“…Current work has deposited on to planar glass substrates, but more novelty is expected as researchers use AJP for non-planar and flexible substrates. Andrews et al [103] printed a capacitive sensor from a carbon nanotube ink that, when pressed to a material, exhibits a linear response between capacitance and material thickness. Another interesting application that uses similarly interdigitated AJP structures for electrostatic adhesion has been proposed for use in miniaturised robotics [104].…”

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.

“…The function of the annealing is mainly twofold: one is to evaporate the solvent used in solution‐processing alongside other impurities to ensure ideal layer quality, and the other is to partially or fully melt the separated nanoparticles together to get better conductivity or chemically convert the deposited precursor to a stable semiconductor layer via thermal energy. Currently there are two major thermal annealing methods: i) conventional thermal annealing via furnace, oven, or hotplate; ii) photothermal annealing via laser or flash lamp . The first annealing approach has been widely used for most printing applications like transistors or sensors with printed electrodes from Ag/Au nanoparticle inks due to the low‐cost and simplicity in implementation of such a method .…”

Printing techniques for the fabrication of diodes have received increasing attention over the last decade due to their great potential as alternatives for high‐throughput and cost‐effective manufacturing approaches compatible with both flexible and rigid substrates. Here, the progress achieved and the challenges faced in the fabrication of printed diodes are discussed and highlighted, with a focus on the materials of significance (silicon, metal oxides, nanomaterials, and organics), the techniques utilized for ink deposition (gravure printing, screen printing, inkjet printing, aerosol jet printing, etc.), and the process through which the printed layers of diode are sintered after printing. Special attention is also given to the device applications within which the printed diodes have been successfully incorporated, particularly in the fields of rectification, light emission, energy harvesting, and displays. Considering the unmatched production scalability of printed diodes and their intrinsic suitability for flexible and wearable applications, significant improvement in performance and intensive research in development and applications of the printed diodes will continuously progress in the future.

“…This technology, even if not yet commercialized, is already available: A fully printed sensor, made of metallic carbon nanotube ink, capable of noninvasive material thickness detection was already developed and tested (Andrews et al, 2017). By applying the sensors directly beneath the tread (within the tire), changes in the tread depth are able to be detected: This is a low-cost approach for monitoring changes in material thickness, using noninvasive printed sensors, applicable in monitoring tire wear by Internet-of-Things (IoT) technology.…”

“…In the article (Andrews et al, 2017) the authors declare that "this proof-of-concept experiment provides reinforcement to the applicability of these noninvasive material thickness sensors and demonstrates a different measurement technique to allow sensing despite the steel mesh in a car tire", but no detailed results are provided on the reliability of this tire monitoring methodology during their life cycle. Therefore, it is a method of direct measurement of tire wear, whose strengths are:…”

In the field of mobility and road transport, tires are components of a vehicle that play a decisive role in active safety. Monitoring tire conditions can affect different areas: Transport safety, optimization of cycles and maintenance costs and environmental protection. In fact, the tire wear check, possibly through the evaluation of the Remainig Useful Life (RUL), allows to meet many objectives: To ensure the necessary replacement of worn tires (safety target), to optimize the tire replacement cycles (maintenance target), avoid unnecessary early replacements (cost reduction target), reduce the amount of waste to be disposed of (environmental protection target). In this study two innovative methodologies, referable to technologies of Industry 4.0 field, are examined for the monitoring of tire wear: The first provides for direct monitoring through the use of "IoT" technology, the second provides for indirect monitoring through the use of "Big Data" technology. The scope and the limits of application are defined preliminarily, then the two methodologies are described according to the operating principle, in order to highlight merits and defects, finally a comparison of the two methodologies is provided. The proposed methodologies also allow to redesign the tires, developing new and safer products, with a flexible and integrated vision, which concerns the economic, social and environmental aspects from the perspective of managing the entire product life cycle (LCM-Life Cycle Management).
