Physical model of the stomach motor activity

In this work a stomach motor activity physical model is described. An electromechanical prototype and a personal computer are used. The measured parameters are: pressure, pH, system temperature and the velocity of the bolus. The system uses a personal computer for acquiring, processing and storing the results. On the other hand, the PC sends digital signal to the system for the prototype control. The results obtained allow one to reproduce an approximation of the motor behavior of the stomach.
