WebJan 1, 2010 · The hand prosthesis, called SmartHand, was controlled in real-time by using 16 myoelectric signals from the residual limb of a 25-year old male transradial amputee in a two day long evaluation ... WebOct 11, 2024 · The loss of hand functions in upper limb amputees severely restricts their mobility in daily life. Wearing a humanoid prosthetic hand would be an effective way of restoring lost hand functions. In a prosthetic hand design, replicating the natural and dexterous grasping functions with a few actuators remains a big challenge.

WebJul 28, 2024 · This nine-bar mechanism is integrated through a coupled four-bar mechanism and an adaptive seven-bar mechanism. The developed finger based on the nine-bar mechanism is able to improve the grasp stability in the global workspace under an extremely small spring stiffness. A quantitative analysis of the grasp stability was carried out. Due to its unique embedded features and human-size, the SmartHand holds the promise to be experimentally fitted on transradial amputees and employed as a bi-directional instrument for investigating -during realistic experiments- different interfaces, control and feedback strategies in neuro-engineering … See more The fingers have an architecture based on Hirose's design [36] and are composed of 3 aluminium phalanxes (proximal, intermediate and … See more In a majority of research projects on prosthetic hands, and in general in robotic hands, non-back-drivability is achieved by means of screw/lead screw pairs (as in all previously mentioned … See more The thumb has two DoAs: one for flexion/extension, plus one for abduction adduction. With reference to the natural hand, the equivalent trapezio-metacarpal joint (TM in Figure 1A) has 2 DoFs.
