Semi-disposable Self-adhesive Sensor System for Wearable Electrocardiogram Detection

A wearable and semi-disposable electrocardiography (ECG) system is developed based on the self-adhesive ECG sensor patch, which can be fabricated by large area coating processes. The use of cobweb electrode and silicon adhesive film makes the sensor patch conformably contact the skin surface for low electrode-to-skin impedance and strong adhesion. The magnetic connection design enables easy integration to the ECG patch and reusability of circuit boards and batteries. The developed ECG sensor system was worn on a volunteer for real-time test. The results show that the measured signal quality will not be affected after normal activities.
