A method to accurately present intra-socket stress distributions on a 2D map of individual amputees’ residual limbs. The process was completed for a transfemoral amputee and verified through experimental pressure recordings, which were visualised on a specially developed desktop application.

Specially designed printed low-cost and lightweight shear and pressure sensors were successfully integrated in a transfemoral amputee’s prosthetic socket. Shear and pressure were measured simultaneously during dynamic and static activities. Repeated stress patterns were evident during walking.
