“…However, these electrodes were sufficient to detect the P wave, QRS complex, and for heart monitoring. Saleh et al [72] produced textile-based flexible ECG sensors with graphene oxide, and a reduction process was carried out to obtain reduced graphene oxide cotton electrodes (rGOC). They experimented with various dipping times ranging from 1 min to 30 min to obtain the best possible conductivity.…”

“…They were washed at 40 • C for 63 min and up to 10 wash cycles at 1000 rpm in a normal household machine. Saleh et al [72] produced textile-based flexible ECG sensors with graphene oxide, and a reduction process was carried out to obtain reduced graphene oxide cotton electrodes (rGOC). The conductivity of these electrodes was above 70% of the original value after five wash cycles.…”

E-textiles is a new hybrid field developed with the help of the integration of electronic components into our daily usage of textile products. These wearable e-textiles provide user-defined applications as well as normal textile clothing. The medical field is one of the major leading areas where these new hybrid products are being implemented, and relatively mature products can be observed in the laboratory as well as in commercial markets. These products are developed for continuous patient monitoring in large-scale hospital centers as well as for customized patient requirements. Meanwhile, these products are also being used for complex medical treatments and the replacement of conventional methods. This review manuscript contains a basic overview of e-textile systems, their components, applications, and usages in the field of medical innovations. E-textile systems, integrated into customized products for medical needs, are discussed with their proposed properties and limitations. Finally, some recommendations to enhance the e-textile system’s integration into the medical field are argued.

“…Such drawbacks, however, are generally based on the use of cotton in sportswear or in stretch sensing applications, but cotton fabrics have been used as substrates for health care monitoring. For example, because of its low price point, flexibility, launderability, and light weight, cotton has been used as a substrate for different wearable electrocardiograms [ 181 , 182 , 183 , 184 , 185 , 186 ].…”

Fatigue Testing of Wearable Sensing Technologies: Issues and Opportunities

et al. 2021

View full text Add to dashboard Cite

Standards for the fatigue testing of wearable sensing technologies are lacking. The majority of published fatigue tests for wearable sensors are performed on proof-of-concept stretch sensors fabricated from a variety of materials. Due to their flexibility and stretchability, polymers are often used in the fabrication of wearable sensors. Other materials, including textiles, carbon nanotubes, graphene, and conductive metals or inks, may be used in conjunction with polymers to fabricate wearable sensors. Depending on the combination of the materials used, the fatigue behaviors of wearable sensors can vary. Additionally, fatigue testing methodologies for the sensors also vary, with most tests focusing only on the low-cycle fatigue (LCF) regime, and few sensors are cycled until failure or runout are achieved. Fatigue life predictions of wearable sensors are also lacking. These issues make direct comparisons of wearable sensors difficult. To facilitate direct comparisons of wearable sensors and to move proof-of-concept sensors from “bench to bedside,” fatigue testing standards should be established. Further, both high-cycle fatigue (HCF) and failure data are needed to determine the appropriateness in the use, modification, development, and validation of fatigue life prediction models and to further the understanding of how cracks initiate and propagate in wearable sensing technologies.

“…[15][16][17] The most common ways to make textiles more functional are the coating of conductive metal on fabric by evaporation of metal, dipping in functional solution, incorporating functional materials such as carbon materials, incorporating metal nanomaterials into textiles, and wax printing. 3,[18][19][20][21][22][23] Most of the time, these methods are time-consuming and financially inviable. Moreover, the integration of electronic components into textiles in a realistic manner while maintaining the inherent flexible nature and breathability of textiles remains a challenge.…”
