Fiber filaments have an extremely wide range of applications; depending on their material composition, structure, and function, they can be utilized across numerous fields, including textiles, medicine, aerospace, construction, electronics, and environmental protection.
Wearable Technology and Biomedicine
Health Monitoring: A team at Xidian University has developed an electronic fiber with a diameter of just 50 micrometers. This fiber can be woven into clothing to provide real-time monitoring of heart rate, electromyography (EMG) signals, and physical activity status; it demonstrates robust resistance to motion artifacts, outperforming traditional gel electrodes.
Neuromodulation: These fibers can be implanted into the peripheral sciatic nerves of rats to deliver precise electrical stimulation, achieving a success rate of nearly 100%. This technology provides a foundational basis for applications such as brain-computer interfaces and spinal cord stimulation.
Flexible Electronics: The fibers can function as flexible RF antennas and inductive coils. When woven into textiles, they maintain stable electrical conductivity-even under conditions involving bending, stretching, or high humidity-and are capable of driving electronic components such as LEDs.
High-Performance Structural Materials
Aerospace: T1200-grade carbon fiber-boasting a tensile strength of 8,000 MPa and a density just one-quarter that of steel-has achieved mass production at the hundred-ton scale. It is utilized in commercial spaceflight, the "low-altitude economy," humanoid robots, and other applications, enabling weight reductions exceeding 10%.
Civil Engineering Reinforcement: Carbon fiber fabric is employed for the tensile and seismic reinforcement of bridges, tunnels, and structural beams and columns, offering key advantages such as high strength, lightweight properties, and corrosion resistance.
Ballistics and Protection: Regenerated silk fibers and synthetic spider silk possess a toughness capable of surpassing that of Kevlar, finding application in products such as body armor and spacesuits.
