摘要
利用液体阻尼效应压电石英晶体传感器原理,开发了一种用于血浆粘度测量的生物传感器。阐述了该传感器的检测原理,同时介绍了探头和振荡电路的设计方法。实验表明,传感器的最大频移值与血浆粘度和密度的乘积的平方根值存在很好的线性关系。与现行的方法相比具有简单、灵敏、在线等优点。
A piezoelectric biosensors for detection of plasm viscosity is developed, which is based on liquid damping effect of quartz crystal resonator. The measuring principal is given. Simultaneously, the detector of sensor and oscillator circuit is developed. The test results show that the maximal frequency shift of sensor are linearly dependent on square root of viscosity. The proposed sensor is much more simpler, more sensitive than the traditional methods. Furthermore, The sensor can be used to on-line detection.
