Simple Insole for Dynamic Foot Plantar Measurement in Walking Gait Analysis Using Force Sensitive Resistor

There are 2 types of footprint scanning, namely scanning is not burdened and burdened. The pressure distribution on the soles of the feet depends on many factors such as body mass index (BMI, kg / m2), sex, foot contact area or foot type and daily activities. Measuring the pressure distribution in the soles of the feet is done to help in orthotic shoes for sufferers on the soles of the feet and certain sports shoes. For this purpose, we must know the parts of the foot that receive a large load when walking, running well. The human foot is divided into 3 parts, namely the top, middle and back. The purpose of this study is to improve and conduct testing to study the distribution of the soles of the feet both while walking and then carrying out the validation of the results of the assessment with several studies that have been done by previous researchers. In this study to study the pressure distribution on the feet, the insole has been placed 24 sensors (12 sensors on each foot). Sensor data will approve with microcontroller, and the final results are shown using special software. Tests data were obtained from 10 subjects with foot size 40 and body mass varying. Tests are performed when 1 running cycle consists of 4 phases, namely heel strike, loading response, terminal position, and preswing.
