Stanford University Researchers Develop Fantastic Voyage Chip

It echoes the Fantastic Voyage.  A tiny microchip that can potentially 'swim' through the bloodstream of your body has been developed by Stanford University researchers.

Stanford electrical engineers have created a tiny wireless chip, driven by magnetic currents, that's small enough to travel inside the human body. They hope it will someday be used for a wide range of biomedical applications, from delivering drugs to cleaning arteries.
