The combination of the metamaterials and microfluidic technology has provided a new research direction for higher sensitivity sensors. In this paper, an asymmetric metamaterial structure based on FANO resonance has been proposed. That structure is very sensitive to the small change of the dielectric constant. The simulation result shows that the resonant frequency moves 56 MHz averagely when the dielectric constant changes by 0.2. The measurement result is in good agreement with the simulation result in terms of the resonance frequency. That sensor has high sensitivity and great potential for chemical and biochemical detection in the future.
