“…This technique thereby provides a means for obtaining realistic values of the contact resistance. It was reported that the electrical contacts between the warp and weft yarns were very sensitive to mechanical disturbance [2]. The contact resistance is the result of a huge number of microscopic real contacting spots created by the load between the crossing yarns.…”

“…It was stated that in more or less real-life situations, the contact resistance of interlacing multifilament silver-coated yarns will vary and this variation will depend on yarn, weave, and environmental factors. A new measurement of contact resistance will, therefore, be necessary each time one wishes to make a new fabric with conductive yarns [2]. The model developed by Gunnarsson [2] assumed that the yarns made contact only at the crossing point.…”

“…Oxides have higher resistivity which requires more effort for the signal to travel through the film [1]. An uneven distribution of the contact resistance could also alter the performance of a sensor or an antenna made up of the fabric [2].…”

The contact resistance of two interlacing electro-conductive yarns embedded in a hybrid woven fabric will constitute a problem for electro-conductive textiles under certain circumstances. A high contact resistance can induce hotspots, while a variable contact resistance may cause malfunctioning of the components that are interconnected by the electro-conductive yarns. Moreover, the contact robustness should be preserved over time and various treatments such as washing or abrading should not alter the functioning of the electro-conductive textiles. The electrical resistance developed in the contact point of two interlacing electro-conductive yarns is the result of various factors. The influence of diameter of the electro-conductive stainless steel yarns, the weave pattern, the weft density, and the abrasion on the contact resistance was investigated. Hybrid polyester fabrics were produced according to the design of experiments (DoE) and statistical models were found that describe the variation of the contact resistance with the selected input parameters. It was concluded that the diameter of the stainless steel warp and weft yarns has a statistically significant influence on the contact resistance regardless of the weave. Weft density had a significant influence on the contact resistance but only in case of the twill fabrics. Abrasion led to an increase in contact resistance regardless of the weave pattern and the type of stainless steel yarn that was used. Finally, a combination of parameters that leads to plain and twill fabrics with low contact resistance and robust contacts is recommended.

Conformable electrical systems integrated in textiles offer revolutionary possibilities. Textiles constitute an obvious choice as a multifunctional electronic platform, since they are worn and used to cover many surfaces around us. The primary focus of the emerging area of electronic textiles (e-textiles) is on developing transformative technologies to produce flexible, conformable, and large-area textile-based electronic systems. One of the main roadblocks to development of e-textiles is making (fiber-to-fiber) interconnects within textiles, with rigid semiconductor-based circuits and other devices, and efficiently routing these circuits. This problem is compounded by the need for the textile and other materials to withstand the stresses and strains of manufacturing and end-use. The fundamental challenge of forming

In this study, the impact of three different principles of surface activation techniques for polyamide fibers on the formation of conductive percolation during the subsequent electroless copper deposition process was investigated. The techniques used are (1) polyamide complexation using a solution mixture of calcium chloride, ethanol and water, (2) atmospheric plasma surface treatment and (3) grafting of 2‐hydroxyethylmethacrylate by radical induced polymerization. As a result, the percolation threshold was shifted to lower copper contents. The copper content required to form conductive structures was reduced ranged between 59% and 89%, depending on the activation techniques. Furthermore, the deposition time was reduced by 37%–57%, resulting in a faster build‐up of the percolation on the fabric. Changes in wetting behavior and substrate surface topography were identified to be the main reasons for these observations. While all applied surface activation techniques led to higher copper contents compared to unmodified reference, the atmospheric plasma modification led to the highest copper contents during the deposition process and a more uniform appearance of the metallised layer.Highlights Three different fiber surface activation methods are evaluated. Fiber surface activation increases wetting and polymer‐metal adhesion. Activated polymer surface leads to faster copper deposition and percolation. Atmospheric plasma modification is the most efficient technique.
