In this paper, a new split-ring resonator variant, called the bended nested split-ring resonator (B-NSRR) is introduced. B-NSRR is a modified version of the nested split-ring resonator (NSRR) geometry, which has been successfully utilized in sensing of various physical quantities such as strain, displacement and moisture content due to its superior sensitivity, resolution and compactness in comparison to more traditional structures such as SRR and electrical SRR (ESRR). The B-NSRR geometry is demonstrated to allow an even more compact structure, while retaining the high sensitivity level of the NSRR. The performances obtained by the SRR, ESRR, NSRR and B-NSRR geometries are compared for displacement and moisture content sensing applications. Simulations are carried out to validate the findings, where modified versions of SRR-based structures are employed as displacement sensors and a comparison is made between their performances. Owing to its compactness and high sensitivity, it is shown that the B-NSRR is a reasonable alternative to available geometries in various sensing applications.
