摘　　要：针对血栓弹力图仪(Thrombelastography,TEG)的测量原理,提出一种能精确测量的基于非接触式电磁感应的角度传感器,最大程度减小了对被测量血液特性的影响。描述了测量原理,给出了相应的电路以及上位机软件,搭建了血栓弹力图仪的测量装置。实验结果表明:本传感器完全能满足血栓弹力仪的要求。This paper proposed an accurately angle sensor according to the principle of Thrombelastography （TEG）, which based on the non-contact electromagnetic induction principle and minimized the influence of the characteristics of blood. This paper described the measuring principle in detail, and expounded the corresponding circuit design and software of the system, and built measuring device. The experimental results show that this sensor has fully reached the requirements of thrombelastography.
