摘要：
A new type of terahertz sensor with microfluidic and metamaterial fusion is designed in this paper. Taking ethanol aqueous solution as the research object, the terahertz spectra of ethanol aqueous solution with different mole fraction were analyzed and studied. With the increase of mole fraction, the terahertz resonance absorption frequency of ethanol solution decreases gradually, while the resonance summit appears blue shift to varying degrees. The quantitative detection of the mole fraction can be realized through the corresponding relationship between the blue shift of the resonance absorption peak and the mole fraction. The research results of this paper are helpful to promote the application of terahertz time domain spectroscopy in rapid, micro and real-time material identification and biosensor.
