Medical Device Flows Through Blood Vessels

by / February 28, 2012

At last week's International Solid-State Circuits Conference, Stanford Engineer Ada Poon demonstrated a medical device that patients can swallow. This tiny, wirelessly powered, self-propelled device is capable of controlled motion through a fluid – blood, to be exact. And it's small enough to travel through blood vessels, Stanford University news reported

Shown above is the current prototype chip resting on a hand; it is only three millimeters wide and four millimeters long.
