“…This also decreases ink transfer, resulting in thinner ink layers and thus poorer conductivity and ink adhesion [8,10,11]. Despite the possibilities to easily affect and improve paper properties, higher electrical resistance is typically expected on papers than plastic foils [12]. Other flexible bio-based materials, such as biopolymer polylactic acid (PLA), silk fibroin, nanocellulose (NCF), and nanochitin, have also been developed for printed electronics applications where transparency and high smoothness of the flexible substrate are required [8,[13][14][15][16].…”

“…Paper-based electronics is a widely studied area. Paper has been evaluated as a substrate for thermochromic and electrochromic displays, resistive memory devices, transistors, capacitors, disposable radio frequency identification (RFID) tags, batteries, photovoltaic cells, and sensors and actuators [4][5][6]12,[17][18][19]. In recent years, the use of paper-based substrates in diagnostics, pharmaceutical, energy harvesting, and wearable applications has grown due to paper's high breathability consequently from porosity, flexibility, and sustainability [6,20].…”

Flexible plastic substrates are widely used in printed electronics; however, they cause major climate impacts and pose sustainability challenges. In recent years, paper-based electronics has been studied to increase the recyclability and sustainability of printed electronics. The aim of this paper is to analyze the printability and performance of metal conductor layers on different paper-based substrates using both flexography and screen printing and to compare the achieved performance with that of plastic foils. In addition, the re-pulpability potential of the used paper-based substrates is evaluated. As compared to the common polyethylene terephthalate (PET) substrate, the layer conductivity on paper-based substrates was found to be improved with both the printing methods without having a large influence on the detail rendering. This means that a certain surface roughness and porosity is needed for the improved ink transfer and optimum ink behavior on the surface of the substrate. In the case of uncoated paper-based substrates, the conductivity and print quality decreased by preventing the formation of the proper and intimate ink-substrate contact during the ink transfer. Finally, the re-pulpability trials together with layer quality analysis detected very good, coated substrate candidates for paper-based printed electronics competing with or even outperforming the print quality on the reference PET foil.

“…[50] Despite these substrate modifications, resulting printed patterns on paper show higher electrical resistance than on plastic. [51] Several techniques have been used to overcome this challenge, however even the most recent works still do not deeply analyze the effects of the pretreatment of the substrate and how those treatments affects the performance of the sensor in comparison with the substrate, e.g., electrochemical active area. [52][53][54][55] The motivation of this work is to understand the interfacial and micro/nanostructural morphology of several substrate treatment strategies, and study the relationship between these treatments and the development and performance of a full inkjet-printed sensor on a flexible and porous paper substrate, thereby obtaining different low-cost technical solutions for the sensor development.…”

Inkjet printing (IJP) technology allows the digital deposition of functional materials in microscale dimensions on a wide range of substrates, simplifying iterative design changes during the initial development stages. It is a noncontact approach that allows the mask-less deposition of materials owing to the precise control of picoliter volumes and a reduction in the overall time and cost of fabrication. Furthermore, IJP permits customized geometries and is compatible with low temperature processes. [5] Although screen-printed sensors are nowadays the most reported ones, [3] recent advances have demonstrated that inkjet-printed and paper-based electrochemical sensors provide a reliable solution for many applications. [4,6] Paper has emerged as a strong competitive substrate for diagnostic devices due to its attractive properties, including flexibility and conformability, hydrophilicity and high mechanical strength. [7][8][9][10] These excellent characteristics give paper excellent performance properties in the fabrication of paper-based devices. In addition, it is environmentally friendly, reusable/recyclable, biodegradable and biocompatible. [9,[11][12][13] For these reasons, paper-based sensors are increasingly gaining attention due to the global trend and commitment to "green electronics." Accordingly, this paper presents a flexible, disposable, and low-cost solution to develop sensors by IJP technology.Paper-based analytical devices (PADs) are in the spotlight for the development of flexible, disposable, and simpler devices taking advantage of their microfluidic properties. [14][15][16] PADs typically include an arrangement of hydrophilic/hydrophobic microstructures patterned in the paper using techniques such as wax printing, photolithography or chemical vapor-phase deposition among others. [17] In 2009, Dungchai et al. [18] demonstrated how the combination of PADs with an electrochemical sensor (ePAD) led to more reliable measurements than single microelectrode detection or colorimetric PAD sensors. [19] Electrochemical detection is an attractive alternative detection scheme for paper-based microfluidics due to its small size, portability, low cost, high sensitivity, and high selectivity by proper choice of detection potential and/or electrode material. [20] Therefore, electrochemical detection is widely used in analytical measurements ranging from clinical diagnostics to environmental biosensing. [21][22][23][24][25] To date, different strategies have been used to integrate electrodes on paper substrate. [26][27][28][29] In 2007, Whitesides' group introduced wax-based electrochemical paper-based devices. [30] The need for disposable, simpler, and accurate paper-based analytical devices represents an open research field that is focused on simpler fabrication methods. To achieve this, four feasible methodologies are proposed for the direct printing of an electrochemical sensor on a biodegradable paper substrate using commercial gold and silver inks, which are compatible with inkjet printing technology.

Pretreatment of particles obtained from lignocellulosic materials by steam explosion with indirect control by enzymatic hydrolysis has been studied. The dendromass pretreatment model has been applied for recycled fibreboard and particle board based on softwood. Their structure and chemical composition partly predetermine these lignocellulosic materials consisting of a mixture of spruce and fir particles also for bioethanol production. Optimum steam explosion temperature of 205 °C was determined based on the concentration of total monosaccharides — glucose, xylose and arabinose, among all experimentally prepared hydrolysates. This corresponds to basic conditions for fine disintegration of biomass to lignocellulosic structure with good holocellulose accessibility. Particles obtained from fibreboard and particle board primarily consisting of softwood without steam explosion pretreatment provide relatively low cellulose accessibility for commercial enzymes activity while monosaccharides concentration is partly reduced because of torrefaction at high temperatures. The concentration of monosaccharides in hydrolysates was determined for original sample and each steam explosion temperature. Based on the steam explosion conditions, the effect of severity factors was investigated to find optimum pretreatment conditions to increase accessibility of softwood cellulose and hemicelluloses. The identified optimum severity factor RO = 4.09 matches the optimum steam explosion temperature of 205 °C and the residence time of 10 minutes.
