'Smart underwear' measures how often humans fart

Everybody farts. The question is how often? And how much gas is too much gas to pass?
Those are questions that arose from frustration with a piece of lab equipment.

Microbiologist Brantley Hall of the University of Maryland in College Park and colleagues study the metabolism of gut microbes. They tried unsuccessfully to measure hydrogen production from gut microbes with a sensor in an oxygen-free chamber. Frustrated, “we took the sensor out of the chamber, and we were like, ‘Screw it. We’re going to try to measure a fart.’” So Hall stuck the device down his own pants and let rip. “And the signal was enormous.”
Inspired by that incident, the team devised “smart underwear” that can track toots, specifically the hydrogen part of farts. Hall and colleagues described their device — a small hydrogen sensor about as big around as a quarter that snaps to people’s regular underwear — in the December 2025 Biosensors and Bioelectronics: X.
In a test of the device, healthy college-age volunteers who wore sensors farted an average of 32 times a day. But that figure varied from a minimum of four flatus daily to a maximum of 59. Eating high fiber gumdrops caused 36 of 38 participants to break wind more often, the researchers found.

with the stench from just one gassy blast.
But I like Fartbit also! 
And DU ALWAYS comes thru!
Thank yous guys, for changing the energy before bed. It REALLY helps.
