A personalized flexible exoskeleton for finger rehabilitation: a conceptual design
Several robotic rehabilitation systems have already been developed for the hand requiring the biological joints to be aligned with those of the exoskeleton making the standardization of this devices for different anthropomorphic sizes almost impossible. This problem together with the usage of rigid components can affect the natural movement of the hand and injure the user. Moreover, these systems are also typically expensive and are designed for in-clinic use as they are generally not portable.
Biomimetic and bioinspired inspiration using soft robotics can solve these issues. This paper aims to introduce the conceptual design of a personalized flexible exoskeleton for finger rehabilitation modelled around one specific user’s finger with the help of a 3D scanning procedure presenting a dynamic FEM analysis and a preliminary prototype obtaining a low-cost and easy to use and wear device.
