Electrogastrography (EGG)

Purpose-built sensor for gastric activity measurement.

The biosignalsplux Electrogastrography (EGG) sensor has been designed for user-friendly recording of the electrical activity of the stomach. Multiple sensors can be used simultaneously in a cost-effective and straightforward way to assess bowel motility and overall gastric activity, for instance.

The bipolar configuration, with two measurement electrodes, detects the electrical potentials in the specific stomach region of choice, with respect to a reference electrode (placed in an area of low bioelectrical activity). The resulting signal is the amplified difference between these two leads, eliminating the common unwanted signals. Its convenient form-factor enables a discrete application in the typical EGG.
