The magic of technology is not far away from the people

Recently, Tianjin University and Tianjin People's hospital released the two sides jointly developed artificial neural rehabilitation robot System "Shenzhou", this is the world's first suitable for all limb stroke rehabilitation "pure idea control" artificial neural robot system.

Compared with the brain-controlled mechanical exoskeleton that appeared in the World Cup, "God work a" can truly realize the synchronous coupling between the cerebral cortex and the muscle activity, so that the body is free to move, think and walk in unity.

The conference site, a patient with hemiplegia through the system can "command" their original unable to move the limb to complete the corresponding action. The head of the project, Professor prescribes of the Institute of Fine Arts at Tianjin University, said stroke patients were damaged by the central nervous system or peripheral nerves, the brain was unable to send the correct instructions, or the instructions could not be transmitted to the peripheral nerves.

This system should not only correct and quickly decode the brain signal, "reshape" the central nerve, but also the bionic construction of a complete "artificial neural pathway", the human body damaged the central nervous and peripheral nerves connected. It needs to extract the EEG data of the experienced person first, then simulates the central nerve pathway through the asynchronous "brain-machine Interface" technique of EEG, decodes the movement idea information of the experienced person, and then drives the multistage nerve muscle electric stimulation technique to simulate the peripheral nerve pathway, stimulates the paralyzed limb to produce the corresponding action.

The system includes noninvasive EEG sensor module, imaginative action feature detection module, motion intention recognition module, Instruction coding interface module, stimulation information conditioning module, stimulation current output Module 6 parts. The experience needs to put electrodes on the head of a brain detector and install electrodes on the muscles of diseased limbs. Among them, "brain-machine interface" can read the EEG information, no longer need to put the chip into the brain or spinal cord, you can more accurately read people's minds

According to prescribes, brain-controlled mechanical exoskeleton is the use of passive mechanical traction, not muscle active contraction activation. and "God work a" is the use of nerve muscle electrical stimulation, analog nerve impulse electric stimulation causes the muscle to produce the active contraction, the movement of the skeleton and the joint produces the independent movement, and the human body autonomous motion principle is consistent. This is of great significance to the patient, who can not only complete the corresponding action, but also speed up the rehabilitation process.
