Problems solved by technology

Due to the large size of the traditional EEG amplification system, high cost and inconvenient portability, patients can only go to specialized hospitals or research institutions for related tests
Portable EEG machines that have become popular in recent years are also connected by USB cables, and their mobility is also limited, resulting in low popularity among individuals and families.
Therefore, the portability and accuracy of the EEG signal acquisition system has always been a very attractive but quite difficult research topic.

Abstract

The invention discloses an electroencephalogram signal wireless collecting system which comprises a control module, a wireless electrode cap module and an electroencephalogram processing module.The control module, the wireless electrode cap module and the electroencephalogram processing module are each provided with a wireless signal transmission module.The wireless electrode cap module further comprises a microcurrent stimulator, a dry electrode and an electroencephalogram resistance detecting device.The microcurrent stimulator receives a control instruction wirelessly sent by the control module and simulates the electrode to output simulation current to act on scalp.The dry electrode collects an electroencephalogram signal fed back by the scalp and sends the signal to the electroencephalogram resistance detecting device, and the signal is processed and then transmitted to an amplifier through the corresponding wireless signal transmission module to be amplified.The dry electrode structure in the electroencephalogram signal wireless collecting system is improved, the dry electrode can make tighter contact with scalp, and the signal to noise ratio is higher.

Description

technical field [0001] The invention relates to the field of electroencephalogram signal acquisition. More specifically, the present invention relates to a wireless collection system for EEG signals. Background technique [0002] EEG signals are not only an important reference for the diagnosis and treatment of epilepsy, attention deficit hyperactivity disorder and other mental diseases, but also the most important source of information for the rapid development of cognitive science research in recent years. In engineering, EEG signals also have corresponding applications. For example, Japan's Honda Motor Company has developed a robot controlled by human brain ideas. Professor José Del Milan of the Swiss Federal Institute of Technology in Lausanne uses EEG signals to implement a brain-computer interface (BCI), enabling disabled people to control wheelchairs with their minds. Due to the large size of the traditional EEG amplification system, high cost and inconvenient port...
