RFID Helps Acid Reflux Sufferers
UT Southwestern Medical Center doctors and UT Arlington engineers have developed a wireless monitoring system that uses RFID to track esophageal reflux, reports UK tech pub Wireless Healthcare.
The new system involves pinning a small, flexible RFID chip to the esophagus, where it remains until removed by a physician.
The chip, about two square centimeters, or a little bigger than a dime, tests for electrical impulses that signal acidic or nonacidic liquids moving through the esophagus. It then transmits data to a wireless sensor worn around the neck.
The device, presented May 23 at the Digestive Disease Week conference in Washington D.C., is still in the test phase. ![[end]](/resources/bullet/rfidnews-4.gif)
