While schools in the ACC are certainly making noise on the hardwood, it seems that the Atlantic Coast Conference is also interested in shoving microbots all around your innards. Just days after a team from Georgia Tech envisioned a new internal method for monitoring blood pressure, research conducted at NC State is hoping to cram even more robotic creatures into deep, dark places within your body. A team led by Orlin Velev has discovered that "a simple electronic diode" could spark a new form of propulsion which could power robots and other diminutive devices from a distance. By exploiting "a phenomenon known as electro-osmosis," the diodes can push microscopic material through internal fluids "at speeds of several millimeters per second," which could allow cameras and medicines to reach critical locales that are presently isolated. Of course, there's still a good bit of work to be done, as the prototype device still has become substantially smaller before it will even fit in most of the tiny tubes within your skin, but it's looking more and more like we'll have nursebots shoving spinoffs of themselves into our beings before too long.[Via NewScientistTech]
