Abstract

Recently, as we move toward a society with an increasingly aged population, wearable U-health devices in various shapes with smart wear have been developed in order to conveniently measure health variables without using hands in daily life or at home. However, the problem is that only supply of the wearable U-health devices is focused and its applicable devices are studied and developed, which has resulted in lack of awareness of importance of performance evaluation. In this study, two electrodes were fabricated using conductive fabric which can be used as electrode if attached to wearable U-health devices or smart wear in order to measure ECG signal. Two electrodes those were fabricated using conductive fabric were compared the correlation, impedance and CMRR with patch typed Ag-AgCl electrode-normally used for measurement of ECG signal, so that the study would find out if the fabricated electrode can be used with the wearable U-health devices by testing and evaluating performances.

인구의 고령화 사회에 접어든 최근에는 스마트 의류와 접목된 다양한 형태의 착용형 유헬스 디바이스가 개발되어 일상생활과 가정에서의 생활에 양손을 자유로이 하여 불편함 없이 건강변수 측정이 가능하게 되었다. 하지만 착용형 유헬스 디바이스의 보급과 더불어 이를 응용한 디바이스에 대한 연구 및 개발만이 우선되고 있는 현재, 이에 대한 성능 평가의 중요성에 대한 인식은 미흡한 실정이다. 본 논문에서는 이러한 착용형 유헬스 디바이스와 스마트 의류에 접목하여 전극으로 사용될 수 있는 전도성 섬유를 이용한 전극을 구성하여 심전도(ECG) 신호 측정을 위해 일반적으로 사용되는 패치타입의 Ag-AgCl 전극과 임피던스(Impedance), 심전도(ECG) 신호의 상관관계 비교와 CMRR 측정을 통하여 착용형 유헬스 디바이스에의 사용 가능성을 밝히기 위해 시험을 통한 성능차이를 평가 하였다.
