'Smart' Underwear Tracks Gut Bacteria By Measuring Flatulence (studyfinds.org)

Scientists have created a wearable sensor that attaches to your underwear and tracks your gut bacteria in real time by measuring the hydrogen gas in your flatulence. And no, that’s not a setup for a joke.

Researchers at the University of Maryland developed the device to solve a problem that has plagued microbiome research for years: how to actually monitor what gut bacteria are doing hour by hour, not just which species are living in there. The answer, it turns out, involves a tiny sensor clipped near your bottom that passively records data while you go about your day.

Sounds interesting and entirely unaffordable.

Sensors that track gasses are incredibly cheap. I can build a VOC, CO2, PM2-10, CO, Smoke, etc for about $50 from parts on AliExpress. A sensor that tracks just hydrogen should be way less.

Edit: ~~methane~~ Hydrogen

It might be cheap to build yourself then but cheap parts have rarely deterred a capitalist.
