糖尿病患者使用血糖监测试纸监测血糖;这些试纸受化学干扰以及环境条件的影响非常大。其制造过程和电极配置也会影响测试结果的准确性。罗氏诊断产品(美国)有限公司的研究员们使用多物理场仿真来分析血糖仪中的化学反应和电压响应。

罗氏的首席科学家 Harvey Buck 使用 COMSOL Multiphysics 研究试纸中用到的不同配置和材料。他在样本催化的化学反应过程中,分析了施压后的电响应。通过数值仿真,他预测出了电阻抗测量值对传感器机械性能的影响。他还优化了电极配置,使仿真结果受样本中细胞比率的影响最大,而受制造公差的影响最小。这些仿真结果有助于罗氏的研究团队更好地理解他们在血糖监测上所做的集成传感器设计。
