A groundbreaking 3D stretchable electronic strip has been developed by researchers, promising to revolutionize wearable electronic textiles. Led by Nottingham Trent University’s Medical Technologies Innovation Facility in collaboration with industry partner Kymira Ltd, the research heralds a new era for embedded electronic devices in clothing, particularly in healthcare and elite sports.
Published in Scientific Reports, the study highlights significant advancements over existing technologies. The strip’s unique 3D structure, formed into a helical ribbon, endows it with unparalleled flexibility and stretchability, allowing it to bend in multiple directions and stretch up to half its original size—a crucial feature for applications in medical compression garments and sportswear that require unrestricted movement.
The researchers showcased prototypes of LED and temperature-sensing helical e-strips, demonstrating both functionality and durability. The design incorporates a rubber cord for structural support, mitigating damage from buckling, and ensures compatibility with clothing and washability.
Dr. Yang Wei, an expert in electronic textiles and electronic engineering at Nottingham Trent University and the principal investigator, remarked, “We’ve introduced a novel 3D helical strip concept for embedded electronics in e-textiles. Through design definition, prototype development, mechanical testing, and functional validation, we’ve unlocked a realm of possibilities for future applications in healthcare and elite sports.”
Lead author Jessica Stanley, a research fellow at the university’s Medical Technologies Innovation Facility and Department of Engineering, explained, “Our innovation adapts the age-old concept of using helices to create stretchable metal wires into a modern context. Unlike previous uses limited to interconnects or single components, our approach integrates flexible circuitry with complex circuits within a stretchable helix, ensuring compatibility with the dynamic demands of e-textile products.”
The technology has already been patented, paving the way for swift adoption by industry, anticipating rapid advancements in wearable electronic textiles.
