Calibration Free Coulometric Sensors Based on Polymeric Thin Layer Films

世界面临着巨大的环境和临床挑战，需要来自远程部署和一次性传感器的准确数据。许多重要的全球变暖（二氧化碳循环）和临床诊断（血液电解质）的关键参数可以评估与聚合物膜传感技术，但测量原理是不够强大的遥感应用。这项研究将通过将免校准测量原理（库仑法或电荷计数法）应用于此类传感器来实现这一目标，其中仪器控制将耗尽一薄层样品溶液。这构成了成功应对未来测量挑战的科学基础。

The world faces enormous environmental and clinical challenges that require accurate data from remote deployable and disposable sensors. Many key parameters important to global warming (carbon dioxide cycle) and clinical diagnostics (blood electrolytes) may be assessed with a polymeric membrane sensing technology, but the measurement principle is not sufficiently robust for remote sensing applications. This research will make this possible by adapting calibration free measurement principles (coulometry, or charge counting) to this class of sensors, where a thin layer of sample solution will be depleted by instrumental control. This forms the scientific basis for successfully tackling the measurement challenges of the future.
