Different types of health monitoring systems are now available in the market. We are using them as a part of our day-to-day life to analyze health conditions. In the case of sea researchers and scuba divers, the medium they are working is water. The health difficulties are more inside the water. So there is a need to develop a health monitoring system for sea researcher’s/scuba divers to analyze their health condition frequently to ensure their safety. The proposed work uses LiFi technology as the communication method to transmit and receive corresponding bio parameter values. This work aims to provide a harmless wireless health monitoring system that will provide maximum efficiency inside the water.

This paper presents a low power capacitance to voltage converter (CVC) circuit using two differential amplifier circuits, two Schottky rectifier diodes constructed in symmetrical manner and combined with instrumentation amplifier circuits. The differential capacitance to voltage simulation work has been realized with cheap discrete components. Combination energy from solar, vibration and heat is expected to be used to source the capacitance circuit. Constant dc voltage of 3 V has been used to source the CVC circuit in this work. It is found by the simulation, the converter circuit consumes 3.9 mW of total power, operates at 40 kHz using 400 mV excitation signal. The circuit is able to detect changes of capacitance from 4 – 12.5 pF using reference capacitance of 5 pF. Sensitivity of 0.132 mV for 1 fF capacitance change has been observed in the circuit. This circuit is suitable for wireless health monitoring system.
