Abstract: ABSTRACT Flexible strain sensors (FSS) that offer a broad sensing range and enhanced sensitivity are essential for advancing wearable technology. In this work, highly FSS was developed by embedding Ti3C2Tx MXene and multi‐walled carbon nanotubes (MWCNTs) into elastic styrene‐ethylene‐butylene‐styrene (SEBS) melt‐blown nonwoven fabric. Benefiting from the synergetic effect of two‐dimensional MXene nanosheets and one‐dimensional MWCNTs, the composite nonwoven fabric exhibited high electrical conductivity and an extensive strain sensing range from 0% to 268% with high sensitivity (maximum gauge factor of 126,526.15) and reliable long‐term stability. The sensor, constructed from the composite nonwoven fabric, was adeptly employed to detect motions across various human body parts, including the elbow joint, wrist joints, knuckle, knee, and Achilles tendon, demonstrating encouraging potential for applications in wearable technology.
