“…Screen printing is also compatible with micro‐fabrication techniques for microchips and electronic devices. It is used to fabricate biosensing microchips, [ 146 ] piezoresistive sensors, [ 147 ] RFID transponders, [ 148 ] and others. Although this technique can simultaneously print the electrode and electrolyte materials thus making it a simple and efficient process, it requires the use of a mask to fabricate the required patterns and is hindered by limited mask resolutions.…”

platforms integrating microfluidics, electronics and various sensory components. This allows LOCs to offer all-in-one miniaturized laboratories solutions for a plethora of applications. A typical LOC system contains for instance microchannels and actuating components such as microvalves and microfluidic mixers for liquid sample handling, filtering and transport, in addition to microelectrodes, thermal elements, or optical apparatuses for measuring and sensing. LOC technology has in fact adopted most analytical (photo)(bio)(electro)chemistry methods and techniques, such as electrochemical sensing, [4] mass spectrometry, [5] thermal detection, [6] capillary electrophoresis, [7] electrochromatography, [8] infrared, [9] and Raman spectroscopies, [10] scattering, [11] refractive index, [12] surface plasmon resonance, [13] and fluorescence.

“…[5,6] In particular, it is difficult to replace the batteries in wireless sensor networks deployed in remote areas or inaccessible locations such as the A simple way to reduce the roughness and porosity of paper substrates for use in RF electronics is to employ additive surface treatment, such as a waterproof coating. The addition of a conductive inkjet, [30,31] or screen printing, [32,33] to paper can produce a surface that is smooth and non-wet with a fabrication resolution as high as 10 µm and high conductivity of 10 8 S m −1 . However, conductive material layers on the surface of paper generally have weak mechanical stability when subject to touching, bending, or folding.…”

deep sea, underground, chemical plants, environmental disasters areas, and agricultural farmland. [7] Radio frequency energy harvesting (RFEH) has emerged as a promising option for powering IoTbased devices due to the broad availability of radio frequency (RF) signals, which, despite their relatively low energy density, are accessible in places where other energy sources such as solar and thermal energy are unavailable or limited. [8][9][10] However, conventional RFEH systems have limitations in terms of their cost, size, weight, and foldability. As a result, many studies have attempted to combine novel fabrication methods and ambient RFEH to produce low-cost, light, small, and foldable power supply systems. [11][12][13][14] Cellulose paper is a promising substrate for the fabrication of RFEH systems that satisfy these requirements. Paper has recently gained significant attention as a component of electronics due to its abundance, disposability, recyclability, biocompatibility, light weight, cost-effectiveness, and flexibility. [15][16][17] Based on these advantages, paper or paper-like substrates have been utilized in a variety of applications ranging from basic electronic units to complicated electronic devices such as supercapacitors (SCs), [18,19] light-emitting diodes (LEDs), [20] transistors, [21] biofuel cells, [22] RF antenna, [23] and sensors. [24] However, it remains difficult to employ conventional methods for the fabrication of paper-based electronics in the development of integrated foldable RFEH systems that incorporate an RF antenna, RF/direct current (DC) rectifier, and energy storage unit. The main reason for this is the limitations associated with paper when seeking to fabricate a stable electrode due to its high porosity, hygroscopy, and surface roughness. [15] In general, the porosity and surface roughness of a substrate are important properties affecting the quality of a fabricated electrode because they can affect ink or particle penetration continuity and disrupt conductive paths if they are too high. [25] As a result, the roughness and porosity of paper substrates for electronic applications need to be reduced. [26,27] In particular, because RF electronics require a more stable and homogeneous substrate and higher conductivity than DC components, [28,29] untreated paper is generally not suitable for RF electronics. In addition, the hygroscopic nature of conventional paper hinders the complicated patterning required for RF electronics, such as the fabrication of uniform micro-sized lines, vias, and conductive patterning on both sides of paper. Radio frequency energy harvesting (RFEH) systems have emerged as a critical component for powering devices and replacing traditional batteries, with paper being one of the most promising substrates for use in flexible RFEH systems. However, previous paper-based electronics with optimized porosity, surface roughness, and hygroscopicity still face limitations in terms of the development of integrated foldable RFEH systems within a single sheet of paper....

“…An interesting trend in this regard is research that concentrates on printed antennas for conformal applications [ 7 , 8 ]. Common low-cost materials, such as paper [ 9 , 10 , 11 , 12 ], cardboard [ 13 ], textiles [ 14 ], and plastics [ 15 , 16 ] may be used as a printable substrate. Moreover, additive printing processes such as inkjet printing, screen printing, flexography, and gravure printing are considered simple, fast, and cost-efficient compared to traditional subtractive manufacturing technologies [ 17 , 18 , 19 , 20 ].…”

The Internet of Things (IoT) accelerates the need for compact, lightweight and low-cost antennas combining wideband operation with a high integration potential. Although screen printing is excellently suited for manufacturing conformal antennas on a flexible substrate, its application is typically limited due to the expensive nature of conductive inks. This paper investigates how the production cost of a flexible coplanar waveguide (CPW)-fed planar monopole antenna can be reduced by exploiting a mesh-based method for limiting ink consumption. Prototypes with mesh grids of different line widths and densities were screen-printed on a polyethylene terephthalate (PET) foil using silver-based nanoparticle ink. Smaller line widths decrease antenna gain and efficiency, while denser mesh grids better approximate unmeshed antenna behavior, albeit at the expense of greater ink consumption. A meshed prototype of 34.76×58.03mm with almost 80% ink reduction compared to an unmeshed counterpart is presented. It is capable of providing wideband coverage in the IMT/LTE-1/n1 (1.92–2.17 GHz), LTE-40/n40 (2.3–2.4 GHz), 2.45 GHz ISM (2.4–2.4835 GHz), IMT-E/LTE-7/n7 (2.5–2.69 GHz), and n78 5G (3.3–3.8 GHz) frequency bands. It exhibits a peak radiation efficiency above 90% and a metallized surface area of 2.46 cm2 (yielding an ink-to-total-surface ratio of 12.2%).
