| Popis: | AbstractAim This article introduces the giant magneto-impedance-based MEG detection technique to facilitate and inspire researchers wishing to engage in related studies.Methods We take non-invasive brain-computer interface (BCI) as the application background, and firstly analyze the advantages of magnetoencephalography (MEG) over electroencephalography (EEG) in terms of practicality, temporal and spatial resolution, and data acquisition. Then the development status of the major MEG detection techniques are overviewed. In addition, the circuit structure and research status of GMI sensor are outlined. Finally, the future development trends and challenges of the MEG-based BCI technology and the MEG detection technique based on GMI sensor are analyzed and summarized.Conclusion Detecting MEG signals in an unshielded environment is a worldwide challenge. The MEG detection technique based on the GMI effect has a promising application in the field of BCI, so it is significant to conduct the investigation of this technique. |
