Flexure hinges inherently lose stiffness in supporting directions when deflected. This article presents a method for optimising the geometry of flexure hinges, aimed at maximising supporting stiffnesses. In addition, the new -Flexure Hinge design is presented. The considered hinges are subjected to a load and deflected a bidirectional angle of 20°. The optimisations show that the support stiffness is increased by a factor of 4.5 with respect to the conventional cross flexure hinge.
