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.

Dr. Elias Torres Alonso, Research Scientist at Graphenea and former PhD student in Professor Craciun's team at Exeter, added: "This new research opens up the gateway for smart textiles to play a pivotal role in so many fields in the not-too-distant future. By weaving the graphene fibers into the fabric, we have created a new technique to all the full integration of electronics into textiles. The only limits from now are really within our own imagination."

This new research used existing polypropylene fibers - typically used in a host of commercial applications in the textile industry - to attach the new, graphene-based electronic fibers to create touch-sensor and light-emitting devices.

The new technique means that the fabrics can incorporate truly wearable displays without the need for electrodes, wires of additional materials.

Professor Saverio Russo, co-author of this study and researcher at the University of Exeter's Physics department, added: "The incorporation of electronic devices on fabrics is something that scientists have tried to produce for a number of years, and is a truly game-changing advancement for modern technology."

Dr Ana Neves, co-author and also from Exeter's Engineering department, added: "The key to this new technique is that the textile fibers are flexible, comfortable and light, while being durable enough to cope with the demands of modern life."

The international collaborative research includes experts from the Center for Graphene Science at the University of Exeter, the Universities of Aveiro and Lisbon in Portugal, and CenTexBel in Belgium.
