A low cost smart healthcare monitoring system using Li-Fi technology

In the Intensive care unit (ICU) environments, patients require a continuous healthcare monitoring system to monitor their vital signs. This system must be cheap, smart, secure, easy to use, and not interfere with radio frequencies (RF) or sensitive electronic devices. In this paper, a novel design and implementation of a smart healthcare system are described using the newly emerging technologies of Li-Fi and IoT. The heartbeat rate and temperature of the patient are transmitted via Li-Fi technology and then to the central nurse station. This data is uploaded to the ThingSpeak platform cloud so that the doctor can view it anywhere. This system is also provided by sending email notifications in abnormal cases.
