Li-Fi Based Patient Monitoring System

Vivek Sangani

Abstract: Patient monitoring system using Li-Fi technology. Li-Fi stands for Light Fidelity. Li-Fi technology was invented and developed by the German Physicist Harold Haas provides transmission of knowledge through illumination by sending data through varies intensity faster than human eye can follow. Li-Fi may be a bidirectional, high speed and fully networked wireless optical communication and may be a sort of light communication. The proposed model helps within the patient monitoring within the hospitals and may be done by using the concept of Li-fi rather than Wi-Fi technology to avoid the frequency interference with the human body. Sensors such as temperature, heartbeat, motion, ECG cardiogram graph are used in the prototype to perform its respective functions. These sensors collect the data from the human body and then the data is sent to the ATmega8 microcontroller and then it converts digital signal into optical signal which is emitted by led or lasers and at the receiving end we have photo detectors to receive the light emitted signals and then it sent to another micro controller and then its connected to pc or display where it shows the readings of all the sensors attached to the patient?s body.

Keywords: Li-Fi technology, patient monitoring system, visible light communication, wireless, high speed, low latency, ecg cardiogram graph, heart rate, blood oxygen
