“…This has been more thoroughly discussed in the Ag system by Seifert et al at 200°C and above for >30-minute intervals [31]. Numerous publications [31,55,[69][70][71] have shown that increased annealing temperature or time leads to increased densification of the metal film, which is consistent with well-known ripening phenomena in crystal grain growth.…”

Printing methods such as additive manufacturing (AM) and direct writing (DW) for radio frequency (RF) components including antennas, filters, transmission lines, and interconnects have recently garnered much attention due to the ease of use, efficiency, and low-cost benefits of the AM/DW tools readily available. The quality and performance of these printed components often do not align with their simulated counterparts due to losses associated with the base materials, surface roughness, and print resolution. These drawbacks preclude the community from realizing printed low loss RF components comparable to those fabricated with traditional subtractive manufacturing techniques. This review discusses the challenges facing low loss RF components, which has mostly been material limited by the robustness of the metal and the availability of AM-compatible dielectrics. We summarize the effective printing methods, review ink formulation, and the postprint processing steps necessary for targeted RF properties. We then detail the structure-property relationships critical to obtaining enhanced conductivities necessary for printed RF passive components. Finally, we give examples of demonstrations for various types of printed RF components and provide an outlook on future areas of research that will require multidisciplinary teams from chemists to RF system designers to fully realize the potential for printed RF components.

Aerosol Jet Printing (AJP) is an emerging contactless direct write approach aimed at the production of fine features on a wide range of substrates. Originally developed for the manufacture of electronic circuitry, the technology has been explored for a range of applications, including, active and passive electronic components, actuators, sensors, as well as a variety of selective chemical and biological responses. Freeform deposition, coupled with a relatively large stand-off distance, is enabling researchers to produce devices with increased geometric complexity compared to conventional manufacturing or more commonly used direct write approaches. Wide material compatibility, high resolution and independence of orientation have provided novelty in a number of applications when AJP is conducted as a digitally driven approach for integrated manufacture. This overview of the technology will summarise the underlying principles of AJP, review applications of the technology and discuss the hurdles to more widespread industry adoption. Finally, this paper will hypothesise where gains may be realised through this assistive manufacturing process.

“…A formulation of a suitable ink is a critical phase, as the performance or quality of the printing process strongly depends on the ink. A low tendency for sedimentation and properly adjusted behaviour of the liquid carrier matrix are essential for a reliable printing process [9].…”

In this paper, resistive strain gages designed and fabricated in inkjet printing technology with three different silver nanoparticle inks are presented. Inks have different Ag content (15, 20 or 25 wt%) and solvents (water type or organic type). Strain gages were printed on a 50 ?m thick polyimide and 140 ?m thick PET-based substrate with different printer types (professional and desktop). All printed sensors have the same size (17 mm ? 5 mm). To determine the change of resistance due to bending of the steel beam, tensile tests were performed up to 1500 microstrains. Due to performed cycles of loading and unloading of the steel beam, gauge factor and stability of the response of the strain gages are measured. Resistance change was measured with Keithley SourceMeter 2410. For acquisition of measured data, in-house software tool was developed. Measured gauge factors of the sensors are in the range between 1.07 and 2.03 (depending on a used ink, substrate and printer). Results of this research indicate the strain gages with good GF can be produced even with low-cost equipment, such as desktop printer EPSON C88+ and PET-based substrate.
