I. Introduction
Remote monitoring of in-hospital patients or chronically ill patients at home is becoming an essential component of any modern healthcare system. It not only improves the healthcare delivery but also reduces cost of care. The need for this feature is further pronounced with the onslaught of deadly viruses, such as COVID-19, where personnel traffic in and out of hospital units needs to be minimized. Furthermore, sensor-based vital sign monitoring can also help increase accuracy of the data captured.
