Realization of accurate urine-glucose sensor using triangular photonic crystal structure

Urine-Glucose sensor using triangular photonic crystal structure is reported in this paper. In this work, photonic crystal is realized by considering glass (VITRON-IG) as back ground material with periodic six numbers of air holes containing different percentages of glucose in human urine. The principle of estimation of glucose in urine is based on variation of photonic band gap of aforementioned structure. The output beam emerging from above said crystal structure containing different percentages of human urine depends on both absorption and reflection loss. Simulation result reveals that output energy increases from 0.719 eV to 0.722 eV with glucose concentration, which varies from 0 gm/dL to 10 gm/dL. Finally, the output result along with glucose concentration is displayed using Arduino development board.
