Heart rate monitoring is the most important indicator to evaluate the clinical status of a newborn during birth. Approximately 90% of newborn infants make the transition from the intrauterine to extra uterine environment without major complications; however, the remaining 10% of newborn infants require assistance during this transition. Heart rate monitoring is required for guiding further interventions in the event of complications such as the requirement of resuscitation. In this work we evaluate the suitability of embedding electrometer-amplifier-based sensors employing novel screen-printing techniques into wearable medical devices. We compare our results with traditional copper based wired electrodes. Our implementation was able to acquire electrocardiogram with enough signal to noise ratio, suitable for heart rate detection having a 1% loss of heart rate accuracy, compared with the copper based electrodes. Our device has the potential to be embedded in wearable devices for assisting births though heart rate monitoring.
