Summary

Story summary

U.S. researchers created smart underwear that continuously measures flatulence with electrochemical sensors.
Brantley Hall of the University of Maryland leads the device’s development and the Human Flatus Atlas.
The disc snaps into underwear and detects hydrogen to estimate gas production.
Over 500 volunteers wore the device up to 30 days, monitoring 22-hour daily use.
Researchers hope objective fart data will help diagnose gastrointestinal conditions and improve high-fiber diet tolerance.
