A Project of a System for Measuring Child's Foot Pressure on a Shoe Sole

The project of the system to measure a child's foot pressure on the sole of a shoe is the theme of this article. The skeletal system and muscular system of human foot were discussed. The movement of the foot was also depicted. The definition of gait and gait phases were explained. In the next part of this thesis, the project of system to measure a child's foot pressure on the sole of a shoe was presented. The thesis includes: the specification of the force-sensitive resistors (FSR), their arrangement and connection method. The electronic circuit diagram of the measurement system was designed. All electronic components such as: microcontroller, analog switches, operational amplifiers, multiplexers and RS485 transceivers were discussed in detail. The project of printed circuit board was also created.
