“…Microscopic images were taken on a digital microscope (Model: Keyence VHX-7000). From microscopic images, it is evident that some irregularities on edges are noticeable in the square non-metallic block shapes due to ink spreading, which is typical for the screen-printing method [32].…”

“…Because of their high conductivity and low loss, conductive inks including copper, graphene, and others, are widely employed to transfer the pattern upon the flexible plastic substrate. The main PE-based fabrication technologies are flexography printing, hotstamping, screen-printing, and ink-jet printing [32,33]. Despite the relatively low resolution of the printed pattern, which is in the order of a few tens of microns, printing THz devices with features on the order of the wavelength size remains adequate.…”

We employed the screen-printing method to fabricate terahertz (THz) frequency selective surfaces (FSS) featuring an inductive metallic checkerboard (i-MCB) pattern based on silver nanoparticles ink onto a flexible polyethylene terephthalate (PET) substrate. Analytical studies, along with simulations and experiments, were conducted to investigate the filtering characteristics of the printed FSSs, confirming their functionality as a band-pass filter. Subsequently, we demonstrated the reconfigurability of a two-layer system by vertically stacking two layers. This was achieved by systematically shifting the position of the second layer in the x or y-direction relative to the first layer. Experimental verification revealed a significant variation in normalized transmission, ranging from 94% to 6% at 0.15 THz for type-I:i-MCBs and 90% to 5% at 0.20 THz for type-II:i-MCBs, respectively. This study presents a simple scheme for a reconfigurable screen-printed i-MCB-FSS operating in the THz range. Consequently, our findings demonstrate that screen printing method can effectively be employed for the large-scale production of THz FSSs.

“…It is also environmentally beneficial as it produces less raw material waste than conventional methods [25,26]. It is striking that the high precision of additive manufacturing technique, i.e., printable electronics even allows their own non-contact inline inspection by printing THz FSS [27,28]. There have already been a few reports on THz devices made via additive manufacturing, including vortex phase plates [27], diffractive THz lenses [29], gradient-refractive-index lenses [30], band-pass filters [31,32], etc.…”

We designed and fabricated a terahertz (THz) frequency selective surface (FSS) based on two distinct additive manufacturing technologies, namely, printable electronics (PE) and three-dimensional (3D) printing. Silver nanoparticle ink was printed on a polyethylene terephthalate (PET) substrate utilizing a large-scale roll-to-roll industrial PE technique with a flexographic printed unit, while the 3D-printed THz FSS was fabricated based on a powder bed fusion-selective laser melting system. The filtering characteristics of both types of FSS were verified through calculation, simulation, and experiments. Furthermore, the rotational tuning approach was applied to two identical FSS to form reconfigurable FSS which could be defined as Moiré FSS. Based on the numerical results obtained, our proposed technique which used a PE-based Moiré FSS achieves a 58% modulation depth at 0.25 THz, while experimental verification found a modulation depth of 41% at 0.22 THz, confirming that its adoption is simple and cost-effective. To the best of our knowledge, this is the first demonstration of a Moiré reconfigurable printed FSS operating in the THz region.

“…The main advantage of additive manufacturing is the ability to add only the necessary quantity of materials for device production, which drastically decreases the produced waste, in contrast to subtractive processes used in conventional electronics [7,8]. The other attraction of PE is its fabrication process, which consists of three main steps: selection of printed materials and substrates, printing and then drying or sintering [9]. However, with the massive demand for PE, concerns about their harmful and irreversible contribution to the environment have grown [10].…”

Printed electronics (PE) is growing rapidly through innovation in several pathways: ink formulation, substrate improvement, printing and drying process optimization. All these developments are combining to enable the production of a new generation of PE devices that reduce e-waste. However, the main question of the recyclability of these devices is critical. This article is focused on (1) the industrial fabrication of recyclable substrates prepared by roll-to-roll printing using flexographic printing units to cover paper with shellac solution and (2) the environmental impact assessment of new development of PE. To investigate the performance of the produced substrate, a battery-less near-field communication antenna was printed with a flatbed screen printing using silver ink. The print quality, electrical resistance and the basic functional characterization of these paper-based antennas were investigated and reported. To validate the functionality of printed devices, a 2.5 × 2.5 mm2 electronic chip was integrated onto the printed device. In order to predict the future perspectives and development of the PE, environmental challenges of the ink and substrates, during the production and end-of-life phases, are explored and discussed.
