Israeli millimeter robot can enter the blood vessels

Israeli scientists say they have created the world's smallest robot , which is 1 mm in diameter and 4 mm long and can enter human blood vessels and send drugs to the body.

This type of robot is "crawling" rather than "swim" when moving in a blood vessel, which also makes it easier to control its movement in the blood vessels. The robot has a robot that grips the inner wall of the blood vessel so that it can withstand the impact of blood flow and keep moving forward.

The robot itself does not carry a battery, and its power is derived from the vibration excited by an external magnetic field. Because all of its energy comes from the outside, this robot can not only work in the human body without time under human control, but also allows the scientist to minimize the size of the robot. The researchers said that in minimally invasive surgery and in the treatment of cancer, the robot can be used as a Tool for delivering drugs to solve the problem of how to accurately apply the drug to the site of treatment.
