Flexible wearable strain sensors demonstrate promising application prospects in health monitoring, human-machine interaction, motion tracking, and the detection of human physiological signals. Although laser-induced graphene (LIG) materials have been extensively utilized these scenarios, traditional types LIG are constrained by intrinsic limitations, including discontinuous conductive networks electromechanical responsive hysteresis. These limitations hinder their applications micro-strain scenarios. Consequently, enhancing performance LIG-based has become a crucial priority. To address this challenge, we developed novel MXene/LIG composite featuring optimized interfacial coupling effects through systematic enhancement LIG. The flexible sensor fabricated using exhibits exceptional performance, an ultra-low sheet resistance 14.1 Ω, high sensitivity 20.7, limit 0.05%, rapid response time approximately 65 ms. improvements significantly enhance responsiveness sensitivity. Furthermore, remarkable stability under varying tensile strains, particularly showing outstanding repeatability across 2500 cyclic tests. Notably, when applied to pilot monitoring MXene/LIG-based demonstrates robust capability detecting body movement signals such as micro-expressions joint movements. This establishes highly effective technological solution for real-time pilots’ states during operational
