The gel is similar in structure to muscle tissue due to its softness, 70% water content and the ability to respond to electrical stimulation.
Researchers from the University of Rutgers, New Brunswick, created a material that can be described as "smart gel." Figures from this gel, printed on a special three-dimensional printer, are able to walk independently under water and even move small objects. The appearance of such material can lead to the creation of a new type of soft robots, imitating some marine living creatures, such as squid and octopus, capable of capturing and moving various objects without causing them physical damage. In addition, the new material can become the basis of artificial muscles that activate artificial organs, such as the heart.
"Our clever gel will find a lot of applications, especially in bioengineering, because it is similar in many respects to the tissues of living organisms, like living tissues, it is very soft and contains a lot of water," says Howon Lee, , one of the researchers, "The material can become the basis for new types of underwater devices that will resemble some marine life, such as octopuses, for example."
To produce a clever gel, a special photosensitive solution is used, which under the influence of light turns into a denser substance. After that, objects from the gel are placed in salted water, where two electrodes are also lowered. The combination of salt concentration in water, polarity and strength of the created electric field allows to control the shape and movements of the object from the gel.

In the above video, you can see various options for using a new clever gel, and the most amusing version is an inch figure of a little man who is able to step underwater under the influence of a pulsed electric field.
