© 2016 IEEE.In this paper, we propose a novel photonic crystal sensor based on refractive index sensing method. The proposed photonic crystal sensor design has a T-shaped sensing slot region to inject bio-material samples with different refractive index values between 1.00 and 1.35. The corresponding highest refractive index unit (RIU) sensitivity of the designed photonic crystal is numerically calculated as 1016 nm/RIU. The designed photonic crystal sensor can be especially utilized for analysing different gas contaminations and diabetic blood samples in the healthcare sector.
