A 32 channel wireless system for recording gastric electrical activity
This paper presents a wireless system designed to collect, store and transmit gastric electrical activity, known as slow waves. The system is composed of a miniaturized front end module that can record from up to 32 locations of the stomach, and a back end module. The front end could either store the recorded slow waves into a flash memory, or wirelessly transmit them to the back end connected to a computer featuring a custom made graphical user interface (GUI) The GUI displays signals in real time, and stores them for off line analysis. The front end with the dimensions of 12x48x4 mm3, allows for potential implantation through laparoscopic or endoscopic procedure. The system was successfully tested on rigorous bench top experiments. The results of these tests showed that the system could run as designed and accurately map the signals collected by each sensor, as well as show that the flash memory could store data for almost 34 hours should wireless communication be lost.
