摘　　要：介绍一种用于经络三维定位的多通道经络阻抗检测仪。根据经络的低阻抗特性,采用四电极法进行多通道经络阻抗检测仪各模块的设计,包括信号发生器、压控电流源、隔离放大电路、幅度检测电路、A/D数据采集模块和PC机数据处理模块等。根据多个中低阻通道的位置确定经络的位置,并通过实验验证经络的三维定位的准确性。This paper introduces a multi-channel meridian impedance detector applied tbr 3D meridian positioning. Designed by the four-electrode method considering low impedance of the meridian, this detector consists of some modules including a signal generator, a voltage-controlled current source, isolation amplifiers, amplitude detectors, A/D acquisitions, and some data processing modules. Then with application of this new device, meridian position is determined with multiple medium and low resistance channels, 3D positioning accuracy has been verified by experiments.
