Prosthetic devices have significantly improved mobility and quality of life for amputees. Significant engineering advancements have been made in artificial limb biomechanics, joint control systems, and lightweight materials. Amputees report that the primary problem they face with their artificial limbs is a poorly fitting socket. In this project, we propose a smart prosthesis system, in which we measure the real-time force distributions within a prosthetic socket and dynamically visualize the results in a mobile application. A major part of the overall proposed system, a wireless pressure sensing system and a force visualization method, is evaluated at the current stage. Finally, corresponding works for fully completing this smart prosthesis system are discussed as well.
