In the rapidly advancing era of intelligent technology, flexible strain sensors are emerging as a key component in wearable electronics. Laser-induced graphene (LIG) stands out promising fabrication method due to its rapid processing, environmental sustainability, low cost, and superior physicochemical properties. However, stretchability conformability LIG often limited by substrate material, hindering application scenarios requiring high deformation. To address this issue, we propose high-performance stretchable sensor fabricated generating on polyimide (PI) using laser induction subsequently transferred onto polydimethylsiloxane (PDMS). The resultant demonstrates an ultra-low detection limit (0.1%), response time (150 ms), wide range (40%), retains stable performance after 1000 stretching cycles. Notably, has been successfully applied real-time monitoring civil aviation test pilots during flight for first time, enabling accurate physiological signals such pulse, hand movements, blink frequency. This study introduces unique innovative solution health pilots, with significant implications enhancing safety.

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
