“…However, after printing, the organic material should be removed by post-processing treatments, e.g., sintering, annealing or simple air drying, to allow physical contact between the metal particles to form a continuous path connection [ 32 ]. Due to the porous structure and rough surface of fibrous substrates, the uniform deposition of conductive (nano)ink is still a great challenge, leading to the inconsistency in electrical conductivity of the fabrics [ 30 ]. By far, the most commonly used metals present in metallic conductive inks are Ag [ 35 , 36 , 37 ], followed by Au [ 38 , 39 , 40 ].…”

The rapid growth in wearable technology has recently stimulated the development of conductive textiles for broad application purposes, i.e., wearable electronics, heat generators, sensors, electromagnetic interference (EMI) shielding, optoelectronic and photonics. Textile material, which was always considered just as the interface between the wearer and the environment, now plays a more active role in different sectors, such as sport, healthcare, security, entertainment, military, and technical sectors, etc. This expansion in applied development of e-textiles is governed by a vast amount of research work conducted by increasingly interdisciplinary teams and presented systematic review highlights and assesses, in a comprehensive manner, recent research in the field of conductive textiles and their potential application for wearable electronics (so called e-textiles), as well as development of advanced application techniques to obtain conductivity, with emphasis on metal-containing coatings. Furthermore, an overview of protective compounds was provided, which are suitable for the protection of metallized textile surfaces against corrosion, mechanical forces, abrasion, and other external factors, influencing negatively on the adhesion and durability of the conductive layers during textiles’ lifetime (wear and care). The challenges, drawbacks and further opportunities in these fields are also discussed critically.

“…Examples of them are the CNT-based heaters presented by Ilanchezhiyan et al [20], which follows a dip coating method, or the spin-coating process reported by Zhout et al [21]. Other printing techniques, such as screen-printing, are also suitable for the fabrication of CNT heaters, as reported by Sadi et al [22]. However, inkjet printing presents unique advantages over these previous approaches since, in addition to be suitable for the fabrication of large area flexible heaters and roll-to-roll processes, it also allows the pattering of the substrates without the use of neither screens nor masks, all this with a better resolution when compared with their counterparts [23].…”

This work demonstrates a cost-effective manufacturing method of flexible and fully printed microheaters, using carbon nanotubes (CNTs) as the heating element. Two different structures with different number of CNT layers have been characterized in detail. The benchmarking has been carried out in terms of maximum operating temperature, as well as nominal resistance and input power for different applied voltages. Their performances have been compared with previous reports for similar devices, fabricated with other technologies. The results have shown that the heaters presented can achieve high temperatures in a small area at lower voltages and lower input power. In particular, the fully printed heaters fabricated on a flexible substrate covering an area of 3.2 mm2 and operating at 9.5 V exhibit a maximum temperature point above 70 °C with a power consumption below 200 mW. Therefore, we have demonstrated that this technology paves the way for a cost-effective large-scale fabrication of flexible microheaters aimed to be integrated in flexible sensors.

The design and development of textile-based capacitive sensors requires the implementation of textile capacitors with a determined capacitance. One of the main techniques to obtain these sensors is the screen-printing of conductive and dielectric inks on textiles. This paper investigates the fabrication parameters that have the most influence when designing and implementing a screen-printed capacitive sensor. In this work, a textile has been used directly as the dielectric part, influencing sensitively the value of the permittivity and the thickness of the dielectric of the capacitor. These are two fundamental parameters for the estimation of its capacitance. The choice of the conductive ink, its viscosity and solid content, as well as printing parameters, such as printing direction, also impact on the manner for obtaining the electrodes of the capacitive sensor. Although the resulting electrodes do not represent an important parameter for the estimation of the capacitance, it determines the selection of fabrics that can be printed. As a result of the investigation, the paper provides a guideline to choose the materials, such as fabrics or inks, as well as the printing parameters, to implement e-textile applications based on projected capacitive technologies. The experiments carried out on different fabrics and inks have provided results with capacities of less than 60 pF, the limit where the sensors based on capacitive technologies are located.
