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.

Abstract: A thin film type resonator used in a wireless power transmission system is proposed together with a design method thereof. The thin film type resonator may include a thin film line formed in a spiral shape. The thin film line may have a form factor in which a width and a pitch of the thin film line gradually increase from an innermost portion to an outermost portion.

Abstract: Proposed are a microplastic concentration measurement sensor and a microplastic concentration measurement system using the sensor. The sensor may include a fluidic channel layer having a microfluidic channel formed on an upper surface thereof, and a molding layer formed on the fluidic channel layer and having first through-holes located respectively above one end and other end of the microfluidic channel. The sensor may also include a first substrate layer formed on the molding layer and having second through-holes located respectively above the first through-holes. The sensor may further include a single line formed on an upper surface of the first substrate layer, a second substrate layer formed below the fluidic channel layer, and a resonant layer formed on a lower surface of the second substrate layer.
