血液在压电晶体上的凝固,伴随晶体表面质量、粘弹性应力等性能的变化.由血凝各阶段的压电参数变化规律,和血凝过程的生化变化,并注意到压电传感最敏感部分为其电极表面,阐明了血凝三个阶段的复杂压电响应机理,提出了相应的压电传感方程,及从血凝压电特征曲线上提取血液流变学信息的方法.并初步应用于临床测试.
Blood coagulation on the piezoelectric crystal, with the crystal surface quality, viscoelastic stress and other properties change. Based on the changes of the piezoelectric parameters and the biochemical changes of the coagulation process in each stage of hemagglutination, the most sensitive part of the piezoelectric sensing is considered as the electrode surface, and the complicated piezoelectric response mechanism of the three stages of hemagglutination is clarified. The corresponding piezoelectric sensing equation and the method of extracting the hemorheological information from the characteristic curves of the hemagglutination and piezoelectricity. And initially applied to clinical testing.
