Abstract: This study is devoted to the design of process for a low-cost mechatronic device intended for measuring the lower limb amputee stresses. This development is based on a biomechanical analysis and the force data obtained in a gait laboratory whereof a force and stress analysis over the stump-socket interface could be done. Later, gait critical conditions are simulated for acquiring the theoretical results needed to do a sensors selection (Flexiforce-Teckscan®). Once the selection is done, a sensors mesh is presented as a measuring device as well as the electronics for signal conditioning and the software for results analysis and presentation. This device is calibrated and validated by means. Finally, the device assembly is done with commercial prosthetic elements in order to proceed with the critical conditions tests and to get the experimental data. The data is compared with the theoretical results as the designed device validating stage.
