Abstract

The aim of this paper is to develop nonintrusive type ECG monitoring system based on active electrode with conductive fabric. Our developed electrode can measure ECG signal without the electrolyte gel or the adhesives causing skin trouble. For the stable measurement of ECG signal, the buffer amplifier with high input impedance and the noise bypassing shield with conductive fabric were developed. This system involves real-time ECG signal monitoring, and wireless communication using the Zigbee protocol. We show experimental results for developing wearable ECG monitoring system and demonstrate how it can be applied to the design of nonintrusive electrode with conductive fabric.
