Applications of metamaterial sensors: a review

Abstract

Sensors based on metamaterial absorbers are very promising when it comes to high sensitivity and quality factor, cost, and ease of fabrication. The absorbers could be used to sense physical parameters such as temperature, pressure, density as well as they could be used for determining electromagnetic properties of materials and their characterization. In this work, an attempt has been made to explore the various possible applications of these sensors. Metamaterial-based sensors are very popular for its diverse applications in areas such as biomedical, chemical industry, food quality testing, agriculture. Split-ring resonators with various shapes and topologies are the most frequently used structures where the sensing principle is based on electromagnetic interaction of the material under test with the resonator. Overcoming the design challenges using metamaterial sensors involving several constraints such as cost, compactness, reusability, ease in fabrication, and robustness is also addressed.

Quad-Band Polarization-Insensitive Square Split-Ring Resonator (SSRR) with an Inner Jerusalem Cross Metamaterial Absorber for Ku- and K-Band Sensing Applications

“…MMAs have the potential used for sensing applications in the microwave range. Various devices have been proposed for different sensing applications, such as permittivity sensors, refractive index sensors, grin sensors, density sensors, temperature sensor, and glucose sensors [29,30,[32][33][34][35][36][37]. Moreover, K-and Ku-band frequencies can be applied for short-range microwave sensing [32,38,39].…”

Metamaterials and Their Application in the Performance Enhancement of Reconfigurable Antennas: A Review

“…Afterward, a sensor-based metamaterial absorber was also introduced having advantages of low cost, high sensitivity, easy fabrication, and good quality factor. These absorbers can be used to measure pressure, temperature, and density and to determine EM properties of materials [ 163 ].…”

Heuristic molecular modelling of quasi-isotropic auxetic metamaterials under large deformations

“…For instance, by adapting the interatomic distances between adjoining atoms it is possible to create a meta-material with bandgaps [74,75] or with varying wavelengths for dissipative purposes [76][77][78]; the auxetic property of the HM can be used to design energy dissipating layers for impact mitigation systems [77,79]; the material properties for the bonds can be modified aiming at a negative hygroscopic expansion ratio [80], among others. From a production standpoint, the possibility of physically reproducing the HM through a discrete assembly or a continuous one using additive manufacturing can be explored.…”
