(a) Red: flexible structure before deformation due to the applied grip force . Blue: deformed structure when is applied. (b) Detailed view of an individual flexible hinge with the forces acting upon it and the resulting deflections. (c) Hinge parameters: length , width , and thickness of the flexible hinge. (d) Finite element model (FEM) analysis of the internal stress in a hinge when applying  N for a hinge thickness of  mm.
