“…The construction of the Hele‐Shaw cell system is similar to that presented by Walton and co‐workers, [ 42,43 ] where spacing materials (e.g., plastic shims with thickness range 0.025–3 mm) were used as spacers to control the gap height. First, the pre‐gel of the nonfunctional hydrogel substrate—a fine volume controlled low‐swelling hydrogel—was micropipetted within the hydrophilic zone of the bottom plate surface.…”

A unique microfluidics approach for functional hydrogel patterning with multilayered heterogeneous structures is presented. Prepolymer solution droplets with differentiated sodium acrylate concentrations are dispensed/printed in a wetting‐controlled “two‐parallel plate” (TPP, like a Hele‐Shaw Cell) system. The gelation within the system enables hydrogel bilayer structures with reconfigurable 3D deformations driven by in‐plane and through‐thickness heterogeneity under stimuli‐responsive mask‐less swelling/deswelling. The cooperation between swelling mismatch of functional groups results in a higher complexity of 3D reconfiguration in responding to discrete levels of stimulation inputs. This facile patterning technology with an in‐built ionic hierarchy can be scaled up/down with advanced transducing functionalities in various fields.
