract：Plantar pressure distribution is closely related to human health, and abnormal changes in plantar pressure distribution are
early symptoms of some foot diseases. To help patients prevent foot diseases and monitor the distribution of plantar pressure in real-
time, a dynamic plantar pressure distribution measurement system based on a tactile sensing array is developed. The system has a total
of 48 sensing units, and the measurement error is less than %, which can accurately collect the pressure of each area of the sole of the
foot. The system adopts a wearable design, the data acquisition system is fixed on the ankle, then connected to the host computer through
Bluetooth. In addition, the traditional pressure analysis method cannot analyze the pressure distribution change during exercise. To
address this issue, a dynamic plantar pressure distribution analysis method is proposed. The plantar pressure data of the human body are
classified by the support vector machine, and the classification accuracy rate is %. On this basis, the typical pressure distribution
