'Tattletale Pill' Reports When Patients Eat It

Researchers have invented a pill that goes far beyond the usual call of duty—it helps patients and loved ones keep track of when it's taken. The pill has a tiny microchip and antenna (both nontoxic and digestible) that sends a signal when consumed to a receiver worn by the patient. The receiver then signals a cell phone or laptop, which could be monitored by the patient's family or doctor. A prototype of the so-called tattletale pill is in development.

"It's a way to monitor whether you're taking your medication in a timely manner," a University of Florida professor involved in the project tells the Gainesville Sun. (More University of Florida stories.)
