Self-Powered Ultrastretchable Microstructured Intelligent Sensing Technology Based on Tactile Perception of Limb Movement

By leveraging the complementary advantages of a highly elastic functional film and conductive fillers, a surface microstructured Ecoflex/CNTs/MXene composite film TENG was fabricated through microstructure engineering and synergistic modification involving carbon nanotubes (CNTs) and two-dimensional transition metal carbides (MXene). Under the combined enhancement of optimized material selection, physical blending modification, and structured surface design, the device achieved an open-circuit voltage output of 223.5 V under a load of 35 N, a frequency of 1 Hz, and 100% tensile strain. Meanwhile, it exhibited an ultrahigh tensile strain of 594.07%. Additionally, a self-powered energy supply system was developed based on this surface microstructured composite film TENG, laying a technical foundation for the advancement of highly stretchable self-powered electronic devices and intelligent motion interactive systems.
