The NeuCyber Array BMI System, a self-developed brain-machine interface (BMI) system from China, revealed a remarkable feat: a monkey with its hands restrained and soft electrode filaments implanted in its brain, controlled an isolated robotic arm and grasped a strawberry by simply using its thoughts. The NeuCyber Array BMI System is composed of three major components: high-throughput flexible micro electrode array, a thousand-channel high-speed neural signal acquisition system, and a generative neural decoding algorithm based on a feed forward control mechanism.
The electrodes determine the quality of the recorded brain signals and the accuracy of brain control. It makes use of a large number of electrode contacts on a thin electrode thread to enhance signal capture ability. The electrode filaments made of flexible materials needed to be viewed under a microscope. The material fits well with brain tissue. The generative neural decoding algorithm based on the feed forward control mechanism of the system can establish an accurate mapping between neural activity in the cerebral cortex and motion parameters.
