A team of engineers from the Massachusetts Institute of Technology (MIT) in the United States has created a fine-threaded robot that can move within the arteries of the brain, and can be controlled by magnetic field techniques.
The researchers said the robot could be developed in the future and provided with therapeutic means to dissolve strokes and deal with tumors inside the brain.
Researcher Chan Zaw, a professor of mechanical and environmental engineering at the Massachusetts Institute of Technology, said the design of a device that helps remove the blockage inside the artery at this golden hour could avoid permanent brain damage.
The new robot's body is made of nickel-titanium, and the study team wrapped the robot's body from the outside with a rubber paste containing magnetic particles.
The researchers surrounded the body of the robot hydrogel, which does not affect its magnetic properties, and provide a high degree of fluidity and ease of movement within the human body.
