Abstract

A microstrip line split ring resonator (SRR) sensor is introduced for liquid profiling. The sensor features a microstrip transmission line with two identical SRRs, detecting differential permittivity by loading liquid samples onto the SRRs.3D-printing stereolithography technology with high temperature resin is used to build the sensors. The printed sensor undergoes metallization process by depositing titanium and copper layer, followed by copper electroplating. Different Ti Cu sputtering time was studied to determine optimum parameters for sensor application. It only necessitates a minimal sample volume for detection as any changes in the sample loading induces a change in the resonance frequency of the SRR. The sensors exhibited strong performance, distinguishing between chemicals like methanol, IPA, and silicone oil based on resonance frequency shifts, with the 3.5 GHz sensor achieving the highest sensitivity (1.09 %). The utilization of additive manufacturing for producing 3D-printed sensors could meet the demand for quick and cost-effective microwave sensors.

期刊介绍： Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications. Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques. Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals. Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review. The Journal is owned by the Korean Physical Society.
