Abstract

AM-In order to research gastric motility information, a new collection system base on ADuC834 was designed. ADuC834 was selected to collect the low-frequency gastric impedance signal. The filter circuit was simple and only got rid of the interference of EMG and ECG. The software base on wavelet transform assumed all signals processing work. The gastric motility information can be observed in this study. We can research gastric motility situation according to the signal extracted by ADuC834 and wavelet transform. ADuC834 is suitable for extracting the low frequency gastric impedance signal and can further simplify the hardware configuration. All useful gastric motility information can pass through the simple filter circuit. Wavelet transform have good performance to get rid of the interference. Experiments have proved that the system base on ADuC834 is feasible and a reliable collection system is provided to research gastric motility information.
