“…Can the artificial axons function as wearable and washable conductors for active textiles? Many stretchable conductors have been developed to enable wearable active textiles [14][15][16][17][18][19][20] , but making them washable is challenging [21][22][23] . Among recent advances, the technology of silver nanowire/PDMS composite stands out.…”

ABSTRACT:The emergence of stretchable electronics and its potential integration with textiles have highlighted a challenge: textiles are wearable and washable, but electronic devices are not. Many stretchable conductors have been developed to enable wearable active textiles, but little has been done to make them washable. Here we demonstrate a new class of stretchable conductors that can endure wearing and washing conditions commonly associated with textiles.Such a conductor consists of a hydrogel, a dissolved hygroscopic salt, and a butyl rubber coating.The hygroscopic salt enables ionic conduction, and matches the relative humidity of the hydrogel 2 to the average ambient relative humidity. The butyl rubber coating prevents the loss and gain of water due to the daily fluctuation of ambient relative humidity. We develop the chemistry of dip coating the butyl rubber onto the hydrogel, using silanes to achieve both the crosslink of the butyl rubber and the adhesion between the butyl rubber and the hydrogel. We test the endurance of the conductor by soaking it in detergent while stretching it cyclically, and by machinewashing it. The loss of water and salt is minimal. It is hoped that these conductors open applications in healthcare, entertainment, and fashion.3

“…Polymers and their composites have attracted much interest in recent years. Their applications range from fiber reinforced composites‐based large parts for aerospace, wind energy, and automotive industries, to nanocomposites such as electronic skins (e‐skin), flexible and stretchable electronics, light‐emitting diodes (LEDs), and textiles . The fabrication process of these components or devices requires curing the polymer with the correct processing parameters (temperature, time, etc.)…”

Interdigital sensors (IDS) have received great attention for production monitoring of polymers over the past decade. However, conventional IDS are limited by high noise to environment due to the dual side access of the sensor, low nominal capacitance, and sensitivity. In this study, a shielded IDS fabricated by flexible circuit board (FCB) technology is presented to overcome these challenges. Compared to conventional sensors, the environmental dependence of the new sensor is minimized by the copper shield. Furthermore, nominal capacitance of at least 350% higher, and an increase of sensitivity per unit area are achieved. To demonstrate the capabilities of the new IDS, a FCB comprising the proposed sensor is fabricated, attached to a mould, and successfully applied for in situ real‐time production monitoring of an epoxy resin. The resulting flexible sensor is noninvasive towards the fabricated parts, and measures the key stages along the production process. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.

“…10,11 For industrial applications, methods such as coating, screen printing, ink-jet printing and various thin-film deposition techniques are suggested in the literature for producing conductive threads with such insulated layers. [12][13][14] However, no attention has been paid to using welding and bonding techniques for the manufacture of textile signal lines.…”

This paper presents optimization of the hot air welding process parameters for the formation of textile transmission lines and the electro-conductive properties of these manufactured transmission lines. A dedicated manufacturing set-up has been developed to allow a reliable and flexible textile signal transmission line at adequate conductivity. In order to manufacture textile transmission lines, different welding parameters with different conductive yarns and welding tapes were considered. Layered fabric structures consisting of textile transmission lines and fabrication tolerances were determined, as well as electro-conductive properties for welded samples. It was found that the choice of welding parameters, depending on the materials used for the formation of textile transmission lines, is extremely important for obtaining good electro-conductive properties. In addition, welding tapes and thermoplastic materials play an important role during the set-up of welding process parameters. Results statistically confirmed that welding tapes with conductive yarns can significantly cause a variety of changes in the signal qualities of welded textile transmission lines. The obtained results based on conductivity and signal-to-noise ratios are really promising for the manufacturing of e-textile transmission lines via hot air welding technology.
