This work presents the development of a goniometer prototype to measure the knee joint angle. Three Hall effect sensors positioned at 120º to each other were used, together with a rectangular edge magnet positioned externally to these sensors. It was described the entire process of characterizing the sensors within the system, besides the structure of the goniometer. As a result, angles were measured from 0º to 140º, with a maximum measurement error of 1.015º. Finally, it was concluded that the prototype made it possible to measure the angles at the proposed values, in addition to bringing several proposals for system improvements for future work, such as the positioning of the sensors, improving the angle validation structure, among others. |
