Abstract
Plate foot pressure is the pressure that exists between the foot and the surface under it. Information extracted from such pressure is used for research on gait, balance, shoe design, sport biomechanics and injury prevention. Therefore, it is necessary to develop methods and systems for measuring pressure. The purpose of this study was to design and validate intelligent insoles capable of measuring biomechanical gait variables. After careful examination of the results and diagrams, the Hall effect sensor was selected for implantation. After fabrication of the aforementioned insole, 10 subjects were randomly selected. Each participants had to perform both static and dynamic (walking) experiments. Tests were performed for the insole equipped with a Hall effect sensor and compared with the results of the tests with the Pedar insoles system. The results of the two Pedar and Hall effect sensor tests were matched and the numerical regression coefficient were close to one.
