N2 - In this paper, we present a low-cost, robust and high-sensitivity microwave-microfluidic sensor system based on a 11 × 11 arrays of symmetric composite SRR (SCSRR). The proposed microwave passive device, which operates at around 11 GHz-22GHz and is excited by a pair of patch antennas, is designed to identify different liquid samples with high permittivity, such as water-ethanol mixtures of different concentrations. Microfluidic channel is integrated into the substrate interior which improves device integration greatly. The simulated results show that the resonant frequency shiftf of these two resonance peaks at 13.29 GHz and 20.85 GHz is around 2.5 GHz and 6.5 GHz as the liquid samples permittivity changes from 9 to 80. The proposed metamaterial-inspired sensor has higher sensitivity and larger frequency shift f on liquid samples compared with the conventional sensor reported in other literatures. As a passive device, this metamaterial-microfluidic sensor offers a potential lab-on-chip solution for liquids with high permittivity.
