Area of Science:

  • Materials Science
  • Polymer Science
  • Soft Robotics

Background:

  • Multi-layered hydrogels are utilized for soft hydrogel actuators via self-folding.
  • Precise control over self-folding curvature is essential but often challenging.
  • Existing methods struggle with undesired mismatches between designed and actual self-folding curvature.

Purpose of the Study:

  • To introduce and evaluate an interfacial diffusion layer for enhancing precision in multi-layered hydrogel actuators.
  • To investigate the impact of the interfacial layer on self-folding curvature and system robustness.
  • To develop a novel strategy for fabricating accurate and durable soft hydrogel actuators.

Main Methods:

  • Fabrication of multi-layered hydrogels with varying interfacial layer thicknesses.
  • Characterization of self-folding behavior and curvature changes.
  • Assessment of layer adhesion and system integrity during actuation.

Main Results:

  • The interfacial layer significantly reduces mismatch in self-folding curvature.
  • A 3.5-fold increase in the radius of curvature was observed with increasing interfacial layer thickness.
  • The interfacial layer prevents layer separation, ensuring system integrity during actuation.

Conclusions:

  • Incorporating an interfacial diffusion layer is a viable strategy to enhance the precision of multi-layered hydrogel actuators.
  • This approach improves the reliability and robustness of soft hydrogel actuators by maintaining layer adhesion.
  • The findings offer a new pathway for designing and fabricating highly precise and durable soft actuators.
