Microplastic detection sensor and microplastic detection system using the same

Abstract

Proposed is a microplastic detection sensor for detecting information about microplastic contained in a sample. The sensor may include a fluidic channel substrate including an inlet and an outlet, and a plurality of RF resonance structures. The inlet may be formed on one end of the fluidic channel substrate, and the outlet may be formed on the other end. The fluidic channel substrate may have a microfluidic channel formed therein to connect the inlet and the outlet. The microfluidic channel may move the sample toward the outlet by capillary action. In the fluidic channel substrate, a plurality of capture parts, respectively corresponding to the RF resonance structures, may be formed along the microfluidic channel and may selectively capture the microplastic by particle size. The RF resonance structures may output information about the microplastic captured in the corresponding capture part through RF resonance for the applied RF signal.
