Water-Induced Shape-Locking Magnetic Robots.

ABSTRACT: Untethered magnetic soft robots capable of performing adaptive locomotion and shape reconfiguration open up possibilities for various applications owing to their flexibility. However, magnetic soft robots are typically composed of soft materials with fixed modulus, making them unable to exert or withstand substantial forces, which limits the exploration of their new functionalities. Here, water-induced, shape-locking magnetic robots with magnetically controlled shape change and water-induced shape-locking are introduced. The water-induced phase separation enables these robots to undergo a modulus transition from 1.78 MPa in the dry state to 410 MPa after hydration. Moreover, the body material's inherent self-healing property enables the direct assembly of morphing structures and magnetic s
