設計與實驗驗證之 16 通道主動式腦波量測系統 使用彈簧式乾電極

The brain-computer interface (BCI) technique is one of a major method that provides a direct communication pathway between the brain and the external world by translating signals from brain activities into machine codes or commands. In recent years, the EEG-based BCI system was widely applied in daily life. In this thesis, we try to design a wireless transmission, portable, active circuit EEG signal acquisition system with dry sensors. The advantage of active circuit was used to improve the performance of using dry sensor. Normal people can also enjoy the convenience from BCIs in daily life by using this system. To verifying this system, we design five experiments, including two general EEG-based BCI experiments. In these experiments, two reference systems were used to comparing with this system, so that we can observe the performance of this system.
