“…Aerosol jet printing atomizes the polymer solution enabling it to quickly dry on the substrate and reduce the coffee ring effect seen with other techniques that have slower drying times [12]. The use of aerosol jet printing has been previously demonstrated for depositing dielectric materials for both capacitor and TFTs [11,[39][40][41][42][43][44]. Several of these studies have highlighted the usefulness of aerosol jet printing for PVA specifically, as the dielectric material [39,41,42].…”

With the rise of the internet of things and applications such as smart packaging, the need for low cost, disposable temperature sensors with minimum environmental impact are critical. In this study, we report fully printed capacitive temperature sensors made from bio-degradable dielectric materials. All layers were aerosol jet printed and the areal capacitance was characterized at several temperatures between room temperature (22 ˚C) and 80 ˚C. Using a bilayer dielectric structure, a layer of poly(vinyl alcohol) was encapsulated with polycaprolactone through interfacial crosslinking to protect it against humidity. Various concentrations and layer amounts of poly(vinyl alcohol) were investigated, with the most effective capacitors consisting of a single layer of poly(vinyl alcohol) deposited from a 5.0 mg mL-1 solution followed by a layer of the UV-crosslink-able polycaprolactone deposited from 2.0 mg mL-1 solution, achieving a 43 ± 6% increase in areal capacitance at 80 °C when compared to room temperature, measured at a frequency of 501 Hz.

Aerosol jet printing (AJP) is a new non-contact direct writing technique designed to achieve precise and intricate patterns on various substrates. Specifically, the pneumatic AJP process breaks down the ink into fine particles, significantly reducing the risk of nozzle clogging and rendering it highly advantageous for industrial applications. This paper focuses on the optimization of the line electrode formation process using soluble silver clusters as the conductive ink, along with the aerosol formation procedure. The main parameters of the AJP process, namely sheath flow rate, atomizer flow rate, and dispensing speed, were identified and examined for their influence on line width and resistivity. Through this analysis, an operability window, including optimized conditions for printing high-quality lines using the AJP process, was established, along with a regression equation enabling the statistical estimation of line width. In summary, the outcomes of this investigation underscore the feasibility of an integrated printing system capable of precision control over line width, achieved through the optimization of AJP process parameters. Furthermore, it was established that pneumatic AJP offers robust process stability. The practical applicability of the proposed optimization techniques was assessed, highlighting their potential utilization in electrode formation processes within the electronic and display industry.
