Description
Summary:The human wrist contributes greatly to hand mobility and manipulation capabilities in healthy individuals, but both the commercial and research domains have often overlooked prosthetic wrists in favor of terminal device development. In this paper, we review the current state of the art of in a wide variety of passive, body powered and active wrists from both the prosthetics industry and research community. We primarily focus on the mechanical design and kinematic arrangement of these systems, giving details of articulation methods and specifications where possible. Among other take-aways, the review shows that very few powered wrists are available commercially, all of which are single-DOF, that multi-DOF wrist designs are most often serial chain systems, and that there seems to be opportunities for the development of body-powered wrist devices or wrists with a parallel kinematic architecture. Additionally, of the three DOF of the human wrist, radial/ulnar deviation is least commonly implemented in hardware.
