Talk about taking the red pill! If you really want to know what's going on in the world of your digestive tract, the pill-size camera will take you to Zion. Pill cameras have been out for a while, but doctors plan to use a new image sensor developed by South Korean semiconductor manufacturer MagnaChip to get up-to-the-minute information about what's troubling patients down below. The MagnaChip sensor is specifically developed to handle the romantically low-lit atmosphere of your intestines. This tiny disposable Gilligan can take up to 50,000 photos on its eight-hour tour through your innards, and report back wirelessly to a hard drive worn on your belt (which doubles as a fashion accessory, to boot).
