Wearable medical device has been a resurgence of interest thanks to the development of technology andpropagation of smart phone in recent years. Various types of wearable devices have been introduced and availablein market. Capacitive coupled electrode which measures electrocardiogram over cloth is able to be applied wearabledevice. In previous approaches of capacitive electrode, they need proper pressure for stable contact of the electrodeto body surface. However, wearable device that gives pressure on body surface is not suitable for long-term monitoring. In this study, we proposed adhesive polyurethane-based capacitive electrode for patch-type wearable electrocardiogram(ECG) monitoring device. Self-adhesive polyurethane make the electrode and whole system beadhered to the surface of skin without any pressure. The patch-type system is consisted of analog filter, analog-todigitalconverter and wireless transmission module and designed to be attached on the body as a patch. To validatethe feasibility of the developed system, we measured ECG signal in stable and active state and extracted heart rate. Therefore, we observed skin response after long-term attachment for biocompatibility of the adhesive polyurethaneand adhesive strength of it. The result shows the possibility of applying the developed system for ECG monitoringin real-life.
