A team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours—essentially an electrocardiogram but for the gastro-intestinal (GI) tract.
Applications include monitoring GI activity for patients outside of a clinical setting, which cuts down costs. Monitoring for longer periods of time also increases the likelihood of capturing abnormal events.
Researchers detail their findings in the March 22 issue of Nature’s open access journal Scientific Reports.
The team tested the device, a 3D printed portable box connected to 10 small wearable electrodes, on 11 children and one adult volunteer. They found that data collected with the wearable system were comparable to data collected in the clinic with state-of-the-art methods, which are invasive--including a catheter inserted through the patient’s nose. They also found that the stomach’s electrical activity changes not only around meals, but also during sleep, following its own circadian rhythm.

The system also comes with an app that allows patients to log their meals, sleep and other activities. (Credit: University of California San Diego)
