University of Florida scientists have developed a new gadget that basically annoys patients into taking their prescribed drugs, then tests their breath to ensure that they've actually swallowed the necessary pill. When it's time to take your medication, the machine beeps. Ignore it and it beeps again. In fact, it gets louder and louder until you actually respond--after a predetermined time, if you haven't swallowed your meds, it sends a message to the clinical trial coordinator. The device also performs a breath test that picks up the presence of a chemical tracer.
