    摘要： A multimodal brain function signal acquisition device and method are provided. The device comprises: a cap; an electroencephalogram (EEG) signal acquisition device which comprises a support member and a plurality of acquisition tentacles; the support member is a hollow cylinder, the acquisition tentacles are disposed along a circumference of a first port of the support member, and the first port is connected to the cap; a near-red signal acquisition device which comprises a light guide column, a near infrared light source and a photodiode; the light guide column is a transparent hollow cylinder disposed within an inner periphery of the support member, the near infrared light source and the photodiode are disposed at a second port of the light guide column, and the first port of the light guide column is fixed on the cap; a transimpedance amplifier connected to the photodiode; a first analog-to-digital converter connected to the EEG signal acquisition device; a second analog-to-digital converter connected to the photodiode; and a micro-control unit connected to the first analog-to-digital converter and the second analog-to-digital converter.
