The bionic leg is the result of a seven-year research effort at the , directed by , the H. Fort Flowers Professor of Mechanical Engineering. The project was initially funded by a seed grant from the , followed by a development grant from the. Key aspects of the design have been patented by the university, which has granted exclusive rights to develop the prosthesis to , a leading developer and manufacturer of lower limb prosthetic devices.
A Confident Step Amputees must be able to rely on their prosthesis, especially in the stance phase. The rotation hydraulics of the 3R80 respond to the ground reaction forces in the stance phase at every step. They build up high hydraulic resistance, which prevents involuntary flexion of the joint.
