Abstract

Abstract: Abstract: Prosthesis is an optional alternative for the people and individuals, who have lost their legs by birth or by infections or by injury. Manufacture and alterations of prosthetic socket is possible by the weight estimation between amputee's remaining limb and prosthetic attachment. This work is to fabricate the socket and above knee prosthesis using the foot made up of polyurethane foam rubber and to distinguish the pressure, weight, position and movement of the remaining appendage as for the prosthetic attachment, and to create sensors and actuators based prostheses. Measurements for both amputed leg and normal leg is taken, and the sensors are placed at three important parts of the stump, namely ischial sheet, middle of stump and end point of stump, the maximum pressure is determined, which plays an important role in the prosthetic socket fabrication, modification and optimal fit.
