A study done by Julia et al. proved the possibility of using multi-material direct ink printing (4D printing) technology to integrate magnetic nanoparticles with hydrogels. The contactless in-air control of motions like rolling, jumping, and bending is realised because of the interactions between magnetic and nonmagnetic hydrogels. The programmability of patterns of the multi-material also enables its future potential in soft robotics

Another fantastic work of 3D printed responsive hydrogels by Dr Ali Mohammed!
The superparamagnetic starfish-shaped hydrogel can be used for magnetically simulated soft robotics and actuators.
Check out the videos to see the 3D printed ‘starfish’ moving responsively to the magnet:
