This paper describes a stimuli-responsive microfiber-shaped hydrogel actuator with a porous surface layer. By using cellulose nanofibers as a sacrificial template material, we formed nanoscale pores on the surface of the microfiber in gentle condition, enabling the rapid response to external stimuli because the formed nanopores can work as pathways of fluid between inside and outside of the microfiber. We analyzed the formed nanopores by scanning electron microscope (SEM) and confirmed that the nanoporous hydrogel micro-actuator responded faster than the non-porous one. Our cellulose nanofiber-based nanoporous forming approach could be widely applied to polymer-based soft robotics and biomedical soft actuators because of its gentle and biocompatible processes.
