“…The most common structure is the splitring resonator (SRR). In [131], an inkjet-printed SRR metamaterials array is presented as a low-cost solution intended to operate at the lower frequencies of the X-band potentially for frequency-selective microwave-shielding applications. The design consists of an arrangement of 3 × 20 × 15 SRRs uniformly and periodically distributed.…”

The field of flexible electronics is undergoing an exponential evolution due to the demand of the industry for wearable devices, wireless communication devices and networks, healthcare sensing devices and the technology around the Internet of Things (IoT) framework. E-tex tiles are attracting attention from within the healthcare areas, amongst others, for providing the possibility of developing continuous patient monitoring solutions and customized devices to accommodate each patient’s specific needs. This review paper summarizes multiple approaches investigated in the literature for wearable/flexible resonators working as antenna-based systems, sensors and filters with special attention paid to the integration to flexible materials, especially textiles. This review manuscript provides a general overview of the flexible resonators’ advantages and drawbacks, materials, fabrication techniques and processes and applications. Finally, the main challenges and future prospects of wearable resonators are discussed.

“…Recently, inkjet printing technology has attracted the interest of many researchers, as it enables fast, low-cost, and easy fabrication of many radio-frequency and microwave components [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Successfully fabricated samples of antennas [4,7,8,[12][13][14], radio-frequency identification tags [1,2,17,18], metamaterials [5,9,10,15,16], as well as frequency-selective structures and surfaces [3,6,11] have been demonstrated in the literature, using both special material printers and conventional inkjet printers that are modified accordingly [12]. When employing very low-cost inkjet printing setups, which involve standard printers loaded with metal-based inks, fabrication errors need to be considered carefully, while these errors often put limitations in the design procedures [14].…”

“…Typical conductivity issues can partially be mitigated via post-processing (e.g., heat curing after printing), and very good flexibility can be achieved by selecting proper ink types (e.g., metal/liquid ratio) and substrates (e.g., the type of the photograph paper). It has been shown that flexible, very low-cost, and environmentally friendly components can be fabricated in such optimized fabrication setups [15], whereas the structures should still be carefully designed and often retuned due to the inherent limitations in printing resolution.…”

We present the design and computational simulation of multiband, polarizationindependent, and thin frequency-selective structures for microwave frequencies and their fabrication via a very low-cost inkjet-printing procedure. The structures are constructed by periodically arranging unit cells that consist of U-shaped resonators, while polarization-independency is achieved by applying rotational arrangements. Various configurations are obtained by considering double and single U-shaped resonators, as well as rotational and complementary relationships between the corresponding unit cells on the top and bottom surfaces. We observe that complementary arrangements provide resonances with better quality, particularly by allowing the smaller resonators to operate as desired. Measurements on the fabricated samples demonstrate the feasibility of both effective and very low-cost inkjet-printed frequency-selective structures with multiband and polarization-independent characteristics.
