• The aim of this work was to build and design a low-cost active hand exoskeleton to be used in rehabilitation of post-stroke patients. The hand exoskeleton was 3D printer and it allowed an active flexion and extension of the ngers. The exoskeleton designed was powered by three servomotors which pulled tendons to shorten the distance over or under the joints. This produced a natural hand movement close to a biological one. The exoskeleton was controlled by a Brain-Machine interface (BMI) utilizing an EEG-cap for measuring the brain activity. This way, two subjects tested the whole system opening and closing the hand exoskeleton by using only their thoughts.
