There’s a Microscale Robot on This Penny That Can Travel Through Your Body


Engineers are building tiny magnetic robots that could deliver medicine to an exact spot in your body. Here’s how they work.

Medicine of the Future: New Microchip Technology Could Be Used to Track Smart Pills
“Researchers at Caltech have developed a prototype miniature medical device that could ultimately be used in “smart pills” to diagnose and treat diseases. A key to the new technology—and what makes it unique among other microscale medical devices—is that its location can be precisely identified within the body, something that proved challenging before.”

All-terrain Microbot Moves By Tumbling Over Complex Topography
“The “microscale magnetic tumbling robot,” or μTUM (microTUM), is about 400 by 800 microns, or millionths of a meter, smaller than the head of a pin. A continuously rotating magnetic field propels the microbot in an end-over-end or sideways tumbling motion, which helps the microbot traverse uneven surfaces such as bumps and trenches, a difficult feat for other forms of motion.”

Why Swallowable Robots Could Be The Future Of Healthcare
“Almost any drug that a patient takes orally will have an effect across the body — sometimes that effect is wanted, often it’s not. If a microscale device could be used to make sure that the drug could be delivered to the problem area, and only that area, it could potentially drastically reduce unwanted side effects from pharmaceutical therapies.”
