Although robotics has long been unknown in healthcare (it’s enough to think about their surgical application), there is still plenty of room for new ideas on the subject. One of these was a team of researchers from the Chinese University of Hong Kong (CUHK). Scientists have such a complex deformation, flexible tool they workwhich they hope will be able to deal with a range of health problems easily and safely.
The structure, most similar to a single pile of mud, has a myriad of special abilities. On the one hand, it is able to show the characteristics of a non-Newtonian liquid, i.e., a solid and a liquid state, at the same time. A slime robot that can change its shape with an astonishment similar to the one known in the tale Pom Pom can squeeze itself through gaps of up to 1.5 millimeters, be able to enclose or “grab” objects, and self-healing is no stranger to it.
According to researcher Li Zhang, one of the project’s leaders, the reconfigurable magnetic slimy robot is soft and flexible enough to neutralize dangerous foreign objects, such as accidentally swallowed, by “encircling” the inappropriate element when inserted into the human body.
The robot is controlled by tiny magnetic particles mixed into the fluid, which allow the mucus to be manipulated with a magnetic field. It can be guided through tight spaces and channels with a single magnet, or fixed and stretched with two magnets. Rotating the control magnet creates an effect called an “octopus”, meaning that the mucus rolls up and is able to grab an object.
Because the mucus mixture can conduct electricity, the device can also be used to wrap wires in hard-to-reach places to repair circuits.
