PROJECT TITLE :
The Lightweight Delft Cylinder Hand: First Multi-Articulating Hand That Meets the Basic User Requirements
Rejection rates of upper limb prostheses are high (23%–forty fivep.c). Amputees indicate that the very best style priority should be reduction of the mass of the prosthetic device. Despite all efforts, the mass of the new prosthetic hands is thirty fivep.c–seventy threepercent beyond that of older hands. Furthermore, current hands are thicker than a personality's hand, they operate slower and don't provide proprioceptive force and position feedback. This study presents the Delft Cylinder Hand, a body powered prosthetic hand that mass is 55p.c–68p.c under that of the lightest current prosthetic hands, operates faster, has an anthropomorphic form, and provides proprioceptive force and position feedback. The hand has articulating fingers, actuated by miniature hydraulic cylinders. The articulating fingers adapt to the form of the grasped object. Its purposeful scores are like that of current prosthetic devices. The hand incorporates a higher mechanical performance than current body-powered hands. It needs forty nine%–162% less energy from the user and it will deliver a higher most pinch force (30–60 N).
