Contributor Van der Helm, F.C.T. (mentor) Faculty Mechanical, Maritime and Materials Engineering Department BioMechanical Engineering Programme BMD Date 2010-08-20 Abstract Body powered prostheses have many advantages: They are reliable, lightweight and relatively cheap. The disadvantage is the need of a shoulder harness, which causes discomfort, pain and trouble donning and doffing the prosthesis. The goal of this thesis is to develop a body-powered prosthesis without the need for a shoulder harness. This is realized by making a design that uses passive wrist flexion of the prosthesis itself to operate the grasping mechanism. The force and displacement are converted to a grasping motion by using a hydraulic system. The grasping force is enhanced by a pressure intensifier and holding an object is achieved by including an automatic lock.
