Project Overview

Modern passive ankle prosthetics do not effectively replace lost limbs. Problems arise with unnatural movement, creating joint stresses that cause rampant injuries in amputees. Fully-active prosthetics remove the unbalanced and harmful movement of the wearer. However, these solutions are limited due to their price, battery life, and weight. Therefore, there is a need to develop a semi-active prosthesis which can adapt to the movement of the wearer and allow for a more natural motion. This semester the group worked on modifying an existing semi-active model developed by our client to incorporate both toe and heel variable stiffness to better emulate natural movement.
