Comprehensive review demonstrates the mechanisms, fabrication, and integration bottlenecks of intelligent soft actuators, highlighting pathways toward hybrid and bioinspired robotic systems.

Key Points

To systematically review the operating principles, material architectures, and fabrication strategies of intelligent soft actuators while examining persistent performance trade-offs and future design directions.
Categorized and analyzed diverse actuation classes, including electroactive, dielectric, ionic, magnetoactive, photothermal, shape-memory, and fluidic systems.
Assessed modern manufacturing methods including multimaterial 3D printing, micro- and nanostructuring, interfacial engineering, and scalable molding.
Evaluated performance trade-offs across response dynamics, energy conversion efficiency, structural durability, and sensor integration feasibility.
Identified critical application bottlenecks in artificial muscles, biomedical tools, and controlled drug release stemming from limited material lifespan and strict biosafety demands.
Demonstrated persistent technical trade-offs that restrict the simultaneous realization of high output force, rapid response speeds, and large mechanical strain.
Identified hybrid actuation systems, bioinspired architectures, and co-designed integrated sensing as the primary pathways to enable closed-loop autonomous control.
