Graphene-based yarn to enable advanced wearable e-textiles

Researchers at the National Graphene Institute (NGI) have created a method to produce scalable graphene-based yarn. Such e-textiles may have great potential for sportswear, healthcare, aerospace, and fitness applications, and so are attracting research attention worldwide.

Graphene-based yarn to be used for advanced wearable e-textiles

Integrating textile-based sensors into garments in the manufacturing process is still time-consuming and complex. It is also expensive non-biodegradable, unstable, metallic conductive materials are still being used. Now, the NGI researchers have developed a process that has the potential to produce tonnes of conductive graphene-based yarn. It is possible to do this using current textile machinery without any addition to production costs. The produces graphene-based yarn is also said to be flexible, cheap, biodegradable, and washable.

The program, funded by the Welsh Government as part of its European Development Fund, is intended to benefit industry in Wales through the development of new concepts and advanced functionalized inks using Haydale’s advanced materials.

Garmor creates extra strong polymeric coatings and innovative conductive fibers

Garmor, manufacturer of low-cost graphene oxide, rGO and developer of innovative GO production methods, recently developed a graphene-enhanced polymeric coating with a 390% reported improvement in tensile strength. Garmor stated that it is already marketing this technology as it has already been fielded and used in commercial applications. Here's a video showing side-by-side testing of the original polymer (left) and the graphene-enhanced polymer (right) shown at 4X normal speed.

In addition, Garmor announced the development of an innovative process for converting insulating polymeric fibers into electrically conductive fibers with minimal cost and no waste products. The method has resulted in composites with single-digit graphene loadings delivering conductivity as high as .023 S/cm. Garmor sees such performance as ideal for wearable sensors and other applications that require integrated approaches to solving weight and measurement issues.

Exeter team designs graphene e-fibers with touch-sensing and light-emitting functionalities for smart textiles

An international team of scientists, led by Professor Monica Craciun from the University of Exeter's Engineering department, has reported a new technique to create fully electronic fibers that can be incorporated into the production of everyday clothing. The researchers believe that the discovery could revolutionize the creation of wearable electronic devices for use in a range of every day applications, as well as health monitoring, such as heart rates and blood pressure, and medical diagnostics.

Currently, wearable electronics are achieved by essentially gluing devices to fabrics, which can often mean they are too rigid and susceptible to malfunctioning. The new research avoids this by integrating the electronic devices into the fabric of the material, by coating electronic fibers with light-weight, durable components that will allow images to be shown directly on the fabric.
