An application of terahertz metamaterials as transducer elements for chemical sensors is reported. A planar array of split-ring resonators was formed from gold on the surface of silicon wafer and coated by polyaniline. Analyte binding to polyaniline leads to well measurable changes of the resonance frequency.
