Our recent work was recently published on Matter with title “Synergistic Photoactuation of Bilayered Spiropyran Hydrogels for Predictable Origami-like Shape Change”. Check details on Matter website.


  • Bilayer hydrogels exhibit opposite volumetric change in response to light exposure
  • Coupling expanding and contracting layers generates synergistic bending with light
  • Constructs exhibit light-driven locomotion and origami-like 3D shape changes
  • Observed shape changes in designed constructs predicted by analytical modeling
