Abstract

In this paper we implemented an EMG sensor system for wearable devices to obtain and analyze of EMG signals. The performance of the implemented sensor system is evaluated by the correlation analysis of muscle fatigue and muscle activation to clinical EMG system and compared with power consumption of the measured power of our system and commercial systems. In experiments with biceps and triceps brachii of 5 objects, The correlation values of muscle fatigue and muscle activation between our system and the clinical EMG system is 1.1~1.4 and about 1.0, respectively. And also the power consumption of our system is 25~50% less than that of some commercial EMG sensor systems.

본 논문에서는 근전도 신호 획득 및 분석을 위한 웨어러블 디바이스용 센서 시스템을 구현하였다. 구현된 시스템의 성능은 임상용 근전도 시스템에서 획득된 근전도 신호와 근피로도 및 근활성도의 상관성 분석에 의해 평가되었으며 실측된 소비 전력이 상용 근전도 시스템들과 비교되었다. 5명의 피실험자들의 이두박근 및 삼두박근에서 수집된 근전도 신호를 통한 실험에서, 구현된 시스템이 임상용 근전도 센서 시스템과 근피로도는 1.1~1.4의 상관성을, 근활성도는 약 1.0의 강한 양의 상관 경향성을 보여주었다. 또한 소비전력의 비교에서 구현된 시스템의 소비전력이 상용 근전도 시스템보다 25%~50%의 감소하였다.
