This study aims to develop a simple device for plantar pressure measurement, which is low cost and easy to use. The developed device is an insole system, which had been designed and developed to measure plantar pressure during dynamic movement in real-time. For each insole, three force sensors were placed on the locations of heel, the 1st and 5th MTH, which are the important zones of foot biomechanics. The force sensors used in our experiments were piezoresistive sensors. The control boxes at waist received the output from force sensors in each insole and then converted analog signals to digital data. The digital data were linked to a personal computer using wireless Bluetooth communication. A LabView program was also developed plot and analyze the gait data. Thirty subjects which were 10 men and 20 women, were measured twice by the developed device and the F-scan, which was a tool reference. The t-test for independent samples showed that the average of peak plantar pressure values from the developed device and F-scan which is the tool reference had significantly different (α = 0.05). The intra-class correlations showed that the developed device had correlated to the tool reference. The plantar pressure measurement confirmed that the developed system is able to measure the static and dynamic plantar pressure in real-time.
