Smart Sock Heart Rate Monitoring in Hospitalized Newborns

The goal of this observational study is to evaluate a commercially available smart sock for heart rate monitoring in hospitalized newborn infants without known heart disease. The study aims to determine whether the smart sock provides heart rate information comparable to that obtained from the standard patient monitor used in routine neonatal care. The main questions this study aims to answer are: * Does the smart sock provide heart rate measurements comparable to those obtained from the standard patient monitor? * Does the smart sock provide comparable information on clinically relevant rhythm abnormalities? * How do parents and healthcare professionals perceive the usability and safety of the smart sock? Participants will wear the smart sock while undergoing routine monitoring on the neonatal ward. Heart rate and rhythm data from the smart sock will be compared with data from the standard patient monitor. Parents and healthcare professionals will provide feedback on the usability and perceived safety of the device.

Inclusion Criteria: * Hospitalized newborn infant * Age \
