The design of an Split Ring Resonator (SRR) based sensor is proposed for pisco concentration measurements through the characterization of the permittivity in liquids solutions containing pisco. The design is composed of two SRRs coupled to a loop structure. The principle of detection is based on the submersion of the sensor in pisco solutions with different concentrations. It generates a shift of resonance frequencies which is shown in the return loss response. This change is related to the permittivity of the measured solution. The SRR based sensor is a low cost, high sensitivity and reusable design.
