Study on a method of measuring bioeletromagnetic field

Nowadays, the bioelectromagnetic field has been accepted, and more and more scientists are concerned about the bioelectromagnetic effect from external electromagnetic field. But few scientists study the bioelectromagnetic spectrum, which features may be used to identify the living beings. In this paper, we give a method to measure the bioelectromagnetic field. At first, we study the theory of measuring the bioelectromagnetic signal. Furthermore, we designed an automatic test system (ATS) based on the theory. The automatic test software, an important part of the ATS, which can control the instruments such as spectrum analyzer, poisoning controllers, etc, is introduced by the diagram. Finally, the measurement data are calculated and recorded to a text file, which can be used to analyze the bioelectro-magnetic spectrum. We also display the 3D graph of the bioelec-tromagnetic field vs. each frequency, to study and view the direction of bioelectromagnetic field. The automatic system has been applied in our research about mice´s bioelectromegnetic field test, and works well.
