Medical Robots As Small As Bacteria
April 21st, 2009

Swiss scientists from the Federal Institute of Technology in Zurich have developed some tiny corkscrew shaped robots that can swim through liquids. They are so tiny that they could be used to repair a humans arteries. It’s about one half the width of a human hair.
The robot is made up of one part nickel, allowing it to move up to a speed of 20 micrometres per second in a low magnetic field. By manipulating the magnetic field, the robot can be steered to go where they want it.
