STANFORD (CBS13) - In the 1966 film "Fantastic Voyage," a submarine full of scientists is shrunk to microscopic size and injected into the bloodstream of a seriously wounded diplomat.
Forty-six years later, the idea sounds less far fetched. In a Stanford lab, engineers are perfecting their fantastic voyage.
Electrical engineer Professor Ada Poon, Ph.D.Poon says smaller is the name of the game.
"We have been in this project for more than four years. So we encounter a lot of obstacles along the way and then we solve them one by one, said Poon.
Instead of a battery, which takes up lots of space, the device that will be used for travel is powered wirelessly with electromagnetic radio waves.
"The prototype we built is 3mm by 4mm. You can see here that we have a 2mm by 2mm receiving antennae," said Dan Pivonka, PhD.
The result is a new class of medical devices that are so small they can travel through the bloodstream.
