Research progress of capsule system for alimentary tract physiological parameters testing in the alimentary tract

The physiological parameters within the alimentary tract is an important parameter which is used to diagnose alimentary motility disorders.Conventional catheter-based monitoring systems are uncomfortable and interfere with the normal activity of the patient.To overcome these disadvantages,a new type of capsule containing sensor for physiological parameters monitoring is presented,which is based on differences in physiological parameters to diagnose alimentary tract disease.International research achievement and domestic research at present of the capsule system for physiological parameters monitoring is presented.
