Restoring Human Grasp Functionality Through Soft Hand Exoskeletons

This work analyzes existing soft hand exoskeleton models in-depth, points out their drawbacks and difficulties, and offers design suggestions that prioritize adaptability, comfort, and compactness. The key areas of interest are the tendon-driven mechanism, tendon routing, and dynamics analysis because they provide essential knowledge for selecting the optimum design, material, and functional features to improve the exoskeleton’s usefulness and usability for persons with hand impairments. To choose the best materials for 3D printing and ensure structural integrity, the task starts by determining the maximum forces and tendon tensions that the exoskeleton must withstand. When evaluating the flexibility and efficiency of the design, tendon routing is a crucial factor. The functioning and responsiveness of the tendon-driven fingers are further evaluated using a thorough dynamics study. This paper offers valuable information on design considerations, material choices, and functional elements of the soft hand exoskeleton by focusing on these crucial areas. The results of these studies and the novel insights they offer open the door to the creation of more useful and effective designs that will enhance usability and functionality for people with hand restrictions.
