Estimation of human-hemoglobin using honeycomb structure: An application of photonic crystal

This paper proposes a method to estimate the hemoglobin concentration in human blood using 2D honeycomb photonic crystal structure. Though a few works deal with similar kind of investigation, present research delivers an accurate estimation of hemoglobin as compared to previous works. The principle of investigation is based on linear variation of both photonic band gap and absorbance's with respect to different concentration of hemoglobin in human blood. Aside these variations, energy transmitted through honeycomb photonic crystal structure is also varied linearly with respect to same concentration. In this work, photonic band gap of honeycomb structure is found using plane wave expansion method, whereas absorbance of same structure is computed by employing Maxwell Curl equation. Finally, simulation result revealed that transmitted energy through two dimensional honeycomb photonic crystal structure containing blood is nicely fitted with linear trend line (R2 = 1) which lead to an accurate investigation of hemoglobin in human blood. At last, this paper proposes an experimental set up to measure the said concentrations with the help of an Arduino development board (Uno) containing Atmega 320 microcontroller.
