“…39 As demonstrated in Figure 5, the distinctive bands of S0 owing to cellulose macromolecule, appeared at 3349 cm −1 (O−H stretch), 2950 cm −1 (C−H stretch), 1400 cm −1 (C−H wagging), 1350 cm −1 (C−H bending), 1610 cm −1 (CO stretch), and 1100 cm −1 (C−O stretch). 25 Otherwise, the characteristic peaks of S1 (Figure 5) showed that upon the addition ofthe absorption peaks from the cellulose macromolecule, the absorption peaks of the alginate were shifted to a higher wavelength in the alginate/starch and appeared at 1640, 1410, and 1300 cm −1 . Those peaks were attributed to stretching vibrations of asymmetric and symmetric peaks of carboxylate anions (COO − ).…”

Utilization of natural products in medical textiles toward multifunctional applications without side effects is an extremely motivating goal. Herein, a novel, eco-friendly procedure was developed to introduce multifunctional cotton gauze fabrics using guava leaf powder extract. Biocompatible microcapsules composed of guava leaf powder extract and starch core and calcium-alginate (Ca-alginate) outer membrane were developed. The current strategy involved the identification and assessment of the bioactive compounds extracted from guava leaf via ultrasonic technique. Then, the guava leaf extract was loaded within a matrix of sodium alginate/starch and coated onto the cotton gauze fabrics. The morphological properties of both blank and treated cotton gauze fabrics were characterized by Fourier-transform infrared spectroscopy (FT−IR) and scanning electron microscopy (SEM). The antibacterial activity of the developed cotton gauze was evaluated against E. coli as Gram negative pathogenic bacteria and S. aureus as Gram positive pathogenic bacteria using the agar diffusion and bacterial counting methods. Furthermore, the treated cotton gauze fabrics were also used to conduct further studies toward the production of wound healing dress. The treated cotton gauze demonstrated remarkable antimicrobial, antioxidant, UV shielding, and wound healing properties. As a result, the current study presents a new simple approach to design smart cotton gauze for multifunctional medical and healthcare applications employing bioactive extract from sustainable plant waste.

“…The use of metal oxide and nanoparticles on the fabric/fiber surfaces plays a remarkable role on the performance and the appearance of the final product. Performance fabrics may have dual or multifunctionality like antimicrobial activity, UV protection function, self-cleaning, and thermal stability properties, and they are used to increase the fabric’s versatility. − Different methods have been established for synthesis of metal oxides and nanoparticles. Polymer-NPs are prepared followed by the spinning process, and exositu − and in situ synthesis of NPs into the fibers surface were used. − Lately, the use of the plant parts as green obtainable and renewable sources for in situ incorporation of NPs was prominently commanded more attention by researchers. − In the present study, we develop for the first time, to the best of our knowledge, an environment-friendly green and cost-effective process for advanced functionalization of cellulosic fabrics/fibers with bioactive compound extracted from OP as agro-waste product.…”

The objective of this study is to explore, identify, and evaluate the bioactive compound extracted from orange peels (OP) via ultrasonic method as potential eco-friendly agent for multifunctional cellulosic fabrics/fibers. The innovative strategy involved two approaches. (1) A closely prepared surface modification procedure for the production of multifunctional viscose fibers was successfully developed by an eco-friendly in situ synthesis of Ag, ZnO, and ZnO/Ag nanoparticles (NPs) using phenolic compounds extracted from OP. The treated viscose fibers are endowed with remarkable antimicrobial, antioxidant, UV protection, as well as photo catalytic self-cleaning activity properties. (2) The microcapsulation and application of limonene extracts from OP as insect-repellent agent for application in textile field. On the basis of the resultant promoting data, the OP extract can be considered as a promising cheap source that can be employed to develop multifunctional finishing textiles. Therefore, this study introduces a novel simplified approach to design innovative cellulosic fabrics/fibers as viable materials for functional sportswear, medical, and fashion clothing using active extracts from sustainable orange peels.

“…Cotton is an especially attractive option for wearable medical and telehealth sensors because cotton is hypoallergenic [ 167 ], ecofriendly [ 168 , 169 , 170 ], lightweight [ 170 ], cost-efficient [ 168 , 170 , 171 ], sustainable [ 168 ], and easily laundered [ 169 , 171 ]. In addition to these properties, cotton serves as a “blank canvas” that may be treated with antimicrobial agents—a property that is desirable when monitoring wound healing [ 167 , 172 , 173 , 174 , 175 , 176 , 177 , 178 , 179 ].…”

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.
