Abstract

Abstract: During people's normal movement, the sole of foot is the only part of human body that contacts with the ground. The pressure information of sole directly reflects the physiological health and movement posture of human. A plantar pressure measurement system was designed with an insole type for measuring plantar pressure during normal movement. The insole embedded five PVDF piezoelectric film sensors, and then places the insole in the measured sports shoes. In order to obtain better pressure response effect, two small raised blocks were pasted under each piezoelectric film sensor to increase the sensitivity of the sensor. The plantar pressure data was sent to PC by wireless serial port. An intuitive and easy-to-use GUI interface was designed by the MATLAB software. The interface can display the pressure distribution at each point of the sole of both feet.
