Sounds creepy right? But it’s actually a new way to help acid reflux sufferers. UT Southwestern Medical Center doctors and UT Arlington engineers have developed an RFID chip which tests for electrical impulses that signal acidic or nonacidic liquids moving through your esophagus. The data is then transmitted to a wireless sensor worn around the neck. This system is still in it’s test phase, no word on when it will be fully launched. Via RFID News
