Novel 3D Printed Wearable Device Monitors Metabolic Activities in Stomach
The device is described as an electrocardiogram for the gastro-intestinal (GI) tract. It is intended to monitor electrical activity in the stomach for 24 hours
Researchers from the University of California at Berkeley and the University of California at San Diego in collaboration developed 3D printed wearable device to monitor stomach. It comprises 3D printed portable box, which is connected to 10 wearable electrodes that fit on abdomen of an individual over the stomach. The system is synchronized with an app that allows patients to log activities such as meals and sleep.
As a part of the study, team examined effect of the device on 11 children and one adult volunteer. Results of the examination showed that data collected on the system was comparable to invasive clinical data. Also, it reported that stomach’s electrical activity changes around meals and also sleep, following specific circadian rhythm. This device has applications in monitoring GI activity for patients outside of a clinical setting. It can also detect abnormal events in daily metabolism of an individual. Furthermore, researchers are working on developing an app that collects data in real-time for patients and physicians, which can be used in diagnosis and treatment of various metabolic disorders.
Cardiac electrical signals are weaker as compared to stomach signals. The team developed an algorithmic pipeline to clean up the data and separate out abdominal muscle activity, heart beats and gastric activity. The device can be effectively used to improve the management of patients with diabetes and Parkinson’s, as GI problems such as delayed emptying of the stomach are common symptoms of these diseases. Moreover, it can be used to monitor the GI activity of athletes and pregnant women suffering from heartburn and other issues.
