PHILLIPS: Now, imagine taking a pill that knows where to go in your body to deliver the dosage. Well, medicine and machine merge in the new iPill. Sean Callebs takes a look at how this smart pill works in today's "Edge of Discovery."</s>SEAN CALLEBS, CNN CORRESPONDENT (voice-over): Wireless technology is everywhere. And soon, it could even be inside us. Sound hard to swallow? Well, meet the iPill.</s>JEFF SHIMIZU, PHILIPS RESEARCH: What we're doing is we're putting smarts on board of a drug delivery pill.</s>CALLEBS: Part medicine, part machine. The iPill is equipped with microsensors and GPS-like navigation so it knows exactly where it is in the body. When it's time to deliver the dose, it goes to where your body needs it most. According to researchers, this makes the medication work better and limits potential side effects.</s>SHIMIZU: Medications today are basically designed for the average person. Some people it helps, some people it does no effect, and some people it makes sick. But if you can change that for the person, then you can widen that range of people who are going to be effectively treated by your medication.</s>CALLEBS: iPill is still being tested on animals, but it could be instrumental in fighting Crohn's disease, colitis and even intestinal cancer. And down the road, the small mechanics on this revolutionary pill could have an even larger effect.</s>SHIMIZU: This falls along the line with -- what's coming in the future is personalization of health care. We're programming that pill for you, and we're seeing if you're responding and changing as time goes on, rather than just sending you off with a bottle of pills and call me back in two months.</s>CALLEBS: Sean Callebs, CNN.
