Summary: The corrosion mechanism and kinetics of silver-coated conductive yarn (SCCY) used for wearable electronics were investigated in a NaCl solution. It was found that silver reacts with chlorine ions to form silver chloride on the SCCY surface, which is then detached into the electrolyte, leading to electrical disconnect. Electrodeposition of gold in the longitudinal direction on SCCY, with partial electrodeposition in the radial direction, extends the electrical conducting lifetime despite increased corrosion rate. Results indicate that the cost-effective gold part-coating provides continuous current path until all silver underneath is detached.

Summary: Knitting provides structural versatility and malleability for the integration of conductive yarns in e-textiles, allowing for wider applications in wearables and interiors. This study investigates the washability and abrasion resistance of polymeric optical fibers (POFs) and silver-coated conductive yarn integrated knitted textiles with different loop structures, and their impact on the illuminative function. The experiments show that POFs and conductive yarns in the same fabric structure can withstand washing and abrasion, indicating their potential for mass market adoption in fashion and interior applications.

Summary: A foot pressure sensor was developed using conductive cotton yarn coated with Polydimethylsiloxane (PDMS) through embroidery technique. Modified cotton yarn was coated with reduced graphene oxide (rGO) to make it conductive, and then PDMS was applied as a protective layer. The yarn electrode was sewed into different fabrics using embroidery technique to assemble pressure sensors. The preparation process was characterized with scanning electron microscopy and Fourier Transform Infrared spectroscopy. The performance of single yarn electrodes and assembled devices were evaluated by measuring the short-circuit current signal under various applied forces and frequencies. The results demonstrate the successful application of the fabricated foot pressure sensor for monitoring basic human body movement.

Summary: A foot pressure sensor has been developed using conductive cotton yarn coated with Polydimethylsiloxane (PDMS) by embroidery technique. The cotton yarn was modified with a silane coupling agent and coated with rGO to make it conductive, and then coated with a PDMS sheath layer. The fabricated yarn electrode was sewn into different fabrics to form pressure sensors using embroidery technique. The performance of both single yarn electrodes and assembled devices was tested by measuring the short-circuit current under different frequencies and applied forces. The results demonstrate the successful application of the developed foot pressure sensor in monitoring human body movements.

Summary: This study investigated the relationship between functionality and comfort of conductive fabrics in smart clothing by examining changes in mechanical, electrical, and comfort properties based on blending ratio of conductive yarns. As the blending ratio of conductive yarn increased, weight, tensile strength, and bending rigidity increased while strain decreased. The addition of conductive yarn improved breathability but increased surface roughness.

Summary: In this article, a method for fabricating conductive tracks on polymer substrates using digital printing and laser processing is presented. A silver flake-based composite is printed onto a polycarbonate substrate using a jet-dispensing process, and the printed tracks are cured by a pyrometer-controlled laser beam source. The resistance and cross-sectional area of the conductive tracks are analyzed and compared to conventionally oven-cured samples. By using a laser instead of an oven, the resistance of the tracks can be reduced by a factor of 2, and the reproducibility of the achieved resistance is improved.

Summary: In recent years, there has been rapid growth in innovative technology based on conductive textile yarns. Nanocomposite-based wearable strain sensors show great promise for various applications, particularly in human body motion detection. However, improving the sensitivity of these strain sensors while maintaining durability remains a challenge. This study developed robustly wash durable and mechanically stable conductive textile yarns by encapsulating polydopamine-treated and two-dimensional nanostructured materials, such as reduced graphene oxide (rGO)-coated conductive cotton and polyester yarns, using polydimethylsiloxane (PDMS). The integration of these yarns into a knitted cotton glove and armband created a highly stretchable and flexible textile-based strain sensor for measuring finger and elbow movement. Truly wearable garments capable of recording proprioceptive maps are crucial for further advancements in this field.
