Conductive Yarn

By virtue of the light-weight, high conductivity, and extraordinary strength, carbon nanotube yarns (CNT yarn, CNTY) are attractive candidates for promoting wearable electronic textiles. However, the unstable conductivity of the CNTY due to piezoelectric characterization of the CNTs may severely affect the conductive performance of the CNTY that is woven into smart textiles. Herein, we report a highly stretchable and stable electro-conductive yarn fabricated by wrapping CNTY on the multifilament polyester yarn (MPY). The stretchable CNTY/MPY wrapping yarn exhibited not only significant-high tensile force (∼727.60 cN) but also ultra-high tensile strain (∼142.76%) compared to pristine CNTY (tensile force ∼211 cN, strain ∼20%). Furthermore, the CNTY/MPY wrapping yarn displayed very limited decrement (<0.5%) of resistance changes after cyclic loading and could still work even during ∼60% stretching. Moreover, this CNTY/MPY wrapping yarn presented steady-state temperature (205.5 °C) with a high quick electro-thermal response (with 1 s) when applied with 2 V voltage. In addition, the CNTY/MPY wrapping yarn could retain the electro-thermal stability when sewed into gloves, displaying low temperature-changes (<2%) under various deformations. Our work explored the potential applications of CNTY/MPY wrapping yarn for wearable smart textiles.

Manufacturing Techniques

Electronic textiles, also known as smart textiles or smart fabrics, are one of the best form factors that enable electronics to be embedded in them, presenting physical flexibility and sizes that cannot be achieved with other existing electronic manufacturing techniques. As part of smart textiles, e-sensors for human movement monitoring have attracted tremendous interest from researchers in recent years. Although there have been outstanding developments, smart e-textile sensors still present significant challenges in sensitivity, accuracy, durability, and manufacturing efficiency. This study proposes a two-step approach (from structure layers and shape) to actively enhance the performance of e-textile strain sensors and improve manufacturing ability for the industry. Indeed, the fabricated strain sensors based on the silver paste/single-walled carbon nanotube (SWCNT) layers and buffer cutting lines have fast response time, low hysteresis, and are six times more sensitive than SWCNT sensors alone. The e-textile sensors are integrated on a glove for monitoring the angle of finger motions. Interestingly, by attaching the sensor to the skin of the neck, the pharynx motions when speaking, coughing, and swallowing exhibited obvious and consistent signals. This research highlights the effect of the shapes and structures of e-textile strain sensors in the operation of a wearable e-textile system. This work also is intended as a starting point that will shape the standardization of strain fabric sensors in different applications.

Abstract This paper exhibits the electrothermal modelling and evaluation of Carbon Nanotube (CNT) based electrical interconnects for electronic devices. The continuum model of the CNT is considered and the temperature across interconnect is predicted for the given power. Finite element modelling software COMSOL Multiphysics is used to carry out the simulations. The results are compared with Al and Cu interconnects. An electrothermal analysis is also carried out to obtain the temperature for the given power for Single-Walled CNT, Double-Walled CNT, Triple-Walled CNT, and Multi-Walled CNT. Results show that the CNT interconnects performs better when compared to Al and Cu interconnects. The power withstanding capability of CNT is 68.75 times more than Al and 32.35 times more than Cu. Based on the transient analysis, the time taken by the CNT interconnects to reach a steady temperature is obtained as 0.007 ns. On the application of power, Cu and Al interconnects takes 0.1 ns to reach the steady-state temperature. The nanostructured CNT based electrical interconnects would play a considerable role in replacing Cu and Al electrical interconnect applications for micro and nanoelectronic devices.

MXenes, carbon nanotubes, and nanoparticles are attractive candidates for electromagnetic interference (EMI) shielding. The composites were prepared through a filtration technique and spray coating process. The functionalization of non-woven carbon fabric is an attractive strategy. The prepared composite was characterized using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and Raman spectroscopy. The MXene-oxidized carbon nanotube-sodium dodecyl sulfate composite (MXCS) exhibited 50.5 dB (99.999%), and the whole nanoparticle-based composite blocked 99.99% of the electromagnetic radiation. The functionalization increased the shielding by 15.4%. The composite possessed good thermal stability, and the maximum electric conductivity achieved was 12.5 S·cm−1. Thus, the composite shows excellent potential applications towards the areas such as aeronautics, mobile phones, radars, and military.

Fabric Production

Electronic or conductive textiles have attracted particular attention because of their potential applications in the fields of energy storage, supercapacitors, solar cells, health care devices, etc. Contrary to solid materials, the properties of textile materials such as stretchability, foldability, washability, etc. make the textiles ideal support materials for electronic devices. Therefore, in recent years, various conductive materials and production methods have been researched extensively to make the textiles conductive. In the present study, an alternative method based on imparting the conductivity to the fiber-based structure for the production of conductive textiles was established. Considering the contribution of unique characteristics of the fiber-based structure to the clothing systems, imparting the conductivity to the fibrous structure before yarn and fabric production may help to protect the breathable, lightweight, softness, deformable and washable of textile structure, and hence to improve the wearability properties of the electronic textiles. In the study, carbon black nanoparticles were selected as a conductive material due to low cost and easy procurable while cotton fiber together with other fiber types such as polyester, acrylic and viscose rayon fibers were used due to their common usage in the textile industry. In addition, various production parameters (CB concentration, feeding rate, etc.) were analyzed and the results indicated that the developed alternative method is capable to produce conductive yarns and electrical resistance of the yarns was about 94–4481 kΩ. The yarns had comparable yarn tenacity and breaking elongation properties, and still carried conductive character even after washing. In literature, there has been no effort to get conductivity in this manner and the method can be considered to be a new application for added-on or built-in future wearable electronics. Also, in the study, produced conductive yarns were used as a collector to gather the nanofibers onto the yarn to produce hybrid yarns enabling the production of functional textile products.

This paper presents a novel solution for monitoring incontinence status through the design and development of the intelligent incontinence pants by the use of conductive yarns and incorporating advanced circular seamless knitting technology. The produced textile incorporates wire and electrodes by conductive yarn working with a siren system which can monitor, sense and alert the wearer and care provider on the incontinence status in real time so as to reduce the need for manual checking and minimize patient care workload. The engineered stitches, yarn materials, and unique seamless knitting techniques provide soft handling, special fabric mechanisms, and tactile comfort of the resulting product. The electrical resistance of knitted conductive yarn demonstrated a stable performance in wet processing. Fitting body trials were conducted to estimate product dimension and configuration. This study allows us to explore further the potential applications of conductive yarn and seamless knitting technology in bio-functional and intelligent healthcare products and solutions through integrating multidisciplinary knowledge and techniques.
