摘要

我们使用平面霍尔效应传感器对磁性微珠的检测进行了微磁模拟。为了模拟这些系统的行为，考虑了磁粒子和传感器之间的相互作用。我们的结果表明，传感器的响应高度依赖于磁珠的位置。为了使传感器具有线性响应，提出了一种磁偏置装置。

Using a planar hall effect sensor for single bead detection

We performed micromagnetic simulations regarding the detection of magnetic microbeads using a planar Hall effect sensor. The interactions between the magnetic particles and the sensor have been considered in order to simulate the behaviour of these systems. Our results show a high dependence of the sensor response on magnetic beads position. In order to have a linear response, a setup for magnetic biasing the sensor is proposed.
