Smart Textiles

Chinese researchers recently reported the discovery of a simple, scalable and low-cost method for producing smart fabrics that are more flexible and stretchable than current conductive textiles. The resulting materials could pave the way for smart garments that incorporate wearable technology and can better withstand the flexing, twisting and moisture that accompany a tough workout.

Conventional smart fabrics use techniques such as vapor deposition, electrospinning or spray coating to create film-coated yarns that are relatively stiff and brittle. In contrast, the new method utilizes the natural capillary action of fibers like cotton, nylon and polyester to make the materials absorb a solution of silver nanowires. When the solution evaporates, what is left behind is an even distribution of durable and highly conductive nanowires. Optical microscopic measurement is used to confirm uniform morphology and dispersal of wires throughout the fibers.

While this research is still at the proof-of-concept stage, the quest for a practical solution to creating garments that could collect biometric data, enhance our senses, or simply allow us to express ourselves in new ways remains ongoing.
