It is necessary for many electrodes to paste on head in most of EEG measurement machine to extract EEG signals in the field of EEG analysis. This restricted its application in the portable EEG-signal acquisition. The main purpose of this paper is to implement a wireless sensor network to easily measure brain waves. We use a single electrode and a wireless Bluetooth interface to capture EEG signals. This study, we used the Schwab classification to classify the signals into β, α, θ, and σ waves. We processed the features of β and α waves to control several devices. In the simulation results, the proposed system not only reduces the physical size but also extract EEG signals with a portable manner.
