Description

technical field [0001] The present invention relates to the research field of a vital sign parameter detection device, and specifically refers to an EEG detection device based on a wearable device. Background technique [0002] Electroencephalogram EEG (Electroencephalogram) is the potential synthesis generated by the physiological activities of neuron cells in the brain. Interface and other research on brain science. In the study of EEG, the acquisition of EEG signals is particularly important. The acquisition of EEG signals is completed through the EEG acquisition system. However, traditional EEG acquisition systems generally consist of Composed of multiple channels formed by multiple electrodes, it is bulky, high power consumption, and inconvenient to operate. The limitation of multiple electrodes makes it difficult to collect EEG independently, and usually requires the assistance of others to complete the placement of EEG electrodes. [0003] With the improvement of peo...

Problems solved by technology

[0004] Although a series of wearable EEG monitoring devices have appeared on the market, most of them adopt an EEG acquisition system composed of multiple channels formed by multiple electrodes, and are connected to the EEG for display through the equipment adapter cable. , the limitation of this connection makes it difficult to place EEG electrodes independently, and at the same time, it will greatly limit the real-time monitoring and stability of EEG, thus affecting the accuracy and real-time performance of monitoring results

In addition, the power supply of existing EEG detection devices is almost all powered by batteries or recharged by power sources. This power supply method greatly limits the usable time of the detection devices and cannot meet the needs of monitoring anytime and anywhere.
