No More Blaming the Dog
[ArsTechnica] Scientists often hope to break ground with their research. But a group of Australian researchers would likely be happy with breaking wind.The Fart Tracker The team developed an ingestible electronic capsule to monitor gas levels in the human gut. When it’s paired with a pocket-sized receiver and a mobile phone app, the pill reports tail-wind conditions in real time as it passes from the stomach to the colon. The researchers, led by Kourosh Kalantar-Zadeh of RMIT University and Peter Gibson of Monash University, reported their invention Monday in Nature Electronics. Fart=Frequency Actuated Rectal Tremor  The authors are optimistic that the capsule’s gas readings can help clear the air over the inner workings of our intricate innards and the multitudes of microbes they contain. Such fume data could clarify the conditions of each section of the gut, what microbes are up to, and which foods may cause problems in the system. Until now, collecting such data has been a challenge. Methods to bottle it involved cumbersome and invasive tubing and inconvenient whole-body calorimetry. Popping the electronic pill is a breeze in comparison. And early human trials have already hinted that the pill can provide new information about intestinal wind patterns and gaseous turbulence from different foods. The biggest producer of VOC's (Volatile Organic Chemicals) in the workplace are Human Bioefluent Emmisions, burps and farts. "Our pilot trial illustrated the significant potential role for electronic-based gas-sensing capsules in understanding functional aspects of the intestine and its microbiota in health and in response to dietary changes," the researchers concluded. Advance warning of a hazardous vapor release. The authors are currently setting up a commercial company to further develop and test the capsules. For their pilot study, the researchers beefed up a prototype they had previously tested in pigs. The capsule is 26mm in length, with a 9.8mm external diameter‐like a large vitamin. Its polymer shell surrounds sensors for temperature, CO2, H2, and O2, as well as a button-size silver oxide battery and a transmission system. One end of the capsule contains a gas-permeable membrane that allows for fast diffusion of gut gases. Posted by: Deacon Blues 2018-01-11 |
