While the idea of mini-robots hovering inside the human body was seen as a fictional act, all indicates that in a few years it could be a repetitive process, depending on the researchers. Vanderbilt UniversityIn Tennessee.
They recently released their “Milirobot“, A millimeter-long robot that operates by remote control and has the ability to climb inside the human body, especially for the use of drugs and even sensors.
In its previous version, the human body had difficulty moving due to its internal surface and non-adherence to fluids, so any sudden movement removes it. This has been solved in its new version, which now has small pads filled with needles to stick to the mucus and does not come out easily during respiratory or digestive movements.
The second Matin CityOf Max Planck Institute Positive results from Intelligent Systems, in Germany Milirobot Register “An important milestone in light robotics“
An important advance for treatment
O Milirobot It is made of ultra-thin, flexible magnetic metal, 3.7 mm long and 1.5 mm wide, and can carry up to three times its own size and up to 20 times its own weight, the research co-authors said. Yingdan Wu.
To control it, researchers need to use a machine that modifies the electromagnetic field around the organ, which Milirobot Rotate, that is, when one leg is on the ground, the robot pulls the other leg off the surface and rotates the body to take a “step” inside the body.

About the barrier of making it so that the mucous membranes can be attached and loosened, it was too long. According to the research co-author, Xiaoguang Dong From Vanderbilt University in Tennessee:
Inspired by the way some intestinal parasites attach themselves, the team first tried to attach pads to the tissue-catching claws. But they had difficulty reproducing the superpowers they needed – and it was difficult to free the robot. “
The solution discovered by a team of researchers is something that we Brazilians, who have at least been out of the house, know very well.
To mimic the same sticking and releasing effect, the “pillows” of the needles were covered with a thin layer of chitosan from the crustaceans’ crustaceans, which gave extremely positive results during the tests, as it now produces friction and stickiness. Enough to hold a layer of mucus in the lungs and digestive tract of pigs.
During the various tests performed in the laboratory, the team was very curious about their results. Such as Milirobot It only attaches to the mucous membranes, so there is no damage to the internal tissues and this makes it possible to use it for a variety of treatments or to take ingredients in organs like the heart.
You can’t deny the idea that in the future, we may have a lot of people with little robots who will have to deal with the most diverse diseases.
