The team is constructing the Human Flatus Atlas, bringing modern wearable monitors to bear on digestive health, measuring the frequency and intensity of farts. The team even had to create an artificial butt that could pass gas on command while developing the prototype. According to the Wall Street Journal:
In the current study, the Human Flatus Atlas app asks participants to take a picture of everything they eat and drink. Researchers could analyze that data, seeking correlations between diet and the sensor’s main metric: the total volume of gas passed in a day.
