Electronic textiles (e-textiles) are being developed because of their potential applications in wearable and flexible electronics. However, complex procedures and chemical agents are required to synthesize carbon-based e-textiles. Pyroprotein-based e-textiles, obtained by the pyrolysis of silk proteins, consume large amounts of time and energy due to the high-temperature process (from 800 to 2800 °C). In this study, we report a novel method of fabricating pyroprotein-based electronic yarns (e-yarns) using microwave irradiation. Microwaves were applied to pyroprotein treated at 650 °C to remove numerous heteroatoms in a short time without the high-temperature process and chemical agents. The structural modulation was confirmed by Raman spectroscopy and X-ray photoelectron spectroscopy. We found a reduction in heteroatoms and enlargement of the carbon region. The temperature-dependent resistance was well explained by the fluctuation-induced tunneling model, which also showed structural modification. The electrical conductivity of the fabricated e-yarns was comparable to that of pyroprotein-based e-textiles heat-treated at 1000 °C (order of 10 S/cm) and showed electrical stability under bending.

Women sports wearer's comfort and health are greatly impacted by the breast movements and resultant sports bra compression to prevent excessive movement. However, as sports bras are only made in universal sizes, they do not offer the right kind of support that is required for a certain activity. To prevent this issue, textile-based strain sensors may be utilized to track compression throughout various activities to create activity-specific designed sports bras.

Seawater batteries (SWBs) are green aqueous power sources with great potential in marine applications. So far, SWBs are mainly built on rigid substrates, which hinders their adaptability to marine textile applications. Herein, we constructed a rechargeable yarn-shaped SWB consisting of nickel hexacyanoferrate (Ni-HCF)-modified carbon yarn (positive electrode), glass fiber diaphragm, and polyimide (PI)-modified carbon yarn (negative electrode).

Article Synopsis
- The study focuses on the substantial impact arthritis conditions have on First Nations Peoples, who suffer more than non-First Nations Peoples and require culturally relevant health information for better support.
- Utilizing a mixed-methods approach, the research included interviews with Aboriginal individuals about their needs for arthritis education and reviewed existing clinical practice guidelines for high-quality content.
- Findings from 30 Aboriginal participants led to recommendations for educational resources, emphasizing the effects of arthritis, access to care, and management strategies tailored to their cultural context.

Composites manufactured with textiles weaved with commingled yarns using PLA (polylactic acid) and PCL (polycaprolactone) fibres are promising candidates for connective tissue engineering. In this work, textiles were fabricated using PLA/PCL commingled yarns in a ratio of 3 to 1, which were subsequently consolidated by compression moulding to produce solid composite plates. Specimens were extracted from the composite plates and submitted to degradation testing by immersion in PBS fluid (phosphate-buffered saline) at different periods.

Thread-based microfluidics, which rely on capillary forces in threads for liquid flow, are a promising alternative to conventional microfluidics, as they can be easily integrated into wearable textile-based biosensors. We present here advanced textile-based microfluidic devices fabricated by machine stitching, using only commercially available textiles. We stitch a polyester "Coolmax®" yarn with enhanced wicking abilities into both hydrophobic fabric and hydrophobically treated stretchable fabric, that serve as non-wicking substrates.
