【摘要】：介绍了基于电感原理的微流体油液检测芯片,研究了油液中铁颗粒通过微流体油液检测芯片检测区的速率对颗粒计数灵敏度的影响。制作了微流体油液检测芯片,搭建了检测系统。实验研究了不同驱动速率与颗粒产生的电感脉冲信号幅值之间的关系。研究结果表明:对于同一铁颗粒,其通过检测芯片时的电感脉冲信号幅值随着速率的增加而线性减小。该研究结果为提高微流体油液检测芯片的检测精度及灵敏度提供了参考。
[Abstract]:A microfluid oil detection chip based on inductance principle is introduced. The effect of the rate of iron particles passing through the detection area of microfluid oil detection chip on the particle counting sensitivity is studied. The microfluidic oil detection chip was made and the detection system was built. The relationship between the different driving rates and the amplitude of the inductance pulse signal produced by the particle is studied experimentally. The results show that the amplitude of the inductance pulse signal decreases linearly with the increase of the rate for the same iron particle. The results provide a reference for improving the detection accuracy and sensitivity of microfluid oil detection chip.
