Technical Field

Background
The high-precision transcranial electric stimulation (HighDefinitionTranscranialElectricalStimulation, HD-TES) TES is used as a current effective noninvasive physical intervention technology, is widely applied in the aspects of psychology, neuroscience, clinical medicine and the like, is more accurate in stimulation than the traditional tES technology, has more electrode sites, is a 4 multiplied by 1 annular electrode generally, and forms a loop with surrounding electrodes; functional near infrared (fnigs) is a novel brain imaging technology, which is more portable and has higher space-time diversity ecology than electroencephalogram and nuclear magnetism, and the technology emits laser or LED light through an emitting optode, light reaches the cerebral cortex after passing through tissues such as scalp and skull, returns to the scalp through the scattering effect of the light, is received by a receiving optode, and calculates the change of the hemoglobin concentration of the cortex through the change of light attenuation, thereby reflecting the neuron activity. HD-tES combined with fnigs is a brand new research model, combines the advantages of the two techniques, not only can observe neuroimaging changes while electrically stimulating, but also can ensure continuity of experiments, so that experimental results are more perfect. Because the action positions of the two technologies are at the head, but at present, no adaptive cap for synchronously operating the HD-tES and the fNIRS exists in China, so that the research of the two technologies is difficult to be smoothly carried out by scientific researchers. In particular, most domestic scientific research institutions adopt foreign electric stimulation and near infrared instruments, and the two devices cannot be effectively and simultaneously operated due to instrument brand difference, so that if caps are customized from abroad, the cost is high, and the middle communication time cost is also difficult to bear by most research institutions and researchers. The HD-tES has a plurality of electrode sites, and the fnires has a plurality of optodes sites (about 24 or more), and it is very difficult to fuse them on one experimental cap and cover the same brain area, so that it is urgent to make an experimental cap that is suitable for the combined use of HD-tES and fnires.
