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 thin film type piezoresistors. 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. The results of the initial tests related to walking rhythm that the dynamic plantar pressure graphs started changing from heel, and ended changing with the 1st MTH. Based on the initial study, the results had confirmed that the developed system is able to measure the dynamic plantar pressure in real-time.
