Researchers at NUS have developed SHINE fibres, offering self-healing, light-emitting, and magnetic properties for advancements in robotics, wearable technology, and smart textiles.
A unique light-emitting fibre with self-healing and magnetic properties has been developed at the National University of Singapore (NUS). The scalable hydrogel-clad ionotronic nickel-core electroluminescent fibre (SHINE), offers a unique blend of flexibility, wireless operability, and durability. Capable of self-repairing after damage while retaining nearly full brightness, this fibre opens new possibilities for smart textiles and robotics.
The fibre combines a nickel core for magnetic responsiveness with a light-emitting zinc sulphide layer and a hydrogel electrode. This design allows the fibre to be manipulated with magnets and recover its structure through heat-induced interactions at 50°C. “Our SHINE fibre achieves luminance of 1068 cd/m², far surpassing typical indoor lighting requirements,” remarked Benjamin Tee, associate professor and research leader, NUS.
The research represents a collaboration between NUS’s department of materials science and engineering and its institute for health innovation & technology (iHealthtech). With the ability to be woven into textiles or integrated into robotic systems, the fibre caters to a broad audience, including manufacturers of wearable technology, developers of advanced robotics, and researchers in human-machine interaction. Its multifunctionality makes it particularly attractive to industries aiming to create more adaptive, sustainable, and responsive solutions.
Light-emitting fibres have emerged as promising tools in fields like robotics and wearable technology. However, conventional fibres are often fragile and energy intensive. The SHINE addresses these limitations by integrating multifunctionality into a single scalable device. “Its ability to self-repair enhances sustainability by extending the usability of damaged fibres,” noted Dr Fu Xuemei, the first author and researcher, NUS.
The fibre’s potential applications include wearable displays and soft robotic devices. Magnetic actuation enables it to navigate tight spaces and perform complex movements while signalling optically in real time. This feature adds a new dimension to human-robot interactions, making them more intuitive and dynamic.
Looking ahead, the research team aims to enhance the fibre’s magnetic precision for advanced robotic tasks. They also envision embedding sensors for environmental monitoring, paving the way for next-generation smart textiles. With its versatility and resilience, the SHINE fibre represents a significant step forward in sustainable material innovation.
