The Neural Control of Movement (NCM) Lab in collaboration with the Rehabilitation Engineering Lab (RELab) is developing a wearable wrist exoskeleton with sEMG-based force control. While the measurement and analysis of residual sEMG signals in the patient's forearm provide information on the movement intention, a torque measurement at the wrist allows to apply the adequate mechanical support in order to enhance the rehabilitation process. Conceptually one might think about the operation principle of an electric bike which starts contributing to the effort only when the rider presses on the pedal. As a proof of concept, we developed the eWrist, a wearable one degree-of-freedom powered exoskeleton for the wrist.
This project will be to improve the actual design, especially the fixation system on the upper arm (cf. pictures).

This project will be to improve the actual design, especially the fixation system on the upper arm (cf. pictures).
As depicted on the attached pictures, electronics and battery are placed on the upper arm to reduce weight on the distal part of the arm. The actual fixation system is composed of a hook with magnetic guidance combined with a fastening mechanism. However, we think this design could be further improved in its usability and handling.
**Tasks**
- improvement of the fixation system on the upper arm
- improvement of usability (fixation, comfort)
- test sessions with healthy users
**Your Profile**
- self-organized and independent
- disciplined
- reliable
better to have:
- experience in CAD
- experience in mechatronics
nice to have:
- experience in rehabilitation
