The characterization of human gait using force platforms is one of the finest areas of biomechanics. Typically these force platforms are large, fixed and restricted to a laboratory environment. Therefore, a system for monitoring the human gait that is flexible, small-sized and can be installed in the actual sole of a shoe is desirable for many applications. We developed a portable, low- power consumption system to continuously monitor the forces involved. Exper- imental data were compared with simulated data using finite elements method (FEM). The results showed that the system was stable and adequate to applica- tion proposed. Results showed a linearity error of 1.25% on the vertical axis, revealing the smooth functioning of the system. Found deformations in the load cells were compared with the simulated model, showing a difference of 5.8% at most. This system might be helpful to monitor force measurement for the hu- man gait.
