Popovic, Marko B.
When an amputee wears a prosthesis for an extended period of time, the various pressures within the prosthetic socket due to cyclic loading often results in physical discomfort, swelling, and other potential issues within the residual limb. The goal of this project was to design and test a novel prosthetic socket for transtibial (below-knee) amputees that reduces stress on the skin and soft tissues of the limb by automatically redistributing the pressures between the limb and the socket. The final design consisted of a system of soft bladders and servo-actuated valves controlled using input from force sensors. All design specifications were met and pressures were successfully redistributed across the limb.
