Robot Crawls Through Veins to Kill Heal You
“A new robot, just one millimeter in diameter, can crawl through your veins to treat arterial blockage or deliver targeted medication. Developed by researchers from Israel’s Technion University, what makes the robot feasible is that it isn’t self-propelled, saving size and engineering complication. Instead, the bot takes advantage of a magnetic field from outside the body, meaning that doctors can not only guide but also propel the the vein crawler forward at 9mm/second. And the robot shouldn’t run out of power mid-procedure, stalling it in your body as it drifts for your brain.”
