Electrical bio-impedance method to measure gastric motility function / 国际生物医学工程杂志

ABSTRACT

During the digest course the electrical property of the stomach alters obviously due to the change in shape, dimension, volume of gastric and the composition of stomach. The regulation of the impedance change is corresponding to the gastric motility and the correlation between them is evident. The impedance technique can be used to monitor gastric motility function no-invasively with high sensitivity and accuracy. Based on introduction of the gastric motility function and its measurement method, the development, key technique and existing problem of the gastric motility measurement using the electrical bio-impedance method are reviewed in this paper.
