ABSTRACT
Bioelectrical Impendance Measuring Technology(BIMT)is a new technology developed in recent years. Due to the feature of non-invasive, low-cost, safety, and easy handle, it has the widespread application prospect and the scientific research value. It has aroused great attention of scholars at home and abroad, especially in the field of Biomedical Engineering and Clinical Medical Engineering.
This paper firstly introduces some techniques of impedance measurement and virtual instrument which will become the development trend. It is also established that framework of virtual instrument, LabVIEW and main function module. Then, the paper presents the priciples of impedance measurement. In addition, the paper also describes how to use the ActiveX technology in the LabVIEW programming some details was given about Labview programming.
