| Resumo: | This paper describes the development of a portable system for measuring and analyzing plantar load during the performance of the human gait cycle. The system comprises 24 resistive force sensors distributed along a flexible insole. The base of the insole was manufactured by 3D printing techniques using thermoplastic polyurethane, also known as TPU, as a flexible filament manufacturing material. Subsequently, Smooth-On brand EcoflexTM 00-30 polymer was poured into the base to generate a soft filler on the surface that will be in contact with the user. The electronic instrumentation of the system includes an Arduino® Nano coupled to a set of model CD4051BE analog multiplexers used to acquire the 24 signals. Wireless communication based on XBee® devices was used to transmit the collected data to a graphical user interface on a personal computer; designed to acquire, process, visualize and store the plantar loading measurements. Finally, the system’s performance was validated by testing with healthy volunteers to record the plantar load measurements obtained during a gait cycle |
