英文摘要	Shape morphing is a critical aptitude for the survival of organisms and is determined by anisotropic tissue composition and directional orientation of micro- and nanostructures within cell walls, resulting in different swelling behaviors. Recent efforts have dedicated to mimic the behaviors that nature has perfected over billions of years. We present an intriguing strategy for preparing 3D periodically patterned single-component sodium alginate hydrogel sheets crosslinked with Ca2+ ions, which can reversibly deform and retain into various desirable inside-out shapes as triggered by biocompatible ions (Na+ /Ca2+). By changing the orientations of the patterned microchannels or triggering with Na+ /Ca2+ ions, various 3D twisting, tubular and plant-inspired architectures can be facilely programmed. Not only can the transformation recover their initial shapes reversibly, but also can keep the designated shapes without continuous stimuli. These inside-out 3D reversible ion-triggered hydrogel transformation shall inspire more attractive applications in energy harvesting, biomedical devices, and soft robotics fields.
