Large-scale Magnetron Flexible Brain-computer Interface And Preparation Method Thereof

1. The present invention relates to the technical field of brain-computer interfaces, in particular to a large-scale magnetically controlled flexible brain-computer interface and a preparation method thereof.

Background technique:

2. The current clinical monitoring of EEG signals is mainly achieved by monitoring the electrical signals of the cerebral cortex through a brain-computer interface to draw an electroencephalogram (eeg). Due to the poor spatial resolution of cortical EEG and the development of medicine and neurology, the requirements for EEG signal acquisition have turned to deep brain EEG and the exploration of neural signal pathways and potential brain circuits across multiple brain regions, which makes it possible to Research on brain-computer interfaces implanted in the deep brain is imminent. Brain-computer interface is a method that uses electrophysiological detection as a means to establish a continuous and direct expandable path between the brain and external devices. On the one hand, it can obtain electrical signals that can be recognized and processed by external devices to achieve effective control; On the one hand, it can input feedback from external devices to the brain to form a closed loop and realize information exchange. However, the traditional brain-computer interface uses rigid implantable electrodes, which is more destructive to the tissue when multiple electrodes are implanted, and it is difficult to change the position after implantation, and the range of electrical signal acquisition of neurons is limited.
