Wearable fart tracker aims to map digestion and gut health
A disc-shaped sensor snaps into the back of underwear to measure hydrogen in farts, forming part of the Human Flatus Atlas. It lets wearers go about their day while researchers study how gut microbes respond to diet and how fiber influences gas production, with the goal of improving digestive health. Early studies found an average of about 32 farts over roughly a week of wear; a later study with 500+ volunteers tracked 22 hours a day for 3 to 30 days. The device is not medical-grade yet, but scientists hope it could help diagnose or monitor GI conditions and inform personalized dietary or microbiome-focused therapies. Still, fart frequency alone isn’t a diagnostic tool.
