摘　　要：医学电阻抗技术具有无创、廉价、功能信息丰富等优点。详细介绍了基于ADuC834的胃运动阻抗信号采集系统的硬件、软件设计。经验证该系统是可行的,能够实现胃运动阻抗信号的采集,不仅节约了成本,降低了功耗,而且仪器体积可进一步缩小,同时提高了整体性能和可靠性。Medical electrical impedance technology is an invasive and inexpensive method which provides rich information of function. In this paper, the hardware and software design of the collection system for the gastric impedance signal based on ADuC834 is introduced in detail. Experiments proved that this system is feasible, not only the system configuration can be simplified but also the dependability of the system can be improved, and at the same time the cost can be reduced.
