Ingestible sensors could be used to monitor gasses in the gastrointestinal system, including the effects of diet on individuals and as diagnostic tools for stomach contents and health, according to a new study.
Results from the study which explored the use of new ingestible sensors were published this month in the journal Nature Electronics.
In the human pilot trial, researchers tested an ingestible electronic sensor designed to detect and measure levels of oxygen, hydrogen and carbon dioxide using thermal conductivity and semiconducting sensors.
Research investigators said that gas profiles were successfully obtained while modulating gut microbial fermentative activities by altering intakes of dietary fiber using the experimental ingestible sensor.
Oxygen-equivalent concentration profiles produced by data from the ingestible sensors and confirmed by ultrasound imaging, according to the study results.
In a crossover study, variations of fiber intake were recorded as being associated with differing small intestinal and colonic transit times and gut fermentation, according to results. Regional fermentation patterns were also defined through hydrogen gas profiles.
Researchers reported that the capsule could accurately and safely be used for monitoring the effects of diets on individuals, and believe the tool could be used as a diagnostic device for stomach health.
