Multi-modal Bio-signal Sensor System (MBSS): Simultaneous Monitoring of Electrocardiogram, Respiratory Waveform, and Electrogastrogram

Abstract

We developed abdominal-attachable wearable multi-modal bio-signal sensor system (MBSS) for simultaneous monitoring of three different bio-signals: electrocardiogram, respiratory waveform, and electrogastrogram. We collected the three bio-signals from seven subjects with using both MBSS and commercial bio-signal amplifiers, then verified the practical reliability of MBSS. For all of the three bio-signals, we found that the coefficients of determination was high enough in feature analysis. We expect that MBSS can be utilized in multiple bio-signal studies, expecially for the purpose of clinical application.
