| Abstract Scope |
In this study, we explore a novel, self-healing hydrogel system engineered to support magnetic soft robotics, manufactured using Direct Ink Writing (DIW) 3D printing. The hydrogel comprises an interpenetrating polymer network (IPN) of poly(vinyl alcohol), poly(acrylic acid), and ferric chloride, where physical and ionic cross-linking enable rapid self-healing without external stimuli. Fe3O₄ magnetic nanoparticles were incorporated into the hydrogel, allowing for remote actuation through external magnetic fields. By magnetizing individual hydrogel segments with a defined field direction and then healing them together, soft actuators whose motion is remotely controlled can be built. This work proposes an effective, sustainable solution for creating remotely controlled, self-healing soft robots, with potential applications in areas such as medical devices. |
