A Dry Electrode Based Headband Voice Brain-Computer Interface Device

摘要：

　　A new portable brain-computer interface (BCI) system for the inner ideas expressing by voice is designed and fabricated in this paper,The dry electrode is used in this system to record E1ectroencephaloFaphy (EEG),and it is fabricated using the standard micromachining techniques.Compared with previous designs,our system has features of light weight and convenient carrying.The system is mainly divided into three parts: signal acquisition,signal processing,and output control.The EEG signal is recorded by the dry electrode,and then amplified,processed successively by the application specific integrate circuit (ASIC),and the obtained processed signal can be used to control the external output equipment.A subjects attention amplitude can be nicely captured with our system,and the subjects could have the ability to express our real feeling through the EEG signal after training.
