Scientists at the University of Maryland have created Smart Underwear, the first wearable device designed to measure human flatulence. By tracking hydrogen in flatus, the device helps scientists revisit long-standing assumptions about how often people actually fart. It also opens a new window into measuring gut microbial metabolism in everyday life.

For decades, physicians have struggled to help patients with intestinal gas complaints. As gastroenterologist Michael Levitt, known in the field as the “King of Farts,” wrote in 2000: “It is virtually impossible for the physician to objectively document the existence of excessive gas using currently available tests.”
