Abstract
A magnetically driven hopping soft robot based on magnetically programmed temperature-sensitive hydrogels includes first moving bodies and a second moving body. Several first moving bodies are distributed evenly on a bottom portion of the second moving body. The first moving bodies are made of a temperature-responsive hydrogel containing magnetic particles. An alternating magnetic field is applied to the first moving bodies to cause the first moving bodies to deform due to magnetocaloric effect. The first moving bodies have a two-layered structure. A first layer is made of a double-network cross-linked hydrogel and a second layer is made of a magnetic temperature-responsive hydrogel with added magnetic nanoparticles. An alternating magnetic field is applied to the first moving bodies in a manner that an amount of deformation of the second layer is greater than that of the first layer. The second layer is made of a temperature-responsive hydrogel with added magnetic nanoparticles.
