▎ 摘　　要

NOVELTY - The system has a graphene heating film set on the surface of the body person. A temperature control chip is provided with an EEG collecting device and a graphene heating film. Multiple electrodes of the EEG collecting device are arranged on the head of the tested person. The temperature control chip is used for controlling the graphene heating film to emit infrared radiation wave, when heating to the preset temperature. The measured person is located in the radiation range of the graphene heating film. The infrared radiation wave is used for enhancing the frequency of generating Theta wave by the measured person. The EEG collecting device is used for generating the EEG after the measured person is radiated. The EEG includes the Theta-wave information generated by the person. USE - System for detecting electroencephalogram (EEG) wave for monitoring emotion and sleep state of human body. ADVANTAGE - The graphene heating film has excellent mid-far infrared radiation characteristics, which increases the occurrence frequency of the brain of the measured person to generate the Theta wave, thus improving the detection efficiency and precision of the theta wave brain electric signal. The human is relaxed and easy to enter shallow sleep. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an EEG detection method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a brain wave detection system. (Drawing includes non-English language text)
