Ingestible Electronic Capsule Measures Gases in the Gut

摘要

The results of a pilot trial involving 6 healthy volunteers were recently published in Nature Electronics . Patterns of hydrogen and carbon dioxide, which are largely produced by food fermentation in the gut, corresponded with volunteers’ prescribed fiber consumption. Oxygen concentrations indicated when the capsule left the stomach and moved from the small intestine to the colon, which was confirmed with ultrasound.
