Necklace could help patients take their medication on time

Chicago Tribune, May 20, 2008
Engineers at Georgia Institute of Technology are developing a sensor-equipped necklace to help patients take their medication on time. "MagneTrace" uses magnetic sensors embedded in pills to detect when a pill is ingested. The sensors pass through the patient's digestive system. If a pill is not taken at the correct time, the necklace sends a signal to a smart phone that alerts the patient. If that prompt is ignored, the phone contacts a doctor or caregiver.
