The aim of this study is to develop a system to record small intestine myoelectric activity electroenterogram from abdominal surface. The difficult anatomic access is a technical problem for monitoring intestinal activity, therefore most methods are invasive. It results in many problems like the low amplitude of the signal recorded and physiological interferences captured. In order to avoid these troubles, and to estimate the location of the small intestine point whose activity is being recorded. it has been implemented a tripolar concentric ring electrode in bipolar configuration TCB. This electrode is based on laplacian theory. It was analyzed the signals recorded by TCB electrode and contrasted to the internal myoelectric signal and to the signals obtained from the body surface by using two unipolar electrodes.
