Area of Science:

  • Bio-inspired robotics
  • Hydrogel actuators
  • Smart materials

Background:

  • Living organisms adapt to environments via structure editing.
  • Replicating this natural capacity in artificial hydrogel actuators is challenging.
  • Existing hydrogel actuators lack life-like adaptability.

Purpose of the Study:

  • To create fluorescent hydrogel actuators with structure-editing capabilities.
  • To mimic the metamorphosis of glowing octopuses in artificial systems.
  • To develop a universal stepwise inside-out growth strategy for hydrogel actuators.

Main Methods:

  • Inspired by glowing octopus metamorphosis.
  • Developed a stepwise inside-out growth strategy.
  • Utilized environmental cues (temperature, pH) for actuation.

Main Results:

  • Constructed proof-of-concept fluorescent hydrogel actuators.
  • Actuators exhibit origami-like 3D shape deformation.
  • Actuators demonstrate postnatal growth of new structures for adaptive states.
  • Actuation and structural changes are triggered by environmental keys like temperature and pH.

Conclusions:

  • The study presents novel bio-inspired hydrogel actuators with life-like structure-editing capacity.
  • This approach enables adaptive actuating states for visual information delivery.
  • Opens new avenues in bio-inspired hydrogel actuators and robotics.
  • Extends potential applications in environment-interactive information encryption.
