Abstract:
Devices for Ubiquitous-Healthcare have been currently developed to monitor health state unconsciously. Especially, measuring electrocardiogram (ECG) non-invasively on a bed has an advantage of long-term monitoring. We developed a simple and easy-to-use ECG measurement system on the bed with conductive textile sheets. It was arranged through experiments to monitor ECG more stable. Three male subjects participated in our experiment to measure ECG with four postures; a supine, prone, right lateral, and left lateral posture. Error rates of heart rate variability and correlation of RR-intervals were analyzed to evaluate the performance of the designed system. The results showed that the performance of the developed system was affected by environmental conditions, posture types and subjects.
