Microbots to treat stroke patients
According to a study published in the Journal of Micromechanics and Microengineering, the robots can circulate the body through the bloodstream even go against the blood flow to reach the troubled cranial artery.

The minuscule motors are designed to travel to the damaged cranial arteries and help surgeons treat stroke patients and those suffering from dangerous heart conditions.

The use of this wireless motor known as Proteus can improve the success rate of operation by helping surgeons act more quickly and with greater precision.

The 250-micrometer microbots have shown promising results when tested in human blood and artificial arteries; scientists, however, are optimistic that they will be able to power their way up the narrow arteries of the brain in human cases as well.
