Polymeric hydrogel
actuators refer to intelligent stimuli-responsive hydrogels that could
reversibly deform upon the trigger of various external stimuli. They have thus
aroused tremendous attention and shown promising applications in many fields
including soft robots, artificial muscles, valves and
so on. After a brief introduction of the driven forces that contribute
to the movement of living creatures, we overview the design principles and
development history of hydrogel actuators, then this tutorial review is focused
on summarizing the diverse anisotropic structures of hydrogel actuators,
presenting the promising applications of hydrogel actuators, and highlighting
the development of multi-functional hydrogel actuators. Finally, the existing
challenges and future perspectives of this exciting field will be discussed.
