| Abstract(in English) | A test equipment that can evaluate the contact resistance and amount of noise of EEG sensors is proposed in this study. An EEG is easily masked by the noise derived from contact resistance, because of their feebleness. To realize a low-noise measurement, the contact resistance and the amount of noise of EEG sensors need to be investigated prior to measuring the EEG. A pseudo-skin made of conductive rubber was employed in this study to evaluate the performance of the sensors, similar to actual working conditions. The proposed device is composed of the pseudo-skin, signal-generating circuits to imitate EEG signals and pseudo hum noise on a minute scale, and a coil to emit the pseudo hum noise into the test space. The contact resistance of the pseudo-skin can be compared to that of human foreheads. The experimental results indicated that the standard deviation of the contact resistance of the pseudo-skin is smaller than that of the human foreheads. This result demonstrated that the pseudo-skin is suitable for contact resistance evaluation of the EEG sensors. In addition, the correlation between contact resistance and the amount of noise was evaluated to assess the validity of the system. An increase in the amount of noise with the increasing contact resistance was observed from the results. Further improvement of the device and an intensive study of the evaluation method of noise are required in future, in order to establish an efficient evaluation method for EEG sensors. |
