“…Since this technique is based on non-contact aerosol jet deposition, it can print complex patterns on non-planar substrate as it is less affected by substrate conditions. Recently, complex conformal surfaces (3D printed electronics) printing have been demonstrated by controlling the position in z-direction of the writing head over the substrate [142,143]. Various materials (conductive polymers, organic semiconductors, dielectrics, novel materials, bio-materials) can be deposited by using an aerosol jet [144,145].…”

Direct printing methods have been used as manufacturing tools for printed electronics applications due to their cost effectiveness. In this review, the piezo-driven inkjet is discussed in detail since it is a mature technology and suitable for the production printing of printed electronics. In addition, other printing methods are considered for using higher viscosity ink and for producing smaller printed feature size. Various direct printing methods are compared in terms of jet mechanism, printing algorithm, and their applications. In particular high resolution printing methods using high viscosity inks, such as electrohydrodynamic jet, aerosol jet and micro-plotter are reviewed. To understand the recent status of industrial printing applications, display (liquid crystal display and organic light emitting diode) materials and printing issues are discussed. Finally, a brief overview of nano-particle metal based conductive inks is included because these inks have been widely used for printed electronics applications.

“…Among the existing printing methods, aerosol jet printing is the most promising technology because it allows the formation of functional elements with a minimum lateral size of up to 10 microns [7][8][9] both on flat and curved substrates [10,11]. This technology has been applied for the manufacture of transistors [12], sensors [13][14][15], solar cells [16], microheaters [17], microantennas [18,19] and interconnects [20]. Previous studies of this technology relied mainly on the formation of thin-film microstructures due to the need for the manufacture of planar electronic devices.…”

In this work, we studied the formation of conductive silver lines with high aspect ratios (AR = thickness/width) > 0.1 using the modernized method of aerosol jet printing on a heated silicon substrate. The geometric (AR) and electrical (resistivity) parameters of the formed lines were investigated depending on the number of printing layers (1–10 layers) and the temperature of the substrate (25–300 °C). The AR of the lines increased as the number of printing layers and the temperature of the substrate increased. An increase in the AR of the lines with increasing substrate temperature was associated with a decrease in the ink spreading as a result of an increase in the rate of evaporation of nano-ink. Moreover, with an increase in the substrate temperature of more than 200 °C, a significant increase in the porosity of the formed lines was observed, and as a result, the electrical resistivity of the lines increased significantly. Taking into account the revealed regularities, it was demonstrated that the formation of silver lines with a high AR > 0.1 and a low electrical resistivity of 2–3 μΩ∙cm is advisable to be carried out at a substrate temperature of about 100 °C. The adhesion strength of silver films formed on a heated silicon substrate is 2.8 ± 0.9 N/mm2, which further confirms the suitability of the investigated method of aerosol jet printing for electronic applications.

“…A schematic of u-AJP can be seen in figure 1(B), with a magnified view of how a sheeth of inert gas guides the aerosolized ink out of the nozzle, helping to prevent clogging. There are numerous benefits to AJP over IJP for device fabrication, including the ability to print inks with a wide range of viscosities, greater ease with printing on non-planar surfaces [35], printing high aspect ratio materials [36], and the deposition of smaller volumes [37]. Previous reports demonstrate the utility and versatility of AJP by fabricating complex transistor devices via a lowtemperature printing process [38], developing a flexible pressure sensing array [33], and the creation of organic solar cells [39].…”

Aerosol jet printing of biological inks by ultrasonic delivery

Printing is a promising method to reduce the cost of fabricating biomedical devices. While there have been significant advancements in direct-write printing techniques, non-contact printing of biological reagents has been almost exclusively limited to inkjet printing. Motivated by this lacuna, this work investigated aerosol jet printing of biological reagents onto a nonfouling polymer brush to fabricate in vitro diagnostic (IVD) assays. The ultrasonication ink delivery process, which had previously been reported to damage DNA molecules, caused no degradation of printed proteins, allowing printing of a streptavidin-biotin binding assay with sub-nanogram mL −1 analytical sensitivity. Furthermore, a carcinoembryogenic antigen (CEA) IVD was printed and found to have sensitivities in the clinically relevant range (limit of detection of approximately 0.5 ng mL −1 and a dynamic range of approximately 3 orders of magnitude). Finally, the multi-material printing capabilities of the aerosol jet printer were demonstrated by printing silver nanowires and streptavidin as interconnected patterns in the same print job without removal of the substrate from the printer, which will facilitate the fabrication of mixed-material devices. As cost, versatility, and ink usage become more prominent factors in the development of IVDs, this work has shown that aerosol jet printing should become a more widely considered technique for fabrication.
