The study will enroll a maximum of 500 adults across the United States who will wear the device for three consecutive days while continuing their usual daily activities.\n\nThe main questions it aims to answer are:\n\n* What is the average frequency of flatus events in a general adult population?\n* How does dietary fiber intake influence flatus frequency and microbiome activity?\n\nResearchers will collect gas sensor data from the Smart Underwear device alongside dietary information logged in a mobile app to assess the relationship between diet and microbiome activity.\n\nParticipants will:\n\n* Complete an online eligibility survey, consent form, and background questionnaire.\n* Wear the Smart Underwear device for at least 12 hours per day for three consecutive days.\n* Log all meals with photos using a custom smartphone app.\n* Complete a short post-wear survey about device comfort and usability.\n\nAll study procedures will be conducted remotely. Data will be analyzed in de-identified form to evaluate baseline flatulence patterns, normalized to fiber intake, in the general adult population.",[63],"All Health Backgrounds to Determine a Baseline of Flatus Activity","2025-12-19",{"date":66,"type":67},"2025-12-23","ACTUAL",{"date":69,"type":67},"2025-12-01",{"date":71,"type":59},"2026-12-01",{"name":5,"class":6},2]
