Abstract Flexible sensors have emerged as a promising tool in applications ranging from pilot physiological monitoring to motion capture and complex training environments. However, conventional approaches often face inherent limitations, such as susceptibility to electromagnetic interference, instability in humid or sweat-rich conditions, and restricted multifunctional integration. To overcome these challenges, we present a flexible sensor based on a multifunctional MXene/LIG composite structure. By combining surface-modified MXene with laser-induced graphene (LIG), we developed a robust conductive framework characterized by hierarchical porosity. Thanks to this innovative design, the sensor achieves exceptional multifunctional performance. It exhibits high electromagnetic shielding effectiveness of 31.5 dB through synergistic reflection and absorption, demonstrates strong hydrophobicity with a contact angle of 151.1$^\circ$, and delivers enhanced thermal conductivity. These features enable accurate monitoring of operational movements in simulated cockpit environments while ensuring durable performance under complex aviation requirements. Moreover, this design strategy offers a novel pathway for advancing high-performance flexible sensors, opening new opportunities in wearable electronics, healthcare monitoring, and intelligent human-machine interaction systems.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
