DALLAS — May 29, 2007 — UT Southwestern Medical Center doctors and UT Arlington engineers have developed a wireless monitoring system that uses electrical impulses to track esophageal reflux.The wireless technology, called radio frequency identification (RFID), has been used in thousands of stores for tracking inventory and in identification chips implanted in some pets. Researchers combined that technology with another emerging applied science called impedance monitoring, which tracks reflux through electrical impulses.
