Flexible Stretchable Strain Sensor Based on LIG/PDMS for Real-Time Health Monitoring of Test Pilots

Sensors, Journal Year: 2025, Volume and Issue: 25(9), P. 2884 - 2884

Published: May 2, 2025

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.
