Abstract

Electroencephalography (EEG) is a test that diagnoses epilepsy and measures brain function. During EEG, the space between the electrode and the skin is filled with a conductive paste to reduce the impedance between the electrode and the scalp, which helps measure the EEG signals. This study compared the artifacts of the two representative conductive pastes (Ten20 and Elefix). The artifacts, noise, and satisfaction were surveyed after using the two conductive pastes. The two conductive pastes had similar artifacts and noise, but the survey results showed that the Elefix conductive paste had better satisfaction and adhesion. This result may be explained by the imprinting effect according to the experience of using the Elefix conductive paste first in the EEG class. Hence, further research is needed.

뇌파검사는 뇌전증을 진단하고 뇌의 기능을 측정하는 검사로, 검사 시 전극과 피부 사이의 공간을 전도성 접착제로 채워 전극과 두피 사이의 저항 값을 줄여 보다 분명한 뇌파측정신호를 측정 및 접착을 돕는다. 이 연구의 목적은 현재 사용되는 대표적인 2가지의 전도성 접착제(Ten20, Elefix)의 인공산물, 교류혼입의 비교 및 두 가지 전도성 접착제 사용 후 만족도 조사를 실시하였다. 두 가지 전도성 접착제의 인공산물 및 교류혼입의 차이는 관찰되지 않았으나, 검사를 실시한 학생을 대상으로 한 설문 결과에서 Elefix 전도성 접착제가 더 좋은 만족도 및 접착력의 정도를 볼 수 있었다. 그러나 이는 현재 설문을 진행한 대상이 뇌파검사 실습수업에서 이미 Elefix 전도성 접착제를 먼저 사용해 본 경험에 따른 각인효과에 의한 결과일 수 있어 추가적인 연구가 필요하다.
