- Abstract
- Recently, microplastics have become a big problem, but conventional particle analyzers that can detect microplastics require a lot of time and cost, so in this paper, in order to solve this issue, a low-cost RF sensor was designed to detect microplastics through it. The RF sensor was designed using the L-C-L resonance structure, and the microplastic concentration was detected through the change of the dielectric constant by collecting microplastic in the dielectric space between the capacitors. Through the RF sensor designed in this study, it was confirmed that microplastics as small as 0.1% can be detected, and it was confirmed that a single particle can be distinguished through a readout circuit.
