Blueprint: A Mini Sub That Could Steer Through The Body


  • About the size of "Abraham Lincoln’s head on a penny," the device could travel through your body to deliver drugs and take samples.
  • It is powered wireless by sending radio waves to its two-by-two-millimeter antenna.
  • With the magnet, the prototype moves about 0.2 inches per second in a dish of saline.
  • If it were in the blood stream—cleaning out your arteries, for example—you'd need a stronger magnet to overcome the flow of blood.
