“…Eco‐conscious green values encourage the incorporation of abundant carbon‐based materials into TFT devices where possible. [ 177 ] This, in addition to low material cost and the possibility for low‐temperature solution processing, has motivated the emergence of print‐patterned carbon‐based S/D materials for oxide TFTs. For instance, patterning of single‐walled carbon nanotubes (SWCNTs) was demonstrated by spray coating through a shadow mask onto underlying In 2 O 3 semiconductor ( Figure a) resulting in flexible TFT devices which tolerated 1 mm bending radius and folding strain of 26.8% while maintaining the charge carrier mobility at over 79% of its initial value after 5000 cycles of folding in both parallel and perpendicular directions.…”

mechanical flexibility, higher charge-carrier mobility than that of organic materials or amorphous silicon, and low processing temperature as compared to amorphous and polycrystalline silicon TFTs. [18][19][20][21] Parallel to the achievements of metaloxide TFTs, organic materials, carbon nanotubes (CNTs), and 2D materials have also been constantly developed. For recent reviews, see refs. [22,23]. The material approaches differ in their characteristics such as charge-carrier type (electrons or holes), charge-carrier mobility, environmental and electrical stability, mechanical flexibility, operation voltage, thermal budget of processing, technology readiness level for high-throughput fabrication, and sustainability (environmental footprint of materials and processes). There are also approaches that combine different material classes, for example, to implement complementary logic by combining the predominantly n-type oxide TFTs with p-type organic TFTs. [24] In this paper, we focus on the metal-oxide TFTs that are among the highest-performing alternatives for flexible thin-film devices that can be patterned by printing and that have already reached the maturity of being used in product fabrication (e.g., flat-panel displays). [2] The first metal-oxide-based TFT employed tin oxide (SnO 2 ) as the semiconductor and was invented by Klasens et al. in 1964, opening the door for research into transparent metal oxide TFTs. [25] Owing to the technology and material-processing limitations at that time, only a few studies focused on this area until 2003. During that year, zinc-oxide-based (ZnO) TFTs with mobility of µ = 2.5 cm 2 V −1 s −1 were successfully manufactured by Hoffman et al., Carcia et al., In the same year, Nomura et al. made a breakthrough with the first use of the quaternary-oxide semiconductor IGZO in a single-crystalline form to fabricate the TFTs, rather than some more conventional binary oxides such as ZnO, indium oxide (In 2 O 3 ), and SnO 2 . This kind of device that required annealing at 1400 °C displayed better electrical properties than its binary counterparts, with 80 cm 2 V −1 s −1 mobility and a 10 6 on/off ratio. [29] The following year in 2004, they reported flexible TFTs fabricated at room temperature on polymer film based on amorphous IGZO (a-IGZO) with saturation mobility of ≈6-9 cm 2 V −1 s −1 . [30] The discovery of a-IGZO raised substantial interest in research on amorphous metal-oxide TFTs and their low-temperature Metal-oxide-semiconductor-based thin-film transistors (TFTs) are exploited in display backplanes and X-ray detectors fabricated by vacuum deposition and lithographic patterning. However, there is growing interest to use scalable printing technologies to lower the environmental impact and cost of processing. There have been substantial research efforts on oxide dielectric and semiconductor materials and their interfaces. Materials for the source/ drain (S/D) contact electrodes and their interface to the semiconductor have received less attention, particularly concerning the usa...

“…[22][23][24] The attractiveness of organic electronic materials is reflected in the possibility of their customized synthesis processes. 25,26 Moreover, their suitability for large scale production using solution cast (even roll-to-roll (R2R) and printing) thin films [27][28][29] on various substrates 30 at low temperatures 31,32 may truly be the revolutionizing event of the electronics technology. 33 Materials employed in such applications include both small molecule semiconductors, as used for example in organic light emitting diode displays (OLEDs) 34 and solution processible polymeric organic semiconductors for organic solar cells 35,36 and field effect transistors fabrication.…”

“…Given this, the chosen manufacturing and printing processes of new electronics is directly influenced by the properties of the new materials and corresponding ink properties, and therefore a simple substitution of a new material often leads to significant changes in the printing parameters. Although there are many options for sustainable dielectrics [6], there are few examples of printed electronics sensors fabricated using sustainable materials [7,8]. Efforts have been made to demonstrate the printability of such sustainable materials with several printing methods allowing for direct writing for quick and simple customization [6,[9][10][11][12][13][14][15].…”

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.
