Schematic illustration of multi‐stimuli‐responsive soft robots (MSRs). MSRs have hydrogel (xerogel), elastomer (PDMS) and magnetic nanoparticle (MNP) composite sandwiched structures that enable shape morphing and locomotion in response to up to six stimuli: humidity, temperature, light, radio frequency (RF) heating, low‐frequency magnetic fields, and chemical solvents.
