Abstract
We study swelling-induced bending of hydrogel bistrips comprising an elastomer strip and a gel strip by using finite element method. The constitutive laws of the elastomer and gel strips are assumed to be the neo-Hookean and Flory–Rehner models, respectively. We explore the swelling-induced bending of bistrips due to chemical potential and specifically focus on how the stiffness and thickness ratios between the elastomer and gel strips affect their swelling-equilibrium shapes. We show that there exist the specific values to maximize their bending curvatures.
