A Wearable System to Continuously Monitor Gastric Myoelectric Activity

awearablesys

A team comprised of researchers and doctors (from UCSD Department of Bioengineering, UCSD Department of Pediatrics, UCSD Department of Psychology, UC Berkeley GI Motility & Physiology Program, and Neurogastroenterology and Motility Center, Rady Children’s Hospital at San Diego) published an article online, dated March 22, 2018, in Nature.

Non-invasively, gastric bioelectrical data was obtained and processed using an modified OpenBCI Cyton 8-channel board with OpenBCI Snap Cable electrodes. The team programmed an algorithm to amplify and process the data, thus eliminating ambulatory noise and separating signals. Once cleaned, the data is sent to a phone app using a communication chip on the board.

Their work was featured in many articles, a few of which are linked below.
