Researchers believe that ingestible capsules have the potential to revolutionise the prevention and diagnosis of gut disorders and diseases.

An team has successfully completed phase one of ingestible smart capsules (the size of a vitamin pill) that journey through and measure gas levels in the gastrointestinal tract.

One in five people will suffer from a gastrointestinal disorder in their lifetime, with 30% of patients remaining undiagnosed. RMIT is one of the leading universities in the world researching the development of ingestible sensors.

The ingestible technology has demonstrated several thousand times more sensitivity to gut gases than alternative techniques.

Team lead and co-inventor said, 鈥淐urrently, one of the only methods for diagnosing gut disorders, such as malabsorption of carbohydrates, irritable bowel syndrome and inflammable bowel disease, is to measure hydrogen concentrations in the breath.

鈥淗辞飞别惫别谤, are mired by a lack of sensitivity and specificity and are unable to provide the necessary gold standard for diagnosis,鈥� he said.

Co-inventor Dr Kyle Berean said, 鈥淚ngestible sensors also offer a reliable diagnostic tool for colon cancer, meaning that people won鈥檛 have to undergo colonoscopies in future.鈥�

One unique feature of such ingestible sensors is that their passage through the gut lumen gives them access to each individual organ of the gastrointestinal tract.

鈥淪mart pills are harmless and there is no risk of capsule retention,鈥� Berean said.

An added advantage is that the capsules can be synched with smartphones, meaning results are easily accessible by users and doctors online.

The potential applications from this technology are profound.

鈥淭he sensors allow us to measure all the fluids and gases in the gut giving us a multidimensional picture of the human body,鈥� Kalantar-zadeh said. 鈥淕as sensing is just the beginning.鈥�
