Three days with a fart-detecting wearable unlocks gut-health clues
A Gizmodo tester wears the University of Maryland’s Smart Underwear fart detector for three days, attaching a clip-on sensor to track hydrogen in farts and infer gut microbiome activity. The study aims to establish baselines for normal fart patterns, compare them against diet (including a planned low-FODMAP day), and contribute data to the Human Flatus Atlas. Findings from the test aligned with diary entries, showing variability in fart frequency and suggesting potential uses for personalized gut-health guidance and even cancer-prevention insights, with plans to scale up recruitment and commercialize the tech via Ventoscity LLC.
