Swiss engineers from the Federal Polytechnic School of Lausanne created a working prototype of an exoskeleton hand brush, which can control the power of thought. The developers were able to do without implanting the electrodes under the skin, placing them on a special rubber helmet.
Brain pulses are transmitted from the helmet to the metal "tendons", which are fixed to the wrists and fingers of the wearer with the help of Velcro fasteners, causing the patient's hand to move.
The exoskeleton itself is easy to handle, installed in a few minutes, and still has the function of controlling the movement of the eyes, which was provided for completely immobilized people. It has already been tested for survivors of stroke and spinal injury patients, now the developers want to improve its work in such a way that it helps people fulfill their daily tasks.
In the course of studies conducted by developers in the process of testing the exoskeleton, it was found out that when the thought is controlled by the apparatus of one hand, the brain regions responsible for the movement of the second arm are activated in the patient. Scientists plan to use this feature to improve development management and to complicate its design.
