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.
At DeviceTalks Boston, Tyler Shultz will give attendees an inside look at Theranos and how he was able to sound the alarm after he realized the company was falling apart. Shultz will take attendees behind the story that everyone is talking about: the rise and fall of Elizabeth Holmes and her diagnostic company, Theranos.
Join Shultz and 1,000+ medical device professionals at the 8th annual DeviceTalks Boston.
