 This paper examined the effects of different tendon topologies and material properties on the grasping quality of a human hand model. The results showed that the lateral band and extensor hood were critical components for maintaining grasping quality. Additionally, the dexterity and grasping quality of robotic and prosthetic hands could be improved by integrating these two components. Furthermore, the study demonstrated that there is no need to use very stiff tendon material as it will not help to effectively enhance the grasping quality.
