Created a robot moving like a sperm cell

British experts from Exeter University presented an innovative technology for moving a microscopic robot. To this end, a ferromagnetic head was placed on the basis of the device design.

In recent years, various methods of using mini-robots in the delivery of drugs to damaged tissues, as well as in minimally invasive operations, have been tested. It is likely that the experts have not yet found an ideal and safe mini-structure motion scheme, so most projects stop their work at the level of test trials.

The new invention of experts from the UK consists of a ferromagnetic head consisting of iron, boron, neodymium and a movable harness. Scientists were able to establish that by maintaining a certain frequency of the magnetic field and varying the length of the flagellum, it is possible to achieve a high degree of control by the robot, ensuring its movement in a clearly defined direction.

This scheme works great in nature. Many unicellulars move, causing the so-called turbulence of fluid flows next to them to cause the tail part of their body. By analogy, the robot will function.

The specific scope of the device is not yet announced, but it is most likely that specialists will try to introduce it into medical practice. The device can be used for drug delivery inside the human body, as well as for diagnostic procedures.
