| Research Abstract |
Magnetic resonance imaging (MRI) was used to measure the structure of fingertip pulp and pulp deformation when pressure was applied to the fingertip. Using the results obtained, we attached the pulp portion to the frame of an electric artificial arm and measured the contact area during object grasping. We confirmed an increase in the contact area caused by the attachment of pulp, which was anticipated to improve object grasping. A human fingertip finite element model equipped with fingertip pulp was then constructed, and deformation caused by object grasping was analyzed. MRI measurements and fingertip deformation in the finite element analysis were well matched. Application of these results to electric artificial arms could lead to improved quality of life (QOL) of disabled individuals missing an arm, which might increase their initiative to participate in social activities.
