Restoring motor and SENSory functIons with a wearaBLE sensorized hand EXOskeleton (SENSIBLE-EXO)
In this project, we propose a real-time sensorized hand-exoskeleton that combines the tenoexo (RElab) and the sensory feedback based on TENS (NeuEngLab) systems. The integrated robotic system will be able to provide the user with assisted grasping force control via tenoexo and with fine grip-force f
Over 50 million people worldwide suffer from persistent neuromotor hand impairment. The RELab developed a robotic hand orthosis, the RELab tenoexo, to provide grasp assistance in therapy and activities of daily life. User studies in people with a spinal cord injury (SCI) proved the potential of the robotic hand orthosis but also highlighted room for improvement in terms of functional assistance and provided grasp force. Transcutanoues Electrical Nerve Stimulation (TENS), as developed at the Neuroengineering Lab, has the potential to improve grasp function by providing sensory feedback or targeted muscle activation. This project aims to develop and evaluate a proof of concept of the combination of specific patterns of electrical stimulation with the RELab tenoexo.

In the first part of the project, the student will familiarize with the RELab tenoexo, gain experience from running user studies, and prepares the required hardware (electronics, actuation system). Based
on these insights, the targeted use case will be refined. Afterward, the student will familiarize with the electrical stimulation principles and he/she will adapt the system developed at the Neuroengineering Lab for the specific application. The robotic hand orthosis and electrical stimulation will be integrated to create a closed-loop hand assistive device that improves hand function in people with SCI through the combination of mechanical assistance, augmented sensory feedback, and potentially functional stimulation.Finally, the student will design tasks to evaluate the functionality and benefit of the combined approach in neurologically intact subjects and people with SCI.
