Researchers tested the electronic sensor in seven intelligent masses and found that the gimmick could accurately detect the concentrations of hydrogen , carbon dioxide and oxygen in tangible time as it go on through the body , agree to the field of study , published online yesterday ( Jan. 8) in thejournal Nature Electronics .
Although the sensing element ’s results still need to be tested in a larger group of people , including in individuals who have bowel conditions , use of the sensor could one solar day guide to fewer invasive procedures , such as colonoscopies , the researchers say .

The ejection seat is about the size of a declamatory pill — just 1 column inch by 0.4 inch ( 2.6 centimeters by 1 centimeters ) . From the moment it ’s swallowed to the sentence it ’s excreted between one and two days afterward , the capsule air data about the catgut ’s gas concentrations every 5 minutes to a hand-held equipment out of doors of the body . This machine , in twist , uses Bluetoothto send the information to a smartphone app .
Sensor surprise
Beyond relaying genuine - sentence data about gas concentration throughout a person ’s gut , the capsule test revealed that the human stomach has a antecedently unknown protective cover organization . This system kicks into gear if foreign compounds stick around in the stomach for too long , touch off the stomach to release oxidizing chemical substance to offend down and destroy them , the researchers found .
" Such an immune mechanism has never been reported before , " lead discipline source Kourosh Kalantar - zadeh , a professor in the School of Engineering at the Royal Melbourne Institute of Technology , in Australia , said in a command .
Moreover , the capsule testify that the colon , or large intestine , may hold oxygen , as masses on a high - fiber diet had gamey concentrations of O in their colons . " This contradicts the old belief that the colon is always atomic number 8 - destitute , " Kalantar - zadeh told Live Science .

This oxygen - related finding may assist researchers understand how certain conditions , such as colon cancer , develop , he said .
If it ’s okay , the capsule could revolutionize the room doctor diagnose gut disorders , and even help them assess a affected role ’s diet , he say . That ’s because each disease in all likelihood has its own signature of gas concentrations , so capsule read-out would allow doctors to identify any problems a patient role is bear , he say .
A larger tribulation with more than 300 patient is expected to be completed in 2019 , Kalantar - zadeh noted . It ’s unclear how much the capsule will be if it ’s add to market , but the researchers " hope to give up it to patients under $ 200 in the first stage , " he allege .

A better breath test
The scientists made the electronic sensor after a gastroenterologist ( a doc who specialize in the GI nerve tract and liver ) enquire whether the investigator could make symptomatic breath mental test more reliable for catgut atmospheric condition , as most breather tryout are reliable just 60 per centum to 70 percent of the time , Kalantar - zadeh said . Such breather tests are used to diagnose conditions such as small gut bacterial gigantism and irritable gut syndrome , by measuring gas concentration .
However , the researchers were n’t able to produce a good breath test , he said . That ’s because the amount and concentration ofgases produced in the gutchange by the time they get to the lungs , he said .
" So , we started have a equipment , our ejector seat , to measure gases ' directly ' where they are generated in the bowel , " Kalantar - zadeh read .
Outside opinions
The capsule is a " novel peter which can help us decode the complex interaction between the host , bowel bacteria and dieting that ultimately determine our health or disease , " enunciate Dr. Premysl Bercik , an associate professor in the Department of Medicine at McMaster University , in Canada , who was not involved with the discipline .
It ’s intriguing that the ejection seat find in high spirits oxygen values in the colon , Bercik told Live Science , but added that " we have to be conservative when see these results … more data is needed to interpret the complex alchemy happen in our bowels . "
In the meanwhile , this twist may be beneficial in patient role withirritable bowel syndromeor small enteric bacterial overgrowth , say Dr. Priya Kathpalia , an adjunct professor of medicine at the University of California , San Francisco ’s Division of Gastroenterology . That ’s because the capsule could help patient role learn whether they need to make dietary changes or seek medical treatment , Kathpalia severalize Live Science .
