Abstract Soft actuators with multi‐stimuli response have shown promising applications in soft intelligent robots. However, most are limited by the unidirectional actuation and self‐perception capabilities. Here, a bilayer self‐sensing actuator bidirectional is proposed, which showed exceptional actuation, of temperature moisture, smart solar panel. The layer consisted powerful hygroscopic sensitivity poly(vinyl alcohol) (PVA), poly(sodium styrene sulfonate) (PSS), conductive carbon black (CB). structural hydrophobic polyurea (PUU). bent to one side under NIR or stimulation (curvature reaches 3.8 cm −1 ) opposite moisture −4.6 ). Moreover, various bionic robots, weightlifting, selective grasping robots demonstrated. Simultaneously, owing CB gradient, sensing can detect movement different bending directions fast speed (82 ms). In addition, when increased, panel downward cleaned debris. Upon sunshine, faced sun maximized power output. More interestingly, monitor its degree orientation. proposed paved way for advancements artificial intelligence
