“…[37] The loss tangent of the Teslin ® paper varied from 0.012 -0.024 over the measured frequency range, which was 3 -5 times lower than has been reported for standard cellulose-based paper. [5] This latter result was promising for the generation of efficient (high quality factor) antennas and passive microwave components.…”

“…[1][2][3][4] Reports of inkjet-printed metalized devices on flexible substrates range from antennas to sensors to thin film transistors to RFID tags. [1,[5][6][7][8][9][10][11][12][13][14] The patterned metallization of substrates using inkjet printing is commonly conducted with inks comprised of a dispersion of metallic nanoparticles within a carrier fluid tailored to achieve a desired viscosity and wetting behavior for a particular substrate. [1][2][3][4] Coatings on the metallic nanoparticles are used to ensure that the nanoparticles remain well dispersed in the ink.…”

A scalable, low-cost process for fabricating copper-based microwave components on flexible, paper-based substrates is demonstrated. An inkjet printer is used to deposit a catalyst-bearing solution (tailored for such printing) in a desired pattern on commercially-available, recyclable, non-toxic (Teslin ® ) paper. The catalystbearing paper is then immersed in an aqueous copper-bearing solution to allow for electroless deposition of a compact and conformal layer of copper in the inkjet-derived pattern. Meander monopole antennas comprised of such electroless-deposited copper patterns on paper exhibited comparable performance as for antennas synthesized via inkjet printing of a commercially-available silver nanoparticle ink. However, the solutionbased patterning and electroless copper deposition process avoids nozzle-clogging problems and costs associated with noble metal particle-based inks. This process yields compact conductive copper layers without appreciable oxidation and without the need for an elevated temperature, post-deposition thermal treatment commonly required for noble metal particle-based ink processes. This low-cost copper patterning process is readily scalable and may be used to generate a variety of copper-based microwave devices on flexible, paper-based substrates.

“…A commercial silver nanoparticle based ink from Sigma Aldrich (product 719048) with an average particle size of 150 nm is printed to form metal tracks on the 3D printed dielectric. As inkjet printing is highly dependent on the substrate type, it is necessary to characterize the ink on a particular substrate in order to obtain an accurate measure of the printing performance, as is done in [9] for the paper substrate. Before printing, it is necessary to treat the surface of the substrate with acetone in order to remove unwanted contaminants such as grease and oils.…”

“…Inkjet printing of only dielectric materials has been used to fabricate RF structures [7,8]. On the other hand, inkjet printing of only metals has been shown to fabricate antennas on conventional planar substrates [9,10]. There are not many reports that show integration of inkjet printed metal and dielectric to realize RF structure.…”

In this paper, we propose a textile metamaterial absorber that using screen printing technology. A unit cell of the proposed absorber is motivated from the commercial Chanel logo for wearable applications. The complex impedance of the designed unit cell is analyzed by full-wave simulation. To verify its performance, the proposed metamaterial absorber is fabricated where the silver conductive ink is screen printed on an ordinary textile. From experimental results, the absorptivity of the proposed absorber is around 93 % at 10. . 메타물질 흡수체는 무한히 주기적인 단위구조로 구현되 기 때문에 필요한 공간에 적용시키기 쉽다. 게다가 기존 의 페라이트와 같은 전자파 흡수체와는 달리, 부피가 작 으며 얇은 두께임에도 불구하고 100 %에 가까운 흡수율 을 가질 수 있다 [2] . 이러한 장점을 바탕으로 메타물질 흡 수체는 다양한 응용 분야에 적용되고 있으며, 특히 곡면 형 구조에 적용시키기 위해 PDMS(polydimethylsiloxane) [3] , 필름 [4] , 폴리이미드(polyimide) [5] 와 같은 유연성을 가지는 기판을 활용한 유연한 흡수체가 활발히 연구되고 있다.한편, 웨어러블 디바이스에 적용시키기 위해 직물에 전도성 물질을 사용하여 전자 기기를 구현하는 연구가 이루어지고 있다. 예를 들면 웨어러블 전자소자의 에너지 밀도를 증가시키기 위한 yarn 슈퍼커패시터가 제안되었 으며 [6] , 인간의 생체 신호를 실시간으로 감시할 수 있는 센서가 제안되었다 [7] . 이러한 웨어러블 디바이스는 일반 직물 원단에 전도성 도체 폴리머 섬유를 구현하거나 [8] , ⓒ
