Description

technical field [0001] The invention relates to a plug-and-play electroencephalogram signal acquisition device applicable to research experiments of brain-computer interface technology, in particular to a brain-computer interface electrode cap based on an elastic array. Background technique [0002] Brain-Computer Interface technology (Brain-Computer Interface, BCI) is a new and effective information transmission and communication method that uses EEG signals to realize communication and control between the human brain and the outside world. It recognizes human intentions by detecting and discriminating the spatiotemporal patterns of different brain activities in EEG signals. The original intention of the research on brain-computer interface technology is to serve patients with motor neurological diseases. It does not require the participation of human body activities or language expressions, and it is non-action and non-contact. The basic principle is: when the human brain...

Problems solved by technology

[0006] Generally speaking, although the research in the field of brain-computer interface has achieved many theoretical and experimental results that are expected to reach a practical level, the current EEG signal acquisition equipment has design limitations, especially the front-end electrodes and electrode caps. The lack of mechanical engineering design has seriously affected the development of brain-computer interface technology to the practical stage. Therefore, the development of key equipment for brain-computer interface such as electrode caps is of great significance to the promotion and application of brain-computer interface.
