Soft actuators have emerged as promising tools for environmental monitoring; however, most existing suffer from multistimuli cross-sensitivity and limited adaptability across various environments. Herein, we propose a bilayer soft actuator composed of graphene-doped polydimethylsiloxane (G@PDMS) layer poly(vinylidene fluoride) (PVDF) layer, capable effective deformation in both air aqueous environments while exhibiting selective responsiveness. The demonstrates responsiveness to organic solvents/vapors, thermal radiation, infrared (IR) radiation air, achieving bidirectional under stimuli with remarkable bending angle 630° load capacity 180 times its self-weight. In environments, the exhibits minimal response IR light but shows high selectivity rapid specific pollutants, time just 1.77 s dichloromethane. Leveraging these properties, developed series functional actuators─including Miura origami, airfoil, artificial muscle configurations─demonstrating their capability replicate complex movements. Moreover, water lily-inspired multienvironmental was designed effectively shield against underwater temperature fluctuations, light, nontarget solvent interference, showing cross-insensitivity potential real-time monitoring applications.
