“…In recent years, many researchers have investigated inkjet printing as a new deposition method to fabricate CNT films [71–73]. Different printing technologies to deposit CNTs on various substrates were subject to investigation, such as aerosol printing [74–76], screen printing [77] and contact printing [78]. Results show that using printing techniques has potential for fabricating low cost CNT devices and sensors [71].…”

Compared with traditional conductive fillers, carbon nanotubes (CNTs) have unique advantages, i.e., excellent mechanical properties, high electrical conductivity and thermal stability. Nanocomposites as piezoresistive films provide an interesting approach for the realization of large area strain sensors with high sensitivity and low manufacturing costs. A polymer-based nanocomposite with carbon nanomaterials as conductive filler can be deposited on a flexible substrate of choice and this leads to mechanically flexible layers. Such sensors allow the strain measurement for both integral measurement on a certain surface and local measurement at a certain position depending on the sensor geometry. Strain sensors based on carbon nanostructures can overcome several limitations of conventional strain sensors, e.g., sensitivity, adjustable measurement range and integral measurement on big surfaces. The novel technology allows realizing strain sensors which can be easily integrated even as buried layers in material systems. In this review paper, we discuss the dependence of strain sensitivity on different experimental parameters such as composition of the carbon nanomaterial/polymer layer, type of polymer, fabrication process and processing parameters. The insights about the relationship between film parameters and electromechanical properties can be used to improve the design and fabrication of CNT strain sensors.

“…The AJ method utilizes a mist of NP inks directed by a carrier gas, and can print inks with viscosities up to 1000 cP and feature sizes down to 10 lm. Furthermore, it has already been used to manufacture biosensors, 10 capacitive sensors, 11 transistors, 12 solar cells, 13,14 electronic interconnects, 15 and 3-D antenna structures. 9 The particle size in the inks used in the AJ method is typically <500 nm and has a printing standoff height of 5 mm, 9 enabling the production of electronic circuits on complex 3-D surfaces.…”

Printed electronics has emerged as a versatile eco-friendly fabrication technique to create sintered nanoparticle (NP) films on arbitrary surfaces with an excellent control over the film microstructure. While applicability of such films for high-temperature applications is not explored previously, herein we report the high-temperature electrical stability of silver (Ag) metal NP films fabricated using an Aerosol Jet based printing technique and demonstrate that this behavior is dictated by changes in the film microstructure. In-situ high temperature (24-500 C) impedance spectroscopy measurements show that the real part of the impedance increases with increasing temperature up to 150 C, at which point a decreasing trend prevails until 300 C, followed again by an increase in impedance. The electrical behavior is correlated with the in-situ grain growth of the Ag NP films, as observed afterwards by scanning electron microscopy and X-ray diffraction (XRD), and could be tailored by controlling the initial microstructure through sintering conditions. Using combined diffraction and spectroscopic analytical methods, it is demonstrated the Aerosol Jet printed Ag NP films exhibit enhanced thermal stability and oxidation resistance. In addition to establishing the conditions for stability of Ag NP films, the results provide a fundamental understanding of the effect of grain growth and reduction in grain boundary area on the electrical stability of sintered NP films.

“…Almost all inks or dispersions able to form an aerosol with liquid droplets can be applied for aerosol jet printing. This makes aerosol jet printing also a valuable tool to test novel material inks for functional materials such as carbon nanotube dispersions (Jones et al 2010). In particular, the application in silicon solar cell production seems promising.…”
