Description

technical field

[0001] The invention relates to the acquisition and processing technology of bioelectrical signals in the field of biomedical engineering, in particular to an integrated device for transcranial direct current stimulation and near-infrared detection. Background technique

[0002] Transcranial direct current stimulation (tDCS) technology and near-infrared brain functional optical imaging (Functional near infrared spectroscopy, fNIRS) technology are gradually becoming mature and applied in scientific research and clinical treatment. tDCS is mainly used for the regulation of brain function, and fNIRS is used for the state monitoring of brain function. Real-time monitoring of brain function regulation is of great value for clinical applications. At present, two independent devices must be used to stimulate and detect brain function regulation. Moreover, these two devices have their own front ends, and there is also the problem that it is difficult to overlap the...
