ABSTRACT
Many diseases of gastrointestinal tract have close relation to the changes in gastrointestinal (GI) motility. Making use of the technique of MEMS, we developed a micro-interposed system to monitor the motility and pH value of the whole GI tract under normal physical state. This paper focuses on an automatic analysis of the acquired signal to draw conclusions for aiding diagnosis of diseases. The techniques of smoothing signal, removing singular value, feature extraction and selection as well as classification of normal and abnormal samples are discussed in details. These techniques provide a comprehensive method for analyzing long-term motility recordings which will complete the function of the in vivo monitoring system and serve for medical applications.
