Capacitive Electrode Based Single Lead ECG Detection

Abstract

In recent years, advancements in medical and healthcare-based embedded systems have increased rapidly. Such systems include magnetic resonance imaging (MRI), computed tomography (CT) scanners, ultrasound imaging, digital flow sensors, electrocardiogram (ECG), an electroencephalogram (EEG) monitoring appliances. With the advancements in VLSI and e-technology, the overall chip size has reduced, and eventually, the functionality of the system has increased manifolds. In bio-medical applications, electrodes are widely incorporated to sense the electrical activity of the human body. One of the vital use of the electrodes is to sense the ECG signal of the patient’s body for monitoring the activity of the heart. For this purpose, several electrodes like dry or wet are used. In this paper, an effective capacitive electrode-based single-lead ECG system has been explored and its performance is accessed using Wilson central terminal ECG database. The proposed system has a very good correlation with the original ECG signal database. The presented capacitive-based electrode is proposed to be an optimal electrode for ECG signal detections in upcoming bio-medical applications.
