“…They have been used in flexible electronics where minimum deformation would not damage the electrical conductivity. [27][28][29] However, for large bending and stretching deformations, AgNPs tend to form cracks and electrical conductivity is significantly deteriorated. 30 As a result, they are usually employed as a decoration material to enhance the performance of electrodes.…”

Purpose In flexible electronics applications, organic inks are mostly used for inkjet printing. Three-dimensional (3 D) printing technology has the advantages of low cost, high speed and good precision in modern electronic printing. The purpose of this study is to solve the high cost of traditional printing and the pollution emissions of organic ink. It is necessary to develop a water-based conductive ink that is easily degradable and can be 3 D printed. A nano-silver ink printed circuit pattern with high precision, high conductivity and good mechanical properties is a promising strategy. Design/methodology/approach The researched nano-silver conductive ink is mainly composed of silver nanoparticles and resin. The effect of adding methyl cellulose on the ink was also explored. A simple 3 D circuit pattern was printed on photographic paper. The line width, line length, line thickness and conductivity of the printed circuit were tested. The influence of sintering temperature and sintering time on pattern resistivity was studied. The relationship between circuit pattern bending performance and electrical conductivity is analyzed. Findings The experimental results show that the ink has the characteristics of low silver content and good environmental protection effect. The printing feasibility of 3 D printing circuit patterns on paper substrates was confirmed. The best printing temperature is 160°C–180°C, and the best sintering time is 30 min. The circuit pattern can be folded 120°, and the cycle is folded more than 60 times. The minimum resistivity of the circuit pattern is 6.07 µΩ·cm. Methyl cellulose can control the viscosity of the ink. The mechanical properties of the pattern have been improved. The printing method of 3 D printing can significantly reduce the sintering time and temperature of the conductive ink. These findings may provide innovation for the flexible electronics industry and pave the way for alternatives to cost-effective solutions. Originality/value In this study, direct ink writing technology was used to print circuit patterns on paper substrates. This process is simple and convenient and can control the thickness of the ink layer. The ink material is nonpolluting to the environment. Nano-silver ink has suitable viscosity and pH value. It can meet the requirements of pneumatic 3 D printers. The method has the characteristics of simple process, fast forming, low cost and high environmental friendliness.

“…Electrodes fabricated using IJP have been demonstrated to produce better stability and reproducibility when compared with conventional electrodes, in addition to being a rapid, user-friendly, and inexpensive fabrication technology. [30] Electrodes were also found to possess greater sensitivity than that fabricated via thin-film deposition for detecting hydrogen peroxide, due to the greater surface roughness of the electrode fabricated by IJP. [266] IJP operates with viscosities in the order of <100 mPa s, which is notably smaller than other extrusion-based AM technologies.…”

“…The primary focus for EC sensors has been on fabricating electrodes, where electrodes with complex structures provide enhanced electrochemical performance and reproducibility compared to conventional electrodes. [29,30] In addition, some AM technologies allow for nanopattern feature construction with greater precision than traditional fabrication technologies, and thus have the potential to address the mutually exclusive relationship between sintering and loss of nanofeatures that can impede redox mediating properties when utilizing metallic nanoparticles. [31] As highlighted in this review, AM is capable of fabricating other aspects of EC biosensors, such as electrochemical cells and printed circuit boards.…”

With the impending Industrial Revolution 4.0, the information produced by sensors will be central in many applications. This includes the healthcare sector, where affordable healthcare and precision medicine are highly sought after. Electrochemical sensors have the potential to produce affordable, high sensitivity and specificity, intuitive, and rapid point‐of‐care diagnostics. Underpinning these achievements is the choice of material and the fabrication thereof. In this review, the different types of materials used in electrochemical biosensors are reported, with a focus on synthetic conductive materials. The review demonstrates that there is an abundance of materials to select from, and compositing different types of materials further widens their applicability in biosensors. In addition, the fabrication of such materials using the state‐of‐the‐art of fabrication technology, additive manufacturing (AM), is also detailed. The need for compositing is evident in AM, as the feedstock for certain AM technologies is inherently nonconductive. Both material choice and fabrication technologies limitations are also discussed to highlight opportunities for growth. The review highlights how recent technological advancements have the potential to drive the healthcare industry toward achieving its primary goals.
