Prometeus will developed a cloud-based app with a double interface, one for health care personnel (HCP) and one for the families with their newborn babies in the neonatal intensive care unit (NICU). The app will incorporate the “digital twin” neonate. The digital twin is the functional interface that will guide HCP in neonatal care by providing nutritional guidance and alerts from the Prometeus on- body monitoring tools. The family-interface, in contrast, will inform families on baby wellbeing and progresses with respect to the goals of the care, and allow them to have a protected, remote, and real-time interaction with the caregivers in NICU.
