Abstract
Prosthetic hand is usually made by rigid body mechanism with ropes and pulleys. Such a hand is not “soft” to patients or to objects to be manipulated by the hand. In this paper, the concept of compliant mechanism is applied to prosthetic finger. The main challenge in designing and constructing such a finger lies in the design of flexure hinge. First, a fully compliant finger with a monolithic structure and flexure hinge was built. Then, finite element analysis for the compliant finger was implemented, and the results were compared with the experimental result to verify the design. Finally, the complaint finger was applied in a prosthetic hand design and worked excellent with the hand.
